Ayashimon, Volume 1: I'll Play with You, Punk (Ayashimon #1-7)

Maruo always wanted to be like the characters in his favorite manga. Unfortunately, his training efforts have paid off a little too well. Now he breaks everything he touches, can’t find a job, and wins every fight too easily. However, when he encounters a girl being pursued by a group of thugs who turn out to actually be monstrous ayashimon in disguise, it seems like his real-life manga story is about to begin!
