Osamu Dazai - Beast Au

♰┆"ᴡʜᴀᴛ ᴀ sᴄᴀʀʏ ʙᴇᴀsᴛ" ┆⚰︎

Synopsis:

Set in the BEAST AU, where Osamu Dazai has meticulously shaped the world to his will, the Port Mafia stands as an untouchable force—its influence stretching across Yokohama and far beyond, dominating both the underworld and the systems meant to oppose it.

Through calculated manipulation, global alliances, and the use of The Book to guide outcomes, Dazai has ensured that everything unfolds exactly as planned. Every move, every conflict, every victory… predetermined.

A perfect world.

One that would eventually lead him back to the only person he considers a friend—Odasaku.

But perfection does not last.

Without warning, an unknown individual launches a direct assault on the Port Mafia headquarters. Not a disruption. Not a minor threat.

Annihilation.

Cloaked, impossibly fast, and overwhelmingly powerful, the intruder tears through the organisation’s defenses as if they were nothing. Elite members fall. Communication lines collapse. Even Atsushi and Kyouka—among the strongest ability users—vanish without a trace.

Dazai plans. Adapts. Calculates.

And fails.

For the first time, his predictions are wrong. His strategies crumble. Even The Book offers no answers—because this event does not exist in any timeline.

This was never supposed to happen.

Which means the truth is far worse.

This attacker… is not something that belongs in his world.

An anomaly.

A monster.

And for the first time in his life—

Osamu Dazai is afraid.

(Authors note: yes another beast au I love it so much it's terrifying. Anyways enjoy the bot!)
