C.S.O.

 “So that's it, Ruko.
I won't be coming home and won't be able to go online today.
Please tell Flamia and Chiaki that I apologize for not being able to be with them.”

“(Well, alright then.
What can we do? But if Onii-chan gets caught seducing another girl again, I, no, we won't forgive you.
Aren't three beautiful girls enough to satisfy your desires?)”

Kuro immediately gave a bitter smile.

How lewd do they think he is? Kuro was very curious because, upon reflection, he rarely initiates such requests.

“I won't do that.
Just trust me for once.”

“(But I can't do it.)”

“Guhh!!!”

The answer was an unequivocal blow.

“(Onii-chan forgot that he already has a fiancée as beautiful as me, but he still seduces Chiaki.
Well, I still find it understandable since you're childhood friends, but Onii-chan hasn't forgotten his-)”

“I understand.
I understand,” Kuro interrupted.
“I can't be trusted, but can you stop bringing up all of that? Honestly, I can't take it anymore.”

Kuro screamed in his heart.
He desperately wanted to know what they thought of him.
Besides being untrustworthy and lewd, what else was he in their eyes?

“(He he he…
but we understand Onii-chan's situation, so don't worry.)”

Kuro smiled faintly.
He felt a little relieved.

“Yes, I know that, and I'm happy to be with all of you.”

“(…by the way, is there something going on between the two of you?)”

“You mean Chiaki?”

“(Yes.
Lately, she's been looking down and gloomy.
Does Onii-chan know the reason?”

Kuro didn't answer immediately.

Since that day, Kuro's and Chiaki's relationship had become somewhat strained, but it didn't mean they had broken up.
In fact, they were still intimate and made love as usual, but a cold atmosphere lingered every time they did so.

She was still angry.
That's what Kuro knew.

“…..I don't really know.
…but don't worry.
She's always like that when she's sulking.
Remember the incidents from before, right?”

“(Hmm…
that's true, but I'm still worried.)”

“I'm worried too, but trust me.
She'll be cheerful again soon, just like before.
We know what she's like, right?”

“(Hmm…
alright then.
I leave this matter to Onii-chan.
Well then, good night.)”

“Good night, ……..Hime.”

After that, the connection was cut off.

Kuro sighed softly and looked at the cityscape from Mea's house balcony.
The bustling and dazzling cityscape, yet the atmosphere felt so lonely.

He felt a little guilty, but there was nothing he could do.
No, it was more accurate to say he didn't know what he should do yet.

He glanced at the sky.
The sky was covered in clouds and the dim moonlight seemed to reflect his current feelings.

(……Hm? Why did I call Ruko “Hime”?)

He sighed once again.
He didn't know what was going through his mind right now.

Complicated and so uncomfortable.
That's what he felt.

[…that's just how I love you, Kuro-chan..]

He remembered what Chiaki had said.
The words were simple, but they were piercing and carried a deep meaning.

“If I hadn't been born into that family…?”

His unique family, different from a normal family, was what trapped him in this situation, but he couldn't blame them.
They were only doing what they had to do and what they believed was right, even if it meant sacrificing their entire lineage for it.

They were cruel for bestowing that curse upon him, but it was also thanks to that curse that he could live.
He didn't know whether to be grateful or angry at them.

Kuro sensed someone's presence approaching.

“Mea-senpai, what's up?”

Mea approached and stood next to Kuro, gazing at the city.
She was wearing pajamas, and her hair was no longer tied up.
With her long hair, she looked even more beautiful than usual.

Her thin pajamas revealed the contours of her body, enticing and alluring.
Compared to Flamia, Mea's body had a similar curvature, except Mea was taller.

“I just wanted to let you know that your bed is ready.
I'm sorry that you have to stay here.
Although I don't have a boyfriend and don't know what it feels like to have a lover, sleeping in a house filled with only women must be tough on you, Kanata-san.”

Kuro chuckled softly.

“Aren't I lucky to be able to sleep in the same room as the beautiful Mea-senpai?”

“Eh…”

Mea's face turned bright red.

Kuro not only stayed at Mea's house but also shared a room.
It was a decision made after a slightly time-consuming debate, but it was still uncomfortable.

A crease appeared on Mea's forehead, accompanied by her blushing cheeks.

“Don't say something that could be misunderstood!”

Mea clenched her fist in front of Kuro's head, giving him a sharp and intimidating look.

“I just don't want you to do anything bad to Chiyo.
I'm grateful that you saved me, but this and that are different matters.”

“…”

“Do you think I don't know that you're a playboy who flirts with girls wherever you go? I'm sorry, but I won't let you take advantage of my only little sister.”

“I didn't know you had such thoughts about me, Mea-senpai.”

“Of course.
You're known as a quiet person at school, but you're also known as a playboy, so it's only natural that I should be cautious of you.
Furthermore, don't let anyone know that you're staying at my house.
If you do, you'll soon see bloodshed.”

Terrifying.
That's how Mea was now.
She was indeed different from her usual self.
But it was this side of her that made her intriguing.

“I understand.
That's why I'll leave early in the morning to avoid being discovered.
Isn't that our agreement?”

“Good.
One more thing, if you try to take advantage of me while I'm sleeping, you'll also face divine punishment.
So don't even think about it!!”

Kuro stepped inside, seemingly ignoring Mea.

“Alright.
I won't do it either,” Kuro replied in a flat tone.

“Eh?”

Mea was surprised and followed Kuro inside.

“Hey, did you just say I'm not attractive at all, so you have no intention of taking advantage?!”

Kuro simply lay down on the bed under Mea's with a casual demeanor, as if he were sleeping in his own room.

Before closing his eyes, Kuro let out a small sigh.

“What does Mea-senpai really want? …but if you want me to take advantage, maybe I will.”

“Gii!!”

Mea froze on the spot and fell silent.

“And Mea-senpai, I don't think you'll be able to escape when I do it,” Kuro said with a faint smile.

“…………”

After saying that, Kuro closed his eyes and fell asleep like a baby.

Meanwhile, Mea couldn't say a word, and her face turned bright red.
Very red.
The smoke even seemed to be coming out of her head.

Mea gritted her teeth and clenched her fists.
A look of annoyance appeared on her face.
She didn't know if she was angry or embarrassed.

“How dare you tease me, youuuuuu!!!!!!”

Mea approached and immediately intended to hit Kuro, but she stopped when she saw Kuro sleeping soundly.
Quick.
That's what Mea thought when she saw that scene.
Even though it was late at night, being able to sleep so peacefully in a girl's room was extraordinary.
…in another sense.

Mea sighed and smiled softly.

(So you can make that kind of expression…)

Mea still couldn't believe the expression she saw on Kuro's face when he defeated the thug.
It was as if Kuro had turned into a bloodthirsty monster.
Not only that, but Kuro seemed to enjoy it.

“Yaaawwwn…”

Mea yawned widely, a sign that she was getting sleepy.

(I guess I should go to sleep too…)

Mea walked past Kuro's side towards her bed.
She lay down and covered herself with a warm blanket.

Slowly, she closed her eyes.

“Good night, Kanata-kun.”

Although she knew it was pointless to say it since Kuro was already asleep, she still did it out of habit.

“Good night, Mea-senpai.”

“……..huh?”

Mea opened her eyes and looked at Kuro, who was still deeply asleep.

“………”

Was it just her imagination? That question briefly crossed her mind, but there was a sense of doubt considering Kuro was sound asleep and even snoring a bit.

But there was another question that arose in Mea's mind.

(He's not pretending to sleep and taking advantage of me while I'm off guard, right?)

Mea's face flushed again as she remembered and imagined what would happen if Kuro actually did it.
Deep down, Mea knew that if Kuro did it, she wouldn't be able to do much about it.
She vividly remembered the hidden power within Kuro's small body.

(I hope I didn't make the wrong decision by letting him sleep in my room.)

Why didn't she ask him to sleep on the sofa or in the living room? Mea was puzzled by her own actions.

(But if I let that happen, it's as if I'm allowing him to pursue Chiyo.
Besides, I didn't expect the two of them to become close so quickly.)

Many thoughts continued to haunt Mea.
Every time she tried to close her eyes, fear and anxiety always overwhelmed her.

Should she attack or not? That's what made Mea anxious.

Seconds turned into minutes.
Time had passed by for 2 hours since Kuro closed his eyes.
It was now past 1 am, but Mea still couldn't fall asleep.

(I can't sleep…)

Her eyes felt heavy, but there was something that kept her awake.

She once again glared at Kuro with an unhappy expression.

“Now I can't sleep…
so how are you going to take responsibility?”

Although she felt a bit foolish talking to a sleeping person, it was better than talking to thin air.

“I'll keep Mea-senpai company and chat while sleeping, how about that?”

“Huh?”

She didn't expect Kuro to respond, but she still kept her eyes closed as if she were asleep.

Initially, it startled Mea, but when she realized what was happening, Mea immediately looked annoyed.

“Hoho ho…
I didn't expect you to dare to play with me repeatedly, Kanata-kun.
Do you really want a sacred punishment from me?”

Crack…
crack.
The sound of Mea's impatient hand cracking could be heard.

“Don't get angry yet, Mea-senpai.
I didn't mean to play with you, but right now I'm actually still half asleep, no, I think it's more accurate to say half awake.”

“Fine, that's a good reason, but it won't save you from your punishment.”

“Are you sure? It's midnight now, I don't think we want to disturb the neighbors and Chiyo with loud noises.
Besides, we don't want her to think something is happening between the two of us.”

“…………”

Mea fell silent and realized that what Kuro said had some truth to it.

She sighed and tried to suppress her anger which was nearing its peak.

“As I mentioned before, I'm currently half asleep.
More precisely, my body is resting, but my mind isn't.
And as you can see, I can only move my lips, but the rest of my body cannot.”

“…hmmmm, I still don't believe you.
If you wake up, just say so.
I'm not too angry anymore.”

Troublesome man, that's what's on Mea's mind right now.

“Unfortunately, I'm not joking.
This is one of the techniques specialized for resting anywhere and anytime without lowering my vigilance.”

“…..heee…
I don't know about such a technique, but I heard about it somewhere.
But I forgot where.”

The technique Kuro is currently using is one of the Kamikiri-ryuu [Sleeping Dragon].
It's just a simple technique to allow the body to rest in any situation.

“Whether you believe it or not, it's up to you, Senpai, but now I will keep you company and chat until you can sleep.
Is that enough?”

“…..hmmm..”

Mea looks hesitant.

She wants to sleep soon since she'll be busy as the student council president, but she can't close her eyes even for a moment, so she doesn't have many options in this situation.

“But I don't have many topics to talk about, so I'll just play the role of a listener.
Consider me as your confidante, Senpai.”

“…”

(That's how it is.
He must be considering my position as the student council president with many issues.
That's good.)

After that, Mea starts talking to herself as if in a long monologue.
Most of the topics discussed are issues that occur in school.

Although Kuro is just playing the role of a listener, he responds well.
He even gives some satisfying advice to Mea.

Time passes quickly.
It's already past 3 in the morning.
Mea yawns several times, a sign that she's getting sleepier, but she still finds it difficult to close her eyes.
At the same time, the conversation topics begin to diminish, and eventually, there's nothing left to talk about because it's been one-sided.
It's a bit frustrating.

“Well, let's talk about you now.
It wouldn't be fair if I'm the only one who keeps talking.”

“Unfortunately, I don't have anything that needs to be discussed.
Senpai should just go to sleep!”

“Tch!!”

Mea gets annoyed and throws her pillow right at Kuro's face, covering him with it.

..and because he can't breathe, Kuro finally opens his eyes and pushes the pillow away from his face.
A bored expression is the first thing he shows.

“……I indeed don't have many topics to discuss, Mea-senpai.”

Kuro glances at Mea, who still looks annoyed, and lies down while using both hands to support her chin.
Mea's gaze is somewhat intimidating.
It briefly reminds him of Chiaki.

“Here's the deal, Mea-senpai, feel free to ask me anything.
As long as I don't mind answering, I'll answer any question.”

“Hmmm…”

Mea considers Kuro's suggestion.

“Alright.
It's better than doing nothing.”

Kuro smiles softly and tosses the pillow back to Mea.

“Kanata-kun, first, what's your opinion about CSO? You play that game, right? I still don't understand why so many people like it.”

Kuro understood what Mea meant and felt.

“…to be honest, I also don't know why people like it.”

“Eh? But didn't you join the club because you always play CSO after school?”

“I don't know where Mea-senpai heard that from, but that's not the reason I didn't join the club.
I told you before, I'm a busy person, but that doesn't mean I only spend my time playing CSO.
Do I look like a game maniac to you?”

“…hmm, you don't seem particularly interested in CSO, but there must be another reason why you play it.
Could it be because of a girl named Flamia?”

“That's just one of the reasons why I play.
She is my wife, and only in CSO can we spend time together and meet more freely.”

Mea's face turned red.
She understood what Kuro meant.

CSO was the place where they could be affectionate and express their love freely.
Although it wasn't the real world, the game world that was almost like the real world allowed them to love each other like a couple.

Mea had heard about this before.
A game that closely resembled the real world was used by couples to meet even when they were far apart or when they were abroad.
Furthermore, the game was also used for family gatherings and the like.

Mea glanced at the ring on Kuro's ring finger.
She had asked and heard that the ring couldn't be taken off, so Kuro always wore it at school.
It wasn't that the school prohibited wearing accessories, but a ring on the ring finger was a sign that someone was committed.

“…I'm sorry, because of me, you couldn't meet her today.”

“Ahaha, don't worry, Mea-senpai.
She's not the kind of person who will-“

“? Kanata-kun?”

Kuro suddenly stopped himself as he realized Flamia was not that kind of person.
Flamia was not someone he could negotiate with when it came to matters of affection.

Suddenly, Kuro's face turned pale.

“It's nothing, Mea-senpai.
Let's not talk about her anymore.”

Kuro shuddered and quickly looked away as if experiencing severe trauma.

“Hm? Could she get very angry?”

Mea immediately felt guilty.
Now she understood the answer to the question that had always been on her mind.

“No, but she will definitely force me to make love for hours until she's satisfied.
I don't think that's a good thing.”

“………”

Make love? Mea was already a teenager.
Of course, she knew what Kuro meant.

“..Kanata-kun…
I didn't expect you to be so lewd.”

“Why does Mea-senpai say the same thing as the other three?”

“……”

“Just so you know, even though I make love with them every day, it doesn't mean I force them to do it.
In fact, every day, I tr…aha…”

“…….”

Kuro stopped himself as he realized that what he was saying was something he shouldn't say and should remain a secret.

Slowly, Kuro looked back at Mea, who had been silent all this time.

“Mea-senp-“

Kuro couldn't bring himself to look again as he saw Mea filled with a scary and dangerous aura.
This time, it reminded him of Ruko.

Not only was she surrounded by a dangerous aura, but Mea was also ready to throw herself with a pillow.
Although it was a pillow, from the aura of the pillow, it was not an ordinary pillow.

“Kanata-kun…
I didn't expect you to be more depraved than I thought.
Not only are you make love with your lover, but you're also not satisfied make love with your childhood friend at school.”

“…….?”

“And now I hear you mention another person.
Oh yes, I remember you're also a Siscon.
…don't tell me you're also doing it with…”

A chilling aura emanated from Mea.
The beautiful girl had transformed into a demon.

“….aha ha ha…”

Kuro couldn't deny it.
He had been found out.
Now all he could do was accept Mea's divine punishment.

“Y-you…p.pervert…
eh??!!!!”

Mea finally threw the pillow with all her might, but she slipped on her blanket and ended up falling right onto Kuro.

Baamm!!! The sound of the object falling resonated loudly.

After a few seconds, they both regained their senses, and it was at that moment that they realized something more serious had happened.

“……….”

“……….”

Their lips were pressed against each other, experiencing the softness of each other's lips.
Yes, they were kissing.

Silence fell between them, without either of them attempting to break it.
Time seemed to stand still, and they couldn't comprehend what had just happened.

But for Kuro, the sensation he felt didn't only come from Mea's lips, but also from the two objects that were Mea's breasts pressing against his body.
The warmth and softness of Mea's body were also vividly felt by Kuro's five senses.
And because Mea was on top, he found it difficult to move his body or even struggle.

He felt a sense of déjà vu.
This time, he remembered the first time he kissed Flamia.

Mea truly reminded him of the three of them today.
And that made him feel guilty for allowing this to happen.

“……”

After about a minute, Mea's face suddenly turned red, and her eyes widened.
It was as if she had just realized what had just occurred.

Contrary to Kuro's expectations, Mea didn't seem panicked and slowly released her lips from Kuro's.
She also didn't appear angry; instead, she looked bewildered.

“Hmmm…”

Mea touched her lips with her finger and examined the sensation she felt.

(Oh no!!!!!)

Kuro immediately turned pale and broke into a cold sweat, realizing that he was about to receive divine punishment.
From his past experiences, he knew he was in big trouble.

Should he run away? He could do that, but it would be cowardly.
So he decided to assess the situation first and look for an opportunity to apologize, even though he believed he was not at fault in this matter.

“So, is this what they call a kiss?”

“Eh?”

Kuro couldn't react much upon hearing that from Mea's lips.

Suddenly, Mea leaned closer, pressing her body against Kuro's.
For some reason, Kuro saw a faint smile appear on Mea's lips.

“Senpai, I apologize for accidentally kissing you, and I know it's not easy to forgive, …but could you please move away from me?”

A dangerous position.
Although he often found himself in this kind of situation with his three wives, being in such a position with a girl he had no relationship with was a temptation in itself.

“….fufu…
Kanata-kun, …do you know that was my first kiss?”

“Eh?”

Kuro wanted to shout if Mea was imitating Flamia? But he stopped himself.
At the same time, it meant that Kuro had taken Mea's precious first kiss.
Another question arose in his mind, was this perhaps his luck?

“Don't worry, I'm not angry.”

“?!”

Kuro was surprised when Mea suddenly kissed him.
He couldn't dodge it because they were already in such close proximity.

Unlike the accidental kiss, Mea kissed Kuro aggressively this time.
She even boldly slipped her tongue into Kuro's mouth.
Mea kissed Kuro with a French kiss.

After about 5 minutes, Mea finally released Kuro's lips.
Her tongue extended, licking the drooling saliva.
This was a side of Mea that Kuro had just discovered.
And he never expected Mea to be so bold.

The question was, why?

“Senpai? What are you doing?”

“As you can see, I'm undressing you.
It would be troublesome during our lovemaking.
Don't get me wrong, it's my first time too.
Hm? I didn't expect you to be so excited already.”

“Lovemaking?”

Kuro stood up and forcefully pushed Mea's body back.
Now Kuro was on top and gripping both of Mea's hands.
It seemed like Kuro intended to attack Mea for a moment.

“Mea-senpai, please stop! I know I made a mistake by kissing you, and I understand the value of a first kiss, so I beg you, Senpai, you don't have to do this!”

Mea didn't respond immediately and instead, let out a small sigh.

“Haa..
shouldn't you be happy?”

“Not in a situation like this.”

“You're a strange man.
Usually, men would readily indulge their desires after someone has gone this far.
If you're not interested, you must have a strong reason to still be able to restrain yourself.”

“…….”

Mea smiled faintly.

“Your eyes say it all, Kan- Kuro-kun.
You're not someone who easily falls in love over a trivial reason, am I right?

“Hmmm…”

Kuro glanced away and loosened his grip.
But what Kuro did was a mistake.

Seizing the opportunity, Mea once again pulled Kuro towards her and pinned him down.
Not only that, she immediately kissed Kuro without hesitation.

“…..”

Kuro was now completely confused about what was happening to Mea.
Suddenly, her behavior had changed one hundred and eighty degrees and she became more like a cheap woman.

What surprised him, even more, was that he felt the urge to attack Mea.
The power capable of easily breaking human bones seemed to disappear.

And amidst all of that, for some reason, he sensed an aura and a sweet fragrance from Mea.

“..ahhnnn..
fu fu….”

Mea released the kiss.
She flashed a mischievous smile while wiping the saliva dripping from her lips.

Erotic.
That's what Kuro thought.
It was the first time he had seen a girl behave like that.

With a small and adorable smile, Mea unbuttoned her pajamas without hesitation and tossed them to the floor.
This time, she was only wearing her underwear.

Her beautiful curves and smooth skin were now incredibly tempting and right in front of Kuro.

Mea's face turned red, but there was no sign of her being embarrassed or hesitant about doing all of this on top of Kuro's body.
She then intended to remove her underwear and at that moment…

“Senpai, why are you suddenly doing this?”

“Isn't making love something that should be done on the first night between husband and wife?”

“Yes, that's true, but what's the connect- hey, don't take it off so casually.”

But Mea ignored Kuro's words and removed her underwear, tossing it somewhere in the room.
Now, two soft objects were right in front of Kuro, not to mention the alluring red fruit as their centerpiece.
He also felt Mea's body suddenly become very hot.

If he hadn't been inexperienced in seeing a girl's breasts, he might have lost his mind and attacked Mea right away.
But before that, there was something he wanted to know.

“Fu fu..
do you like it? Don't get me wrong, I'm also embarrassed to do this, but what can we do? We're going to make love.
If I'm embarrassed, we'll never get started.”

“Can you explain what's happening, Mea-senpai? Honestly, I still don't understand what you mean.
And just so you know, I could leave if I wanted to, but that would only be running away, so…”

Mea smiled faintly.

“I understand.
I will explain why I suddenly did all of this, but I will still make love to you no matter what happens.”

“……”

Kuro turned pale.

“Do you know why I've never had a boyfriend? Every month, there would be one or more guys confessing their feelings to me, and you know what? I've never had a reason to reject any of them.”

“Eh? …then why?”

“I gave them a condition.
And the condition was that even though we're dating, we wouldn't kiss or show affection like a normal couple.
You would definitely reject that condition outright because being intimate with your lover is something you do with your lover, …but that's not the point.
Kuro-kun, you surely understand what I mean.”

“Why did you impose that condition, is it true?” Mea nodded slowly while giving a small smile.
“…The biggest reason is that it's a tradition, but traditions arise for a reason.
And this particular tradition is so binding that someone like me, the firstborn in the family, cannot refuse it.
No, I believe I would be in deep trouble if I didn't follow that tradition.” Kuro immediately understood that the tradition Mea was referring to might be related to the first kiss.
Kuro realized he was in serious trouble.

“First, let me explain how this tradition came about.
If you don't know, you'll surely be confused as to why such a tradition exists.”

“……”

“We are descendants of half-human and yokai beings.
I'm not entirely sure if we can be called yokai, but to put it simply, our ancestors were a type of succubus.
It's hard to believe and doesn't make sense, but that's the truth.”

“…”

“And you must have an idea of what a succubus is like.
And that's what's happening to me right now.
I am currently filled with passion, without any sense of shame, even though it's my first time.” One by one, the puzzle pieces started coming together, and everything became clear.
The reason why Mea never had a boyfriend despite being so popular.
The reason why she imposed an impossible condition on the men who confessed their love to her.
The reason why she changed after kissing.
And after realizing all of that, one thing became clear to Kuro: he could never stop hurting others.

“That's why the first kiss is also a symbol of marriage for me.
There are severe consequences for me if I can't control this desire.
Honestly, I don't want to kill anyone.”

“…” “Do you understand? I'm glad that you were the one who took my first kiss.
I can see that you're not the type to play with people's feelings and hurt them.”

“…you're wrong, Senpai.” “?!!”

Once again, Kuro immediately grabbed Mea's shoulders and pulled her back to their previous position.
Kuro was now on top of Mea, who was completely naked, and he tightly held both of her hands.
Kuro could have done anything to Mea at that moment, but nothing happened, and instead, Kuro slumped down weakly.

“Kuro-kun?”

“I'm not as good as you think.
I have unknowingly hurt the woman I love and care about.”

“…”

“Senpai, you know, I also come from an abnormal family.
Now Senpai knows why I have strange powers that would get me into trouble if I use them carelessly.
But just like you…
there's a tradition I have to follow as the eldest child, and I have fulfilled that tradition.
I…
I married my younger sister and at the same time, my cousin.”

“?!”

“…and I suppose Senpai can guess what my daily life is like.”

At that moment, Kuro looked at Mea with a sorrowful gaze, but at the same time, his eyes turned red.
Kuro revealed his true self.
“You said I'm not the type to play with a woman's heart, but can you still say that after knowing that I'm currently in a romantic relationship with three people at once? Not only that, I've made them accept each other and willingly share me with other girls.
I am the lowest of human beings…”

“………”

Mea could only remain silent.
Mea could feel Kuro loosening his grip, but Mea didn't do much and remained silent in place.

The man above her was someone she had just met a few days ago because he received punishment.
Initially, I thought Kuro was a strange and mysterious man.

When she was with him, she realized that the students at school didn't want to talk to him and instead ignored him, no, if she said they ignored him, then that wouldn't be accurate.
Kuro seemed to erase his presence to the point where no one noticed him.

In my heart, Mea asked, why does he act like that?

Mea knew the answer, and the answer was too simple.
Kuro simply didn't want to form relationships with others.

Mea was certain that if Kuro were a little more open, he would become one of the most popular guys at school.
She knew that because she could sense that aura from Kuro.

But when Mea heard and learned that Kuro simply didn't want to draw attention because he had managed to get a beautiful woman as his girlfriend, She immediately rejected that thought.
From the beginning, Kuro didn't want to involve himself with others.

“….and I think Mea-senpai has already seen the real me.
…unlike Senpai, who has succubus blood within you, I have always been the devil itself.
Now, can Mea-senpai give up on me-“

“No, I won't.”

Mea immediately hugged Kuro's neck and didn't let him go.

“Why, Senpai? Even though we're doing this, I can't give you love and will only hurt you, but at the same time, I don't want to hurt the other three.
…Senpai, why don't you understand?”

“You're wrong, Kuro-kun.
In fact, after hearing everything from you, I am even more interested in you.
I didn't make a wrong choice by choosing this.
And one more thing, don't say that you can only hurt the people you love.
If you do that, it means you doubt their love and truly hurt them.
That's when you truly become the lowest of human beings.”

“!?”

“You think you hurt them because you know every woman wants to make their lover exclusively theirs and monopolize their lover completely…I don't deny that and can't imagine what they feel when the person they love brings another girl and tells them they're in a relationship.”

“…….”

What Mea said hit the mark.
He hadn't cared much about what the three of them felt all this time.
Now he understood why he couldn't be trusted.

That was the truth.
And he made that mistake again now.

“But have you ever thought about why they are willing to accept and share with another woman?”

“……eh?”

“All three of them love you, and they know that someone else has the same feelings.
That's why they also know the feeling of being unable to be with the person they love, which is you.
And do you understand my point? The three of them don't distrust you; on the contrary, it's because they trust you that they are willing to share.
They know you can love all three of them at the same time, just as you would love one person.
Kuro-kun, you should be proud because they can trust you.
Stop blaming yourself or thinking that you have hurt them.”

Kuro fell silent.
In his mind, he contemplated all of Mea's words and compared them with the reality and problems he was facing now.

And after a few moments of silence, Kuro smiled faintly with tears streaming down his face.

“Thank you, Mea-senpai.
Now I know what I have to do.”

(Chiaki, I'm sorry.
I will soon make amends for my mistakes and apologize for not realizing what you wanted.)

Kuro is no longer hesitant and has found a way to bring Chiaki back to her normal self.

“You no longer seem hesitant.
I'm glad,” Mea said.

“Yes, thanks to you, Mea-senpai,” Kuro replied.

“Now, can we continue? Don't you know that I can't hold myself back any longer?” Mea asked.

“………eh? Sen…pai?” Kuro questioned.

“Don't worry, I think adding one or two more people won't be a problem, right?” Mea suggested.

“………………………………………………………..I knew I would regret this,” Kuro sighed.

Mea smiled softly upon hearing Kuro's response.
She then pulled Kuro's head and gave him an affectionate kiss.
Kuro reciprocated Mea's feelings without resistance, following the flow of their emotions.
And deep inside, he screamed,

(I think I need to reconsider this…)

…at the same time, this was how Mea ensured she could fall asleep peacefully with a happy smile.

“Onee-chan…
Onee-chan…
wake up, how long are you going to keep sleeping? Have you forgotten who you are?”

After knocking on the door loudly and shouting, Chiyo finally entered when she didn't receive any response from her sister.
Usually, Mea wakes up earlier than her, but it seems Mea had a specific reason for oversleeping.
Chiyo could guess what caused it, which was Kuro sleeping in the same room.
Every girl would feel nervous, so she found it somewhat understandable.

“………..”

Upon entering, Chiyo found neatly folded bed sheets and couldn't find Kuro anywhere.
Kuro had promised to leave early in the morning, so Chiyo knew that Kuro had already left without them knowing.

Chiyo smiled softly.

“Too bad, I prepared breakfast for him.”

Chiyo walked towards Mea, who was still sound asleep.
Her eyes showed signs of sleeplessness. 

Chiyo gently shook Mea's shoulder to wake her up, and that's when she felt her hand directly touching Mea's skin.

“………….”

An unpleasant feeling immediately overwhelmed Chiyo.
She wanted to dismiss that thought from her mind…
but…

She quickly pulled the blanket off Mea and looked at her sister.

“….haaa..
thank goodness…
I was overthinking it.”

She found Mea still wearing her pajamas.
The reason she touched Mea's skin directly was that a few buttons of Mea's shirt had come undone, loosening her clothes on the shoulder area.
She was so defenseless, but Chiyo knew Kuro wasn't that kind of person.

Chiyo shook Mea's body vigorously, and after a few tries, Mea finally opened her eyes.

“Onee-chan, if you don't wake up, you'll be late!”

After seeing her sister slowly wake up and sit on the bed, Chiyo left with a happy smile.

“…………….hnnn..”

As her consciousness returned, the first thing she remembered was the events of the last night, but at the same time, she wondered if what she did with Kuro was just a dream.

She was still wearing her pajamas, so it was highly likely that last night was just a dream caused by lack of sleep.

“Ahh..
uh-oh, it's already this late..”

Mea scratched her slightly messy hair.
She was slightly surprised to realize she had only a little time before being late for school.

Finally, after gathering her remaining energy, she got up and headed to the bathroom.

“Why am I so tired?”

She often stayed up late and slept in, but this was the first time she felt so exhausted.

“!”

When she opened the bathroom door, she finally noticed something that had been making her uncomfortable since earlier.
Without a word, she carefully felt her buttocks and waist.
And finally, she realized what was uncomfortable and what she wasn't wearing.

“Ah…
where are my underwear?”

“Well…
I guess it's not a big deal.”

With a smile, Mea entered the bathroom.
She was happy.
Happy because what she did was not a dream.

While Chiyo could only wonder in her heart, why does Mea sing in the shower? No, from the beginning, taking a shower in the morning was something unusual for Mea.

But she knew that something good must have happened.
Chiyo felt happy knowing that.

Chiyo looked at her phone and gazed at the wallpaper, which was a photo of Akame.

Suddenly, she smiled with joy.

“Akame-kun, no, Kuro-san…
I can't believe you're so close…”

On the crowded train, Chiaki stood with a blank expression.
She was on her way to school as usual, but unlike before, this time she was alone.
Although being alone was actually her usual routine before she married Kuro in CSO, it was not a big deal for her.
But when she remembered that Kuro couldn't accompany her because he stayed over at his friend's house, Chiaki immediately felt that something unusual had happened.
…Or Kuro did something that involved another girl.
It was their long-standing relationship since childhood that made her think that way, but what made her think that was that she knew a fact that no one could deny.

Kuro didn't have many friends.

That fact sounded a bit cruel and evoked sympathy, but there was nothing she could do about it.
Having relationships with others would only bring more problems.
It didn't mean that Kuro didn't want to get involved in problems, but from the beginning, he wasn't allowed to do so.
If this was related to Kuro's tradition or family, it couldn't be said as a definite “yes” or “no”.
Complicated and becoming even more complicated.
Chiaki was still fortunate because she only knew a little about Kuro's family.

Youkai, monsters, gods, goddesses, and all mystical creatures from legends were real.
Those were just a few truths she learned after getting to know Kuro.
And she had seen the evidence with her own eyes.
The CSO they now knew as a game was also one of those proofs.

“…………”

Not long after, she arrived at her destination station.
She got off the train and found Fumiko waiting for her.
They had planned to go to school together.

It wasn't the first time they did it; in fact, they almost went together every day now.

“Good morning, Chiaki-chan.”

“Good morning.
Are you not with that idiot again?”

Fumiko simply nodded.

Just like herself, who always went with Kuro, Fumiko always went with Yuya, but for the past few days, they hadn't gone together.

“Well, that's how it is.
Lately, he's been late quite often, to be honest, I'm a little worried.”

While chatting, they walked together towards the school, which wasn't too far from the station.

“You don't need to worry.
A foolish person like him doesn't need to be worried about it.
I'm sure he's doing something stupid again.”

“…I hope so too.”

“…………..”

Silence fell for a few moments.
Both of them realized they were discussing an unpleasant topic.

“Oh, by the way, has your class done Chapter 5 of math?”

“Not yet, but I'm sure Kuro-chan's class has.
If you ask him, I'm sure he will…”

Chiaki suddenly stopped.
She didn't want to discuss anything related to Kuro, but somehow she couldn't let go of it.
Was this what they called a bond?

“I understand.
I will ask him.
Honestly, I'm not very good at math.”

“Why not ask that idiot? Although he rarely uses his brain, he's quite smart in math.
Plus, you're in the same class, right?”

“…about that, for some reason, he has seemed exhausted these past few days.
He always goes straight home after class.
It's not like him, so I thought he must be busy.
I didn't want to bother him.”

“I see…”

Fumiko chuckled bitterly.

“Oh, by the way, where is Kuro-san?”

“I don't know, maybe he's dead or busy fooling around with some girl.
I don't care about him.”

“Ah ha ha…
fooling around with a girl, that's too much…
even though you two are…”

Chiaki stopped and stared directly at Fumiko from a very close distance.

“YOU…
KNOW NOTHING about him.”

After saying that, Chiaki continued walking.
Fumiko, who was still slightly surprised, could only sigh inwardly.

Not long after, they arrived at school.
They entered together with dozens of other students.

They separated in the hallway since they were in different classes.
And there, Chiaki saw Kuro walking towards her, holding a small book in his left hand.

“…”

Chiaki immediately gave him an unhappy look.
But she tried to stay strong and kept walking past Kuro, who showed no interest in her gaze.

They passed each other.
No one greeted or acknowledged each other.
Cold.
That was the atmosphere around them.

But-

“?!”

Chiaki suddenly stopped.
Her eyes widened and she immediately turned to look at Kuro.

She distinctly remembered the smile when they passed each other.
Not only that, but she also remembered the aura emanating from Kuro.

Both belonged to Kuro, but at the same time, they didn't.

(No way…)

There was only one person Chiaki knew who had that kind of aura and smile.
And that person was…

“Shiro?”

Kuro just smiled and continued walking, ignoring Chiaki's surprised gaze.
She had suspected this.

Why did Shiro appear? That was the thought that crossed Chiaki's mind when she saw Kuro meeting with the student council president in the school hallway.

And what was even more surprising, there was an aura coming from both of them.
An aura that she was very familiar with and knew.

“…Kuro…chan…”

What's happening? What's happening? Why is it like this?

Chiaki didn't know the answer.
But she knew one thing.

“Welcome back…
Kuro-chan.”

 

Note :

=> As someone with succubus blood, Mea has an erotic body.
Just like in myths, her blood gives her a strong charm and charisma.

=> The first kiss triggers the succubus blood within Mea's body to awaken.
If left unchecked, she would become a creature that continuously absorbs energy and becomes a full-fledged succubus.
To deal with this issue, Mea must continuously absorb energy from the same source as the person she first kissed.

=> This is the beginning of the encounter between the succubus and the demon.
