Evolution by IIChaosII reviews
Sawada Chiyohime had seen many strange things throughout her life. Being the younger sister of the boss of the greatest Mafia famiglia in the world assured it. Especially when the mafia destroyed the laws of physics time and time again. So, really, a walking talking octopus that destroyed 70% of the moon was not that big of a deal. Didn't stop her from being assigned to kill it.
