The Book of Yokohama

When a shadowy informant reveals the existence of a reality-warping ability user known as "The Book" operating within Yokohama, the heroes of UA High School are thrust into a complex and dangerous mission. Led by Eraserhead and All Might, a team of five students, including Midoriya, Bakugo, Todoroki, Uraraka, and Iida, is sent to observe the situation and gather intel on the individual possessing this unprecedented power. However, the mission takes an unexpected turn when they discover "The Book" is none other than Atsushi Nakajima, a young man struggling to control his volatile ability and caught in the crossfire of Yokohama's powerful underworld organizations: the Armed Detective Agency and the Port Mafia.

As the students navigate the city's intricate web of power dynamics, they must learn to balance their own heroic instincts with the delicate balance of forces at play. They must observe Atsushi, understand his emotional triggers, and gather information without jeopardizing their mission or the fragile peace of Yokohama. The stakes are higher than ever, and the fate of the world hangs in the balance as the students face a challenge unlike anything they've ever encountered before.
