Top-Tier Star Boy Band Members Are Still Using Superpowers to Beat Each Other Up Today

Blurb:

Hoshino Ren was an utterly ordinary college guy, the lonely king of the only-child club. That is, until he transmigrated!

Not just once, either. He transmigrated through a whole string of worlds!

In Beika Town, he became the babysitter for the "Shinigami Elementary Schooler": "There's only one truth? I'm innocent!"

At Jujutsu High, an unscrupulous teacher studied him like a pet: "Gojo Satoru! Put down my snacks! And me, too!"

In Yokohama, a bandage-wrapped lunatic dragged him off to die together: "Mr. Dazai, if you're jumping in the river, get in line. Don't cut ahead of my transmigration!"

At Karasuno's volleyball court, he was forced to be the "emotional stabilizer": "Hinata, Kageyama, if you keep arguing, I'll stuff the ball in your mouths!"

Adrift in another world, his circle of brothers keeps growing.

Conan thinks he's "mysteriously reliable," Itadori calls him "my best bro," and Naruto is convinced they're "bonded for life." Hoshino Ren: Thanks for asking, I just want to go home... Or at least stuff all my bros into a suitcase and take them with me?

But after the high comes the fall, and the world starts going haywire. When the final boss appears, Ren looks at the bizarre bunch of brothers behind him and takes a deep breath. "Brothers, let's get them together!"

They finally did it! Except... Hoshino Ren: Help! This savior's role is a hot potato, and it comes with an arranged marriage?

Warning: Original settings and plot holes abound. The final pairing is undecided.

My other ongoing novel: "Dazai: What's It Like to Be Conquered by the Strongest?"

When Dazai and Gojo are bound by a curse, the two strongest are forced to sign the worst contract in history: shared pain.

Gojo crushes his sunglasses. "Mackerel, if you jump into a river, I suffocate. How is that fair?"

Dazai smiles faintly. "Why don't we die together, Mr. Gojo? It's a win-win."

Shoko takes a drag on her cigarette. "The strongest chokes to death on Kikufuku? That's a joke that'll keep me laughing until next century."

Mori suggests, "Get married. Split the medical bills."

Neither of them is easy to handle.

He teleports over and crushes his roll of bandages. "Try killing yourself again, and I'll let you experience what 'No Longer Human' really means."

He hands him coffee made with dish soap. "Want to try some? Maybe it'll clean out that brain of yours stuffed with sweets."

On the nth day of tormenting each other, the curse bizarrely upgrades to shared pleasure.

When fingertips brush skin, when panting fills the night, their senses flare together, turning them into a long-distance couple by force.

"Scum... get your hands off me..."

"You moved your leg first, liar."

When hostility turns to flirting and murderous rivalry becomes intimacy, they discover the ultimate secret of the curse: pleasure doubles during sex.

"Admit it. You're enjoying this."

"You're the one panting like you're more into it than I am..."

When a curse user detonates a blood curse, he howls, "Become one! You're made for each other!"

They fire bullets and cursed energy together, exchanging glistening, tearful looks in the light of the explosion.

"Welcome to hell, partner."

"...Likewise, scum."

This unsolvable curse is the eternal paradise that addicts chose with their own hands.

And they're willing to make each other an addiction they can never quit.

Coming next:

"On the Compatibility of Sorcerers and No Longer Human"

The entertainment industry is in an uproar.

A stunning boy band called "404" bursts onto the scene, its members' backgrounds a mystery:

Gojo Satoru, whose stage presence is a nuclear bomb, with the side effect that his cursed energy can go berserk and flip a gymnasium upside down.

Dazai Osamu, world-weary and languid, whose passive skill, "No Longer Human," is the perfect answer to anyone who can't stand Gojo Satoru.

Gin, more practiced at cleaning his gun than thrusting his hips, looks at his teammates as if they're targets to be eliminated.

Kakashi, with a privacy screen for his Make-Out Paradise, always dances on the edge of saying something too explicit to air.

Oikawa Toru, the embodiment of volleyball resentment, who routinely bellows, "Give me back my training court, you bastard!"

Their manager, one step from a nervous breakdown, slams the table and roars, "I signed you to do idol work, not use your superpowers to demolish buildings! Especially you two!"

His trembling finger points at Gojo Satoru and Dazai Osamu.

"Gojo, get your cursed energy under control! Dazai, starting today, you're his exclusive 'nullification' partner! Twenty-four hours a day, no more than five centimeters apart! For world peace! Stick together!"

The whole internet erupts. Aren't those two famous rivals from Tokyo University?

Back then, one blasted a hole through the laboratory building with cursed energy, while the other showed off his nullification. Whenever they met, they traded insults:

"Are Dazai-chan's bandages wrapped around his brain?"

"Are Gojo-kun's Six Eyes just for show? Can't you see how annoying you are?"

In front of millions of livestream viewers, Gojo throws an arm around Dazai and pins him hard against the backdrop wall. His silver hair brushes the bandages, his breath hot.

"Dazai-chan's 'nullification' is still so infuriating, yet reassuring."

The comments explode:

Is this wall pinning just a way to settle a personal grudge?

That sexual tension is killing me!

Rivals turned wives?

Gin silently cleans his gun. "Keep pushing this ship and I'll shoot you."

Kakashi walks by holding Make-Out Paradise. "Paid content. Not suitable for kids."

Later...

One of the interview questions reads: "What's the one thing you most want to do to the other person?"

Gojo stares at Dazai's lips and tugs his tie provocatively. "Make you cry and beg for mercy."

Dazai takes the opportunity to wind his bandages tightly around Gojo's throat, straddles his waist, and smiles. "Funny... I want to see you suffocate."

Core theme: Unity is strength.
