Deadman Wonderland

Interesting anime about a boy framed for murder of his classmates and is sentenced to be executed at a wonderland park that employs convicts in deadly sporting competitions for the public. He struggles to survive and slowly in the process discovers his hidden powers….

Story clearly has my attention and i think ill see this anime through its first season. 

Update:

The suspicious activities of the Wonderland hold special battles between the deadmen that have been exposed to the branches of sin. The ability of individuals lie in their blood to form special abilities and projectiles when they bleed out from self or external injuries.
