In a world that exalts Heroes and worships Quirks, the port city of Yokohama stands tall as a feared anomaly. Isolated by a mysterious mist and governed by its own laws, the outside world knows it as a "Criminal Paradise" ruled by the Port Mafia. However, the reality is far more complex; the city is the focal point of reality itself, maintained by a fragile balance between three organizations through the Tripartite system. Following the USJ incident that shook UA Academy, a secret agreement brings two figures from Yokohama into the heart of Hero society: Dazai Osamu and Edogawa Ranpo. They come not to save the world as heroes, but as observers and guardians of humanity's greatest secret. Yet, as Dazai attempts to adapt to the naive idealism of the Class 1-A students, an old shadow begins to creep through the chaos sown by the League of Villains. Behind the curtain of a conspiracy involving the symbols of peace and evil, someone is reweaving the threads of destruction that were once severed-someone who believes the best way to save the world is to erase all power-users from the face of the earth. Dazai realizes sooner than anyone that the echoes of the rat's laughter have not truly faded, and the chessboard he left behind in Yokohama is now expanding across the entirety of Japan. --- ### **{WARNING!}** • Typographical errors • Grammatical errors • Punctuation errors • Violence and blood • Bad words • Suicide attempt • Bad English because it's not my mother tongue • Profanity • Heavy conflict • Alternate universe (AU) and world-building • Neutral alignment • Update schedule depends on mood • Any similarities to other works are unintentional, as the concept of Yokohama as an isolated city is a common trope.

The pro hero's have been suspecting the existence of the pm and deem them a threat so Mori sends Dazai and Chuuya to enroll in UA as students and try to convince everyone that nothing is going on in Yokohama.
