Rooster Fighter (Manga) Vol 01 (Mature)

The neighborhood cock of the walk is more than just an ordinary rooster-he's humanity's greatest defender! His opponents may be ten stories tall, but nothing is bigger than his stout heart and his fearsome, earth-shattering cry-cock-a-doodle-do! For older teen audiences. Viz Media Llc
