Little Sister Simulator, but Every Route Ends Badly

[Currently writing "Teacher, Is This Really a Legitimate Cosplay Commission?" with Gojo as the pairing, please add it to your favorites QAQ]

I'm the legendary BE magnet. Whenever I play a romance game, no matter how pure and sweet the route is, I always trigger a bad ending.

After turning a game with one hundred percent sweetness into an ending where one person died and the other went insane, and scaring off a whole crowd of fluff lovers, I was permanently banned from playing by the game's official account.

Today, after another failed attempt to kill himself, my bandage-wrapped older brother bought me a game of my very own to cheer me up. It was called [Little Sister Simulator].

This game only has sibling routes.

He said that since romance games always end badly for me, I might as well take the family route. Besides, fictional siblings are all practically on the edge of incest anyway.

After telling him how gross he was, I started the game, mostly out of boredom.

But he didn't tell me it was a live-simulation game. Entering the game meant being born into another world, and losing my memories!

And this bastard was livestreaming my gameplay to make money!

Just you wait! Once I beat the game, I'll definitely...

[Welcome to Little Sister Simulator. Game start.]

[Winter's Hidden Heart] Older Brother No. 1: The Frail Twin Sister of the Six-Eyed Divine Child

You and your six-eyed older brother were born at the same time, but you were forced to bear the curse. Whenever you get close to him, it drains your life, leaving you with only a year to live.

You grew up apart and had never met.

You bore the curse, while he knew nothing about it.

You instinctively wanted to get close, but could only be forced to stay away.

You overcame secrets and curses, and defied the limits of your lifespan.

He treasured you, and you promised him that you would live to be a hundred.

But then you learned how his story would end.

You chose to sacrifice yourself, becoming his weapon in the fight against the future.

He held the birthday cake he had made with his own hands for the two of you, only to receive the news of your death.

[Game Over]

[Summer in Reverse] Older Brother No. 2: When My Brother Wanted to Kill Our Family, We Switched Bodies

"Come on! If you so much as lay a finger on me, I'll run around naked in your body!"

Gojo heard from Yaga that Geto had recently been muttering things like "monkeys" and "meaning" all the time. He might be depressed, so Gojo should keep an eye on him.

When he went to check on him...

"Whoa! You're so handsome! Do you have a girlfriend? Do you? Do you?" The other person popped up all around him like a gopher.

He really wasn't acting normal.

Your brother became you and lived an ordinary life. You and your adorable friends helped him heal, and he found the value in protecting ordinary people again.

But you were diagnosed with a terminal illness and died on the day he said at your graduation ceremony that you were also the reason he became a jujutsu sorcerer.

Game over.

At last, the game was complete. Every route, without exception, ended in a bad ending.

Your bandage-wrapped brother wore a smug grin. You knew he'd set you up.

You beat him up and refused to speak to him ever again.

What a piece of trash!

If only the brothers in the game really existed.

As you thought this, the white-haired, blue-eyed boy and the black-haired boy with a topknot, all the brothers from the game, appeared by your side.

"I'm sorry, Aoi. Don't be mad anymore~ There's a second game now, so let's play it together." Your bandage-wrapped brother invited you just then.

Hmph~

You'd rather cuddle up to your new brothers. You didn't want to talk to that scumbag.

Your bandage-wrapped brother watched you, his eyes growing darker day by day.

There's no way a mere virtual character could take his place...

:

You caught up with your new brothers and were happy every day.

But what you didn't know was that after you died, every single one of them...

went insane.

"The six-eyed older brother relived every little memory of you each day, keeping them all firmly in his heart. Even the slightest blurring of a detail would drive him mad, so he spent his whole life immersed in his memories of you."

"The black-haired older brother with a topknot thought countless times about cursing you and turning you into his shikigami, so you could be together forever, but he couldn't bring himself to do it."

Now, at last...

"I've found you again."

He would never let you leave again.

★ These are all sibling bonds, pure and real, between actual siblings! A massive sibling love triangle × a crematorium for the little brat XD

"Teacher, Is This Really a Legitimate Cosplay Commission?"

While idly browsing posts, I came across a cosplay of my favorite, Teacher Gojo, and was instantly blown away by the cosplayer's beauty on the other end.

I immediately booked a cosplay commission with the teacher to heal my battered, overworked soul.

I went to the station at the time we'd arranged to meet and pick her up.

In the crowd, one white-haired person wearing sunglasses stood out. She had to be cosplaying Snake from One Piece!

I strode over confidently. "Hey! Honey~"

Of course, I made sure I had the right person.

After she confirmed it, I took her straight to a hotel, where we took a ton of pictures and vlogged to remember the day. Not suitable for children, that is. (Strike that.)

The teacher was incredibly convincing! From her height to her makeup, hair, and aura, she was exactly like the real 5t5!

How could a girl be so tall?

"Teacher, your wig is such good quality. It won't come off even when I tug on it!"

"It's dyed hair~"

"Teacher, your foundation sits so perfectly. Your skin looks like you were born with it!"

"I'm not wearing any makeup~"

"Teacher, can I get a link to your colored contacts? They're so realistic!"

"They were custom-made just for me~"

Wah, the teacher was so dedicated. She'd even learned to do a masculine voice for the sake of accuracy. I love her so much T^T

One part of the video involved unbuttoning a shirt halfway and pinning someone to the bed, but the teacher was a girl, after all, and I didn't want to make her uncomfortable.

But the teacher said we could edit her body in post, and to keep the mood from being ruined, she blindfolded me.

It turned into a blindfolded bed-pinning scene...

Teacher, don't do this. You're really going to turn me gay. ()

Come to think of it, when did I start liking Teacher Gojo?

That's weird. I can't remember.

Back in his days at Tokyo Jujutsu High, 5t5 met a strange girl.

She came rushing at him, shouting weird things like "System," "affection level," and "target to win over."

At first, he thought she was just an internet-addicted girl who'd played too many dating games.

They went through a lot together, and as time passed, his feelings for her grew stronger and stronger.

He even promised that they would get married after graduation and stay together forever.

But then, one day, she suddenly said she'd completed her mission and had to return to her original world.

So dating games really were real?

The girl had appeared out of nowhere, then left just as suddenly.

He spent many years alone, in a world without her.

Until one day, he arrived in an unfamiliar world. There were no curses everywhere, and his picture was even displayed on a screen on the street.

Then that girl appeared again.

"Teacher! Let's take some pictures of us kissing and hugging, then edit them into a vlog!"

Sure...

This dating role-play game was unexpectedly fun.

"Teacher, can I kiss you? I mean, on the face. Just the face!"

This is bad.

How should he tell her that anywhere but her face was fine, too?

"Teacher, thank you. I had a lot of fun this time, so the commission ends here.

He smiled and grabbed her wrist. "No..."

The game couldn't end so soon.

And she couldn't leave again.

Because this time, I was the one in control of the game.

[Bonus Scene]

Kashima Yuu, known as the prince of the school, became a cosplayer without hesitation after realizing she was destined to cosplay as a man.

Mainly because it let her skip club activities. Besides, if she told Hori-senpai she was doing it to hone her acting skills, he wouldn't question her.

One day, Kashima accepted a commission to cosplay as Teacher Gojo. But when she arrived at the station, the client was nowhere to be seen.

Just as she was about to contact them, someone in the same line of work hit her from behind and knocked her out.

When she woke up, Hori-senpai was there.

"Hori-senpai, this is scary. Are people in the same line of work really resorting to this kind of cutthroat competition now?"

Theme: May you and the person you cherish be reunited one day.
