Am I the Only Cosplayer Here?

[Complete. Extras updated from time to time] [Check out my ongoing story next door, "Tentacles Have Been in Sukuna’s Belly Too": The loneliness born of absolute strength. The ones who taught him to love were, tentacles, and the eggs tentacles left inside his body.]

[Coming soon: "Restricted Fiction, but Infinite-Flow Werewolf". Blurb at the very bottom.]

Fengya, a cosplayer and rabid fan of Dazai, transmigrates the day before attending an anime convention, right after finishing his makeup test.

At first, he doesn’t realize he’s transmigrated. Looking at the white hall full of four Chuus, five Gojos, seven or eight Dazais… and all kinds of popular and obscure characters, he can only marvel at how accurate everyone’s costumes and makeup are.

Then a System prompt rings in his mind:

[Game start. Players, do not reveal that you are cosplayers.]

Fengya: ???

…

This is a game of Werewolf. Almost everyone is an original character from a different IF route. Each round, the players are sent to a different scenario, and then they vote when it ends.

Fengya casually draws a card and reads the scenario:

[Taisho era. A tyrannical father (Gojo), a mad mother (Gin), a gloomy younger brother (Dazai), and a sister on the verge of breaking (Tomie). As the eldest brother, you must work hard to maintain a harmonious, happy family.]

[Jujutsu world. The opposing team consists of jujutsu sorcerers (Fyodor, Enmu, and others). Your teammate is the Special Grade cursed spirit, Shinigami Conan. There are three Dazais in one world, so do your best to keep the world from going nuclear!]

[Detective Conan world. It’s just ABO, that’s all…]

Fengya grits his teeth and does his best to invent a plausible backstory for himself as an IF version of Dazai.

But in the end, he can’t compete with the other Dazais. After several rounds, he’s pushed to the brink.

“Your eyes are different from ours.”

Just as the System is about to declare him the loser, Fengya shuts his eyes and gives up:

“Is being Dazai really such a happy thing?”

The undercover player outs himself!

“I used to think life was painful too, until I found someone I loved. Unfortunately, he’s gone now. But luckily, the game told me that the person I love is here.” Fengya points with his eyes still closed. “I know it’s ridiculous to fall in love with an alternate version of yourself. Vote me out. I don’t want to hurt you.”

“What if one of you is my wife?”

He reaches out.

All the Dazais take a synchronized step back. All of Chuuya’s counterparts wear strangely complicated expressions, while the other characters either grab some popcorn or watch the show.

…

Fengya: QAQ

He doesn’t want to lose the game, but his Dazais, his fictional wives, please don’t look at him like that

Why have you suddenly stopped suspecting me and started accusing each other of being out of character instead?!

I’m really not a pervert!!!

Ongoing story next door: "Tentacles Have Been in Sukuna’s Belly Too"

It’s a tentacle, and its dream is to eat the strong.

It knows that only the strongest tentacles deserve to have the strong, so it studies hard. Barbs, suction cups, injections, laying eggs: it masters them all. Even its poison comes in doses ten times stronger than usual.

But unfortunately, the prey it has its eye on is super, super, super resistant.

The tentacle doesn’t know what he’s resisting.

Isn’t this supposed to be fun?

…

A thousand years later, they meet again, and the tentacle still wants to eat.

But what greets it is [Malevolent Shrine]. The Domain expands, a mountain of corpses and a sea of blood, bones glinting fiercely. The man remains high above it all.

The tentacle is sliced into 108 pieces.

But it’s happy.

“I knew you were sentimental. You like familiar places and familiar food.” The newborn tentacle writhes around him and snatches up the remains on the ground. “But sashimi is off the menu.”

“You need to take good care of the baby and get some exercise in moderation.” It blushes. “I’ll make sure you’re well fed!”

Sukuna: “…”

Coming soon: "Restricted Fiction, but Infinite-Flow Werewolf"

Content reviewer Wang Qingshui transmigrates.

The System gently explains: [This is Green River Infinite Flow. We’ve detected an NPC from a restricted-fiction scenario who has slipped into one of our instances. To clean up the community, we hope you can find them.]

Wang Qingshui: “Got it. Like Werewolf!”

…

Wang Qingshui arrives at the first instance: a closed-off academy for people with special abilities, where the strong rule and all kinds of species abound. The System begins its introduction:

NPC No. 1 is a teacher, impeccably dressed in a suit and looking refined and chaste, but secretly a little addicted to some spicy hobbies.

No. 2 is his roommate, a bad-boy hunk with hard snake scales on his profile, who occasionally sprouts… two tentacles.

No. 3 is the school doctor, a warm and caring healing-type powerhouse with two personalities and two abilities. His side gig is hypnosis, and he likes to leave psychological imprints on his patients.

No. 4 is a seemingly normal, top-ranked campus heartthrob in gold-rimmed glasses, who just occasionally pulls out slippery, sticky tentacles…

…

Wang Qingshui interrupts the System: “Wait, does every instance really have only one restricted-fiction character?”

System: [That’s right!]

[And Host, be careful. The creators of these instances are usually very hostile to content reviewers. You absolutely must not be discovered!]

Wang Qingshui: …

So I’m the undercover one.

But later, the secret gets out, and everyone learns that a content reviewer has entered the instance. The alarm sounds, an urgent meeting is called, and all the NPCs are summoned to vote on who the undercover player is.

Wang Qingshui is incredibly nervous. Compared to this whole bunch of perverts, he’s sure he’ll be found out in a heartbeat.

Instead, the NPCs start fighting, attacking each other and eliminating their rivals.

“Is no one going to ask me any questions?” Wang Qingshui trembles from the sidelines.

The fighting stops. Everyone turns to look at him in unison, then shakes their heads in unison. “You?”

On the meeting room screen, the instance records show Wang Qingshui climbing into someone else’s bed in the middle of the night, being held all night, his cheeks flushed, and clinging to the other person reluctantly as he murmurs, “You… really aren’t going to do anything?”

Wang Qingshui: “…QAQ” That was all to find the restricted content!
