Tokyo Revengers Omnibus, Vol. 9-10

Takemichi has returned to the present to find himself the first division leader of the violent criminal organization the Toman has become.

Takemichi himself?! To fix this present, he has to go to the past to confront the Black Dragons, a longtime rival gang with Toman. But he finds the only way he can save Toman from the Black Dragons is to keep the Black Dragon's leader from being killed... by his own brother?!
