Kuro Rekishi Daikessen

Jou Shishime gets into fights on a daily basis, and is feared by all those around him - even to the point where he can intimidate a crying child into silence. One day, his usual opponent gains special powers from another dimension, which is enough to drive Jou to despair... But after he finds out about the existance of a neurotoxin called "Kurorekishin" (Darkpastin), he begins recalling his dark past. The past he'd rather not remember... Memories he'd like to erase.... He'll turn them all into his strength and power!
