I Dominated Shonen Manga After Awakening a Strange Technique

[After playing a medium in the jujutsu world, I kicked the bucket]

"Why did you come to Tokyo Jujutsu High?"

"No idea. I heard there were no academic classes, so I came."

It's got a weird name: True 7, Brain 3.

[As a hostage in the Sengoku era]

He starts out with a sickly debuff and is sent to the Tsugikuni family as a hostage. Luckily, he becomes good friends with the heir, Senjuuro.

The Tsugikuni family falls into turmoil. Suzuki Sen persuades Senjuuro to flee, then turns around and joins the Demon Slayer Corps.

After working his way up to the top and helping run the Demon Slayer Corps, Suzuki Sen has barely had time to enjoy himself when he runs into a certain Demon King.

Suzuki Sen: ...Don't come any closer!

Later...

Suzuki Sen: Come on! Aren't you supposed to be strong?

After successfully kicking out the Demon King and taking his place, Suzuki Sen immediately gets the Infinity Castle. The three-hundred-year construction plan for Infinity Castle Ltd. is now underway!

It took Suzuki Sen three hundred years to go from sickly hostage to ruler above all demons.

His subordinates are great in every way, except that there are too many lunatics and undercover agents. After thinking it over, Suzuki Sen decides to run away.

And then all his subordinates go crazy.

[After maxing out my main account, I decided to join the plotters (hee hee)]

One phone call later, Suzuki Sen returns to Yokohama to take over the family business and officially begins dealing with Yokohama's other factions as the new leader.

Yokohama seems peaceful for now, but beneath the surface, tensions are rising.

Everyone is fighting over a boy whose ability is "Tiger."

Suzuki Sen: Tiger? I actually know a tiger!

Sorry, wrong series. (cough)

A mysterious power by the sea has spent years trading, but never cooperating with anyone. The previous leader, Edward, was British, easygoing, and ruthless. As soon as the new leader, Suzuki Sen, takes over, his very different approach makes the other factions wary.

The Tsugikuni twins, with their terrifying swordsmanship; the villain with seven-colored eyes and powerful ice abilities; the new faces appearing in [GA]. Each is more ferocious than the last.

The leader, Suzuki Sen, is a demon in every sense of the word.

The Three-Part Structure begins to collapse, and all sorts of incidents break out. When various ability users come to rescue the tiger boy, Suzuki Sen chooses to bring out his Demon King main account. So they've got numbers on their side? He's got numbers of demons on his!

After being strapped to a bomb in the street and caught in a mutual suicide attack, Suzuki Sen, leader of [GA], is gravely injured and disappears.

The Hunting Dogs appear early, the plotters gain a new collaborator, and [GA], leaderless, goes completely off the rails.

"Create a world that reflects my heart."

The final season of the crossover series The World of the Heart is here. Continuing the previous season's villainous approach, the protagonist Suzuki Sen teams up with the plotters, and Dazai's right-hand man gets even stronger, going on a rampage across Yokohama.

There's no way the revival round can end in victory.

The privileged are all thrown into the Book.

A world with only the jujutsu sorcerer system becomes Jujutsu Kaisen. A world with only the man-eating demon system becomes Demon Slayer. A world with only the supernatural ability system becomes Bungo Stray Dogs...

Dazai, the ordinary world you wanted is here!

* Xiao Sen's journey through time and space. You probably don't need to have read the Jujutsu Kaisen arc to follow the Demon Slayer arc. The first trilogy is on the side of justice, while the second and third trilogies are on the side of injustice.

* About Xiao Sen: A standard-issue Celestial Dragon, a legendary punching bag, and a conceptual deity in the later story. In his first and third lives, he's a charming mixed-blood; in his second, he has a more classical East Asian appearance. He's a chaotic, morally ambiguous fun-seeker.

* A patchwork setting with randomly generated author-created details. Mixed-blood headcanons are standard procedure (yes, really).

* Centered on the protagonist. There will be one-sided crushes. Please don't ship random pairings (canon pairings are fine).

* The card-opening game includes the mechanics featured in the livestream so far, such as extra packs, the roulette wheel, forcing a marriage...

~ Advertisement: A must-read for obsessive fans. The ongoing gen story, Reincarnated in Another World as a Gojo Fan, has content warnings below the blurb.

Kitashirakawa Sakuichi is a well-known fan in his circle. No one can match his output or the intensity of his devotion.

Then one day, he tripped and died on the spot.

The good news: He transmigrated into an anime world!

The bad news: It's not the anime he ships, and it's the Demon Slayer series, which he hates!

But there's more good news! His predecessor cut down the Demon King, but the Demon King struck back as he died, and Sakuichi woke up as the new Demon King.

What's the point of being a Demon King? Despairing, Kitashirakawa Sakuichi wants nothing more than to die. He sits outside, waiting for the sun to come out so he can hurry up and reincarnate.

Then he sees several particularly ugly monsters roaming outside. A few people hurry over and use all kinds of techniques. Panting, they say, "Finally, we've exorcised this cursed spirit."

Cursed spirits?

Kitashirakawa Sakuichi (standing up) (smiling), one hand gripping each of them, gently asks, "Tell me, are there jujutsu sorcerers here?"

The jujutsu sorcerers nod frantically.

The newly appointed Demon King smiles even more brightly.

Fuck, he'll tough it out until the modern era if he has to. He has to be more tenacious than Muzan if he wants to see his favorite!

-

Even a Demon King nearly fell victim to the plot. Luckily, Kitashirakawa Sakuichi had seen it coming and pulled out all the stops, barely managing to survive.

In the winter of 1989, the Demon King, returned to the light of day, crawls out of the deep sea and throws his head back, laughing with blood-red eyes.

According to the story, the Six Eyes prodigy of the Gojo family will be born that winter, shocking the jujutsu world. At the same time, cursed spirits will rapidly grow stronger, and everyone will turn their attention to the newborn prodigy. Assassins won't give him a moment's peace.

At the beginning of the new year, a red-haired young man knocks on the Gojo family's door.

He shows them a contract and cheerfully says that a previous head of the family sold the prodigy to him.

Then he gets turned away at the door.

An hour later, the bruised and battered family head brings Kitashirakawa Sakuichi to meet the prodigy.

Kitashirakawa Sakuichi looks at the child, who is clutching a toy and gazing at him curiously. His fist clenches beneath his sleeve, and he stops breathing.

At last!

Excitement shines in his eyes.

This time, he'll guide the prodigy step by step to a peak no one can surpass!

In March, a new Jump manga hits the stands. A previously unknown name bursts onto the scene: Reincarnated in Another World as the Demon King in a Demon King's Body. It shoots up the rankings in its first week.

Praise for the author's striking art is accompanied by doubts about the protagonist.

The forum splits between skeptical insults and fervent declarations of love.

Finally, after the manga's third chapter, the two camps reach a consensus.

[I wanted to watch the protagonist slaughter everyone and destroy the world, and you're telling me he spent all this time keeping his head down just to raise a kid?!]

Little Satoru wants to go out and play. Kitashirakawa Sakuichi waves a hand: "Go!"

Little Satoru wants to study. Kitashirakawa Sakuichi waves a hand: "Study!"

Little Satoru wants to get stronger. Kitashirakawa Sakuichi waves a hand: "I'll train with you!"

Little Satoru... Your little Satoru has unlocked: [Strongest Jujutsu Sorcerer] [Academic Prodigy] [Study Abroad] [World Traveler] [Fluent in Eight Languages] [Everyday Skills Maxed Out] [Ruler of the Jujutsu World]...

"I don't give a fuck who the bright moon shines on. I just want him hanging high in the sky. Whoever gets in the way of that, I'll cut them down."

* Demon Slayer content: 10%. Mainly Jujutsu Kaisen, with a little Bungo Stray Dogs. There are forum-style sections in the main story.

* Content warning: The protagonist is an obsessive fanboy. He can be a coward or stand his ground, and his personality changes a little over time. Around WTW, he remains in human form (hopefully that stays true ^^).

* Sakuichi is a dad (gestures). Not literally his dad, more like a devoted mom-fan (nods). He's focused on raising Satoru.

[The protagonist hates everyone except WTW. Every character automatically starts at -99 favorability. The protagonist is a deranged fanboy.] (Highlighted) (Highlighted) (Highlighted) (please)

[The author doesn't often reply to comments, but reads them all (nods).]

[The plush dog on the protagonist's character card is Sakuichi... (looks away).]

[Leave a comment to get the commissioned Gojo fan art from the character card. See the author's profile for details.]

-I dedicate this story to Gojo, wishing you a happy birthday in 2025.
