C.S.O.

 A few days have passed since Kuro's battle with the Demon God.
The fight is still a hot topic in the online world, gaming communities, real life, and even national news.
The recording of the battle has already been viewed 10 million times on Niconico Douga within just a few days.

 

It was the most intense battle, one that can be said to be beyond human capability or even game level.
Yggdrasil Group, the game developer behind CSO, has not provided much explanation about what happened, especially regarding the sudden appearance of the formidable enemy, the Demon God.

 

In the end, the battle concluded with an explanation about how strong their enemies were and how strong they would become if they kept playing.
No one knows the truth about the battle, but for Kuro, who knows the true power of their enemy, it's bad news.

 

Two weeks later, Kuro became a famous and feared Liberator.
This time, not because of marrying Flamia, but because of the power he displayed.

 

As a result, even in the real world, no one didn't know about him.
He became a topic of discussion at school, and a fan club was created for him.

 

But perhaps the biggest change still happened to Kuro.
His eyes now have a red color with two fused boxes, resembling chains.
It doesn't mean that Shiro took over, but now they have become one and cannot be separated like before.

 

Despite that, Kuro's attitude hasn't changed.
As long as he remains the same as before, Chiaki and Flamia will continue to love him.

 

Unfortunately, Ruko can't do the same.
Unlike the two of them, Ruko comes from the Kanata family.
She knows well what happened to Kuro.
Although Chiaki knows some things about her family, she's still an outsider with limited knowledge about them.

 

The Demon God may be a big problem, but for Ruko, the real issue is what has happened to Kuro now.

 

During the lunch break, Ruko is alone on the rooftop.
She has always been alone, without friends to share her thoughts with.

 

From the beginning, she has been alone.
She may be perfect, but it's precisely her perfection that has made her feared and isolated.

 

She has grown accustomed to it and doesn't need pity from others.
As long as she has Kuro and Chiaki, she can overcome any problem, no matter how heavy it may be.

 

But the current problem is one she can't face alone.

 

“Um?”

 

Her phone suddenly vibrates.
She checks it and reads the incoming message.

 

She sighs and shows an unhappy expression.

 

“They're finally starting to move…
I guess this is for the best.
For our sake, I think we have to do this to you again, Onii-chan.”

 

Ruko then replies to the message with a somber look.
She's sad, but she knows this is what she has to do for the person she loves before it's too late.

 

Shortly after, Ruko receives a reply message.

 

“We will be coming home soon.
Wait for us, Ruko.
By the way, what would you like as a gift from England?”

 

Ruko smiles faintly.
Then she slowly replies to the message.

After finishing, she continues with her lunch.
But suddenly, she stops as a cold breeze starts to blow.

“We will kill the person we love for the second time.
Are you okay with all of this?”

“You already know the answer, Miki.”

Meanwhile, at school, Kuro is currently having lunch with Chiaki.
Chiaki, acting a bit spoiled, asks to be fed like a child.
Kuro doesn't refuse, but considering their situation, it's not the right time to do so.

 

“Is this what they call a real-life harem? You're really good at making people jealous, you jerk!”

 

“Hey…
Chiaki is my wife (in CSO), there's nothing wrong with us doing this.
Besides, this isn't the first time.”

 

“You mean you've done it not only with Chiaki-san but also with Flamia-sama and even with Ruko-chan? Hey…
if anyone else finds out, you could be killed, you know!”

 

“Don't say it as if they can do it easily.
If they want to kill me, go ahead, but I won't hesitate to kill them either.”

 

“Err…
for some reason, you're a bit more cruel than usual.
Do you know that?”

 

“….”

 

“Or are you deliberately doing it to toy with me?”

 

“I don't know, Yuya.
But it could be both.”

 

“Damn…”

 

Yuya finally couldn't say much anymore.
He quickly finishes his lunch, seemingly avoiding the issue.

 

Meanwhile, Fumiko, who is standing and eating next to Yuya, can only smile bitterly.
She can't comment much on the affection shown between Kuro and Chiaki.

 

Although they both know that Kuro and Chiaki have a special relationship, Kuro and Ruko are more than siblings, and Kuro is Flamia's lover, they still don't understand what's really going on.

 

“Kuro-san, I apologize in advance, but I've always been curious about your four-way relationship.
Honestly, I don't understand at all.”

 

“If you think about it too much, you might go crazy.”

 

“Huh?”

 

“I'll explain it in a simple way so even an idiot can understand.”

 

“Wait, why did you call me an idiot?” Yuya protests.

 

“Simply put, the three of us are Kuro-chan's wives, but only Ruko-chan is his legitimate wife in this world.”

 

“…..”

 

“….”

 

Fumiko and Yuya are dumbfounded.

 

“Hey…
wait, what do you mean? I still don't get it.”

 

“Simply put, the three of us have done it with Kuro-chan.
Do you understand?”

 

“Huh?!”

 

Yuya's eyes widen.
He even turns pale upon understanding the meaning of Chiaki's words.
Meanwhile, for some reason, Fumiko's face turns deep red.

 

“And just so you know, our members might increase even more…
right, Kuro-chan?”

 

“Stop kidding around.
You make it sound like I'm a wild beast that will prey on any woman I meet.”

 

“…but you did it, didn't you?”

 

“I don't know, but maybe I will, hehehe…”

 

Chiaki sighs.

 

“Your nature really gets us into trouble, Kuro-chan.”

 

While chatting and half-joking, in a frightening manner, someone suddenly appears.

 

“Ah…
there you are.”

 

A girl with a ponytail approaches Kuro.
She is Mea, the head of the student council.

 

“I knew you two would be getting cozy here.
You really don't choose the right place for it.”

 

Yuya and Fumiko are shocked by Mea's familiarity.
Although they know that Mea and Kuro have a connection because they worked together, from what they can see, Kuro has already made his move on Mea.

 

“Fumiko, I

 

 think I'll run 10 kilometers.”

 

“Why suddenly?”

 

“For some reason, this sight is too painful for me.
Maybe by running, I can forget about it.”

 

“I think if you see it every day, you'll never forget.”

 

“…ughh…
don't remind me of the bitter reality!”

 

Meanwhile, Chiaki and Kuro face Mea.

 

“What do you want here? Do you know you're bothering us? Go away!”

 

“Aha ha…
I didn't mean to bother, but I will if I'm not busy with student council activities.”

 

Chiaki squints her eyes.
She senses the threat.

 

Mea turns her gaze to Kuro.

 

“So, the rumors are true.
I've seen those eyes before, but could they be real?”

 

Until now, Kuro claimed to wear contact lenses.
It was only to prevent suspicion from curious people, but that method wasn't enough to deceive someone who had seen his eyes before.

 

“Mea-senpai has seen my devilish eyes.
I guess Mea-senpai knows whether they're real or fake.”

“Kuro-chan, I think I want to hear a more detailed story from you.”

Kuro's face immediately turned pale.
He knew he was in big trouble for saying something he shouldn't have said.

“..
alright, but if possible, only you should know.
We don't want those two to find out about this.”

Chiaki sighed and refocused on Mea.

“You really are an untrustworthy husband.
But I don't think it's the right time to argue.
So what do you want to meet Kuro-chan for, Mea-chan?”

“It seems you misunderstand.
I don't just want to meet Kuro, I also want to meet you.
Basically, there's something I want to discuss with both of you.”

Mea stepped towards Fumiko and Yuya, who had finished their lunch.

“Sorry, but I want to talk to the two of them, so…”

“Yeah, yeah.
We understand.”

Yuya wore an unhappy expression.
He packed his lunchbox and pulled Fumiko's hand.

“Let's go, Miko-chan.
We don't want to get involved in World War III.”

“Huh, Yu-kun..”

Fumiko and Yuya finally left, holding hands.
After they were gone, Mea approached Kuro and Chiaki again.

“Heh..
they really are a harmonious couple, don't you agree?”

“Yes, but Yuya isn't the type of person who would attack directly.
I think it will take a long time for them to be together.”

“He's just a fool.
Anyway, let's get back to the topic.
What do you want to talk about?”

Mea placed her hand on her chin and pondered.

“Hmm…
how should I explain it? It's a bit complicated.”

“Never mind, don't beat around the bush.
That's not like you.”

“Yeah, you're right.
But I really don't know how to do it.
Oh well, why don't I just tell you what happened.”

Mea stood up as usual.
She woke up quite late because she had been working on many tasks.
It was at times like this that Chiyo would wake her up.

But when Chiyo opened her bedroom door, she couldn't find Mea anywhere.

When she opened her eyes, Mea saw a sky she had never seen before.
The sky was bright blue with many floating objects.

Mea then woke up.
She looked around and saw a dense forest.

Strange.
That's what she thought.
Could this be just a dream? Mea was curious and finally pinched her cheek to confirm whether it was a dream or not.

But she felt pain.
She still couldn't believe it and did it again and again until both of her cheeks turned red.

“This is not a dream.”

Forced to accept reality, Mea was puzzled by the next question.

“If this is the real world…
where am I now?”

The world she knew did have forested areas, but the forest she saw was not like any forest she knew.
After observing more closely, the objects she saw in the sky were floating islands.

“……”

(Don't tell me I'm trapped in a fantasy world or something.
…this is really not funny at all..)

Still unsure of what was happening, Mea finally decided to assess the surroundings.
She pushed through the forest and tried to find clues about where she was.

After a while, she finally found a clue.
It turned out she was currently in a fantasy world.

The place she was in was one of the floating islands.
She observed from the edge of the island and saw what was happening.
Flying monsters, giant trees thriving, and there were battles being fought by people dressed strangely.

“…..”

Mea then returned to the forest.
She still didn't know what was happening, but she realized that the scenery she saw was something she had seen before.

“No doubt, I finally understand what actually happened to As*na.
Hey…
this is not the time to think about that.”

1

How could she be in that place and why was she trapped in a game? That was the real problem.
She didn't know the dangers of staying there.
The most important thing was figuring out how to return to the real world.

Mea continued to explore the forest, hoping to find something that would lead her back home.
But after walking for a while, she found nothing.

Mea finally grew tired and took a rest.
She leaned against a tree.

“It's useless, I didn't find anything.
I should wait for help to come.”

Although deep down Mea knew the possibility was small, there was no harm in hoping.

“Why do I remember Kuro-kun?”

She didn't understand.
They had done it with Kuro, but after that, there was no special connection between them.

“Could this be my punishment?”

Mea lowered her head and hugged her knees tightly.
Feelings of sadness and confusion overwhelmed her, but for some reason, she didn't regret it.

“Hehe…”

Tears flowed from her eyes.

“I knew it, this is my puni- hmm? What is this?”

Mea suddenly noticed something on her finger.
It was a ring.

“It seems I've seen this ring before.
It's the same ring as Chiaki's.”

Then Mea realized another oddity.

“Wait, why am I-?!”

The ground started shaking.
Mea thought it was an earthquake, but considering she was on a floating island, an earthquake was impossible.

Mea then heard a rumbling sound from behind her.
She turned around and saw the source of the earthquake, a monster.

The monster was shaped like a giant lizard, the size of a bus.

Mea turned pale.
She sensed the danger and immediately started running with all her might.

“THIS IS UNACCEPTABLE!!!!”

Mea ran and shouted.
The most important thing was to save her life.
She ran towards the dense trees to evade the monster, but the monster easily destroyed the trees.

Mea kept running and running.
She didn't even care about her torn clothes.

After running for a while, she finally saw a light.
She saw the light in a corner.
Without hesitation, Mea ran towards the light.

She glanced back and saw the lizard monster still chasing her.

“?!”

That's when she reached the light, but unfortunately, it was a mistake.
The light came from the edge of the floating island.

Mea was shocked and didn't have time to slow down, so she fell off the edge.
Unfortunately, that wasn't the worst part.
Another monster flew towards her, preparing to devour her.

At the edge of death, for some reason, she remembered someone.

“Kuro-kun…”

Mea's ring glowed, and at the same time, her body disappeared.

When Mea opened her eyes again, she was back in her bed.
Everything she experienced felt like a horrible dream.

“…”

Mea glanced at the clock.
It was already a few minutes past her usual wake-up time.

“I knew it, it was all just a dream.”

Mea sighed with relief, but it was the first time she had dreamed something like that.

Suddenly, she heard the sound of the door opening.

“Onee-chan, are you awake? Hurry up and get ready.
If you want to compete with me, do it better.”

“…”

Chiyo then left Mea's room.

Mea then got up from the bed, but something felt off.
She felt tired and her body felt heavy.
After exerting herself, she finally managed to stand up, but at the same time, she noticed that her clothes were torn in various places.

“……..”

Not only that, the ring was now on her ring finger.
A beautiful ring, like a wedding ring.

One thing Mea knew for sure, everything she experienced was not a dream.

“So, that's what I went through.
Although it's hard to believe, …but both of you surely understand what I mean.
Can you tell me what happened?”

“…….”

“……”

Both of them couldn't comment much.
Indeed, they knew that what Mea experienced was not a mission, but for them, it was a new problem.

Suddenly, Chiaki smiled.
A frightening smile.

She looked at Kuro.

“Kuro-chan, …aren't you happy now that you have four wives? Do you really want to become a Demon God with 13 wives?”

Kuro was in trouble.
Big trouble.

“Aren't three people enough for you? I didn't expect you to be so shameless.
…so can you explain it to both of them?”

“Err…
let's discuss it later when we gather with everyone, okay?”

Chiaki sighed heavily.
She couldn't do anything.
And it was too late to do anything.

“Well…
I guess I have to hold back my anger here.
Understandable since I don't have the power to punish you here, but I'll have fun over there…
ku ku ku…”

“Your smile is truly terrifying, Chiaki.
Sometimes I wonder if you love me or hate me.”

“Of course, I love you, Kuro-chan, but I'm a victim of a man who refuses to make a decision.
You surely don't understand how I feel.”

“Your words make me sound like the most despicable man in the world.
It makes me a little sad.
Especially hearing it from my wife.”

“……?”

Meanwhile, Mea showed an expression of not understanding what they were talking about.
They were arguing, but at the same time, they were not.
That's what you call a lover's quarrel.

“Err…
can one of you-?”

Suddenly, Kuro held Mea's hand.
Mea didn't even see when Kuro stood up.

“It's okay if I explain it?” Kuro asked, turning to Chiaki.

Chiaki sighed as if she could already guess what was happening.

“Go ahead if you want.
If you want, you can have sex with her there until you're satisfied.”

Chiaki then left, leaving the two of them.

“Oh my, she's really angry.
I guess I've gone too far this time.”

“What do you mean?”

“It's nothing, really…”

“Huh?”

Suddenly, light emanated from under their feet.
The light turned into a magical circle.

Confusion appeared on Mea's face.
She felt like she was seeing something beyond her comprehension, which was magic.

“?”

But she realized one thing, the rings worn by Kuro and herself were emitting a strong light.

“Hold on, Mea-senpai.
We don't want to be separated during our journey.”

“Journey? Where to?”

Kuro smiled.

“To the world inside your dreams.”

“What?”

Before she could react, a bright light shone, making it difficult for her to see.
And when she looked again, she was already in an unfamiliar place she had never seen before.

She then turned to Kuro.
She was surprised to see that Kuro had changed his appearance.
He was wearing all-black clothing like in a game.
Meanwhile, there was no change in her own appearance.

 

“Welcome to the Celestial World.”

 

Meanwhile, behind the rooftop door, Chiaki slumped down.
She bowed her head while holding onto her knees.

 

She wasn't angry or sad, but her heart wasn't ready to accept what was happening.
The entangled relationship between Kuro and Mea had been evident for a long time.
It wasn't surprising that Mea became one of them.

 

“Kuro-chan, what do you really want?”

 

After school, Chiaki went home alone.
She wasn't with Kuro because she knew he was busy with Mea in CSO.

 

She glanced at the ring she was wearing.
With that ring, she could go to the CSO world just like Kuro, but she still didn't know how to do it.
Until now, she still relied on VR gear, but seeing Mea able to go to CSO without using VR gear proved that the ring could indeed do it.

 

“KHh….”

 

Chiaki gritted her teeth.
She was still angry because Kuro was with Mea.
After what happened, leaving the two of them alone was not the right choice.

 

“Why didn't I just go with them?”

 

But it was too late for regrets.
The most important thing was how to explain Mea's situation to Flamia and Ruko.
They might immediately kill Kuro for adding new problems.

 

“Ughh…
why am I remembering that Demon Harem? Ah…
I'm getting a headache thinking about it—uh?”

 

Chiaki was startled when she saw a luxurious sports car parked in front of Kuro's house.

 

“That's…”

 

Chiaki quickened her pace and immediately entered Kuro's house without knocking on the door.
She saw two pairs of shoes in front of the door.

 

Not long after, Ruko came and greeted her.

 

“Welcome, Chiaki-chan.”

 

“…I-I'm home.”

 

Ruko seemed happy as if something was happening.
Something indeed happened.

 

“Ruko-chan, could it be…”

 

“Yes, Mom and Dad are back today.”

 

“…..”

 

Kuro's parents.
Chiaki had only met them once.
From what she remembered, they were friendly and kind-hearted.
For some reason, they always traveled around the world, leaving Ruko and Kuro alone at home.

 

“Come in.
Mom and Dad want to meet you.”

 

“Eh? Uh, okay…”

 

Chiaki felt a bit awkward, but considering what Kuro's family was like, she had an uneasy feeling.

 

Ruko and Chiaki then entered the living room.
There, two people were sitting casually.

 

“?”

 

Chiaki was surprised to see their hands tightly holding each other.

 

The man looked young and handsome like Kuro.
He even reminded her of Kuro.
The woman resembled Ruko but in an adult version.
They looked similar, but it was normal.
Just like Kuro and Ruko, they were still a family.

 

+

 

“Chiaki-chan, it's been a long time.”

 

“Long time no see, Aunt Kuroyuki.
Uncle Yamato.”

 

They both smiled, while Ruko came with tea in her hand.

 

After placing the tea, Ruko and Chiaki sat facing Kuroyuki and Yamato.

 

“Don't call us like strangers, aren't we already a family?”

 

“Call us Mom or Dad.
We'd be happy if you do.”

Chiaki's face turned red with embarrassment.

“Don't worry, we already know everything.
About your marriage in another world, of course, we're aware of it.”

Chiaki's face grew even redder.
But Yamato's words explained everything.

“Don't fret, we're not angry.
It's just that I never expected the kid to have three wives at this age.
Well…
he has always been good at charming women like me and my father.”

“Huh?”

“Basically, they're ladykillers, but we're bound by tradition, so they can only marry their cousins.
If I recall correctly, didn't you manage to charm ten people?”

“That's still better than my father, who managed to attract 30 women.
I'm doing better.”

“Yeah, yeah, but in the end, you belong to me.
Aren't you happy, Yamato-niichan?”

Yamato smiled.

“It's been a long time since you called me that.
It really brings back memories.”

Their intimacy was clearly visible.
There was no doubt that they loved each other, but at the same time, this sight reminded him of Ruko and Kuro.

“Oh, by the way, where's Kuro? Didn't you come home together?”

Ruko also showed a curious look.

“Kuro is involved in a school activity.
He'll be coming home late.”

If he told them the truth, Chiaki worried that it would lead to bigger problems.
As far as he knew, Kuro's parents were not the type to come home without a clear reason.

Besides that reason, Chiaki knew that they were just like Kuro.
They were God Slayers.
The reason they traveled around the world was because of that.

They lived in different worlds.
That's what Chiaki knew.

“That's how it is.
He's probably charming another girl.
But it's okay, as long as he doesn't hurt you, it's not a big problem for us.”

“Huh…”

“Don't misunderstand, we're not letting him create a harem or anything.
But if you're all happy, isn't that better? Honestly, he made me…
Ouch…
don't pinch me, you know I'm just kidding, right?”

“I don't know, but my ears don't indicate that you're joking.”

Yamato looked at Chiaki and Ruko again.

“So, did A-um…
Dad and Mom come home to discuss that?”

Yamato shook his head.

“We didn't come home to discuss such small matters.
Do you think, Chiaki-chan, that we would dissolve your marriage? No, in fact, we support it.”

“Then?”

“We came home because we have something important to do regarding Kuro.
If left unchecked, he will become a more dangerous disaster than the Fallen God.”

“…”

Chiaki showed his confusion.

“Simply put, we're going to kill Onii-chan.” Ruko said with an innocent tone.
