I, Upper Moon Two, Reincarnated in a Shonen Manga

[New blurb, keeping the core Douma selfcest premise, mainly Bungo Stray Dogs. Upper Moon Douma is the top, no switching. He'll wreak havoc in the daily lives of hot-blooded manga protagonists]

After losing to the Demon Slayer Corps, Douma was deeply disappointed.

But the hellish judgment he'd expected never came. When he opened his eyes, he found himself lying by a riverbank, with the world around him utterly transformed.

The days of being Upper Moon Two were in the past. Now he was just a low-level employee at a company in Yokohama.

An ordinary person, albeit one with a few unusual tricks.

Douma wasn't thrilled that he couldn't eat people, but he began exploring this world with great enthusiasm.

For example, his company was actually a Mafia organization, and this world had people with supernatural abilities. They were far more impressive than the swordsmen of the Demon Slayer Corps.

For example, Yokohama was anything but peaceful, and his company seemed to have some unspoken history with the detective agency next door.

For example, the company's boss was more reliable than Lord Muzan, though that still wasn't enough for Douma.

Lord Muzan controlled him through his blood. This Mr. Mori didn't have any means of controlling him at all...

A change of leadership shook the Port Mafia, and the other two ability-user organizations were shaken as well, wary of the new boss.

His name was Douma. His ice-type ability seemed perfectly ordinary, but in his hands it unleashed terrifying power.

As the new boss, Douma was quite pleased. He ran the organization like the Eternal Paradise Faith, only this time Lord Muzan wasn't there to hold him back.

One day, Boss Douma was strolling by the river when he came across a boy crouching beside some bushes.

He put out the cigarette in his hand and looked at the boy's all-too-familiar hair. Then his gaze moved down and landed on something even more familiar: the boy's cult leader robes.

Hearing footsteps, the young cult leader turned around and looked at him. His eyes widened slightly, shining with the exact same light as Douma's.

"You're me," he said with certainty.

Boss Douma smiled. "You're right."

The Port Mafia carried on as usual. Its new boss was every bit as capable as his predecessor, and even gentler in his methods.

Many people said Douma might be a good person.

Dazai Osamu didn't agree or disagree.

If someone who tried to gnaw on the limbs of his own kind could be called a good person, then Mr. Mori might as well become a Buddha on the spot.

What was this supposed to be?

Yokohama's Hannibal?
