Plot Summary:
Ganta Igarashi has been convicted of a crime that he hasn't committed, and sent to a new, privately owned and operated prison, where the inmates are the main attraction in a modern day twist to the gladiatorial coliseums of ancient times. Throw in a healthy dose of weird little girl, some new-found super powers, and a little conspiracy theory, and you have Deadman Wonderland.

Deadman wonderland is an awesome manga in my opinion. It has a great storyline, good battle scenes, and some interesting characters. Still in early stages of the plot, but its great so far.
