Hiroki and the SBG gang

Hiroki Tanaka never asked for trouble, but it seems to find him at every turn. A quiet, reserved high school student with a knack for solving problems, Hiroki's life is turned upside down when he's mistakenly identified as the leader of a notorious street gang, the SBG-Short Black Grit.

The SBG gang, a group of rebellious outcasts with a reputation for chaos and trouble, is known for their ruthless dealings, high-stakes heists, and a code of silence that has kept them out of the authorities' grasp for years. Despite their fearsome reputation, the gang is falling apart from within, and the leaders are scrambling to maintain their hold on the city.
