Story: I thought this was pretty average, nothing special but enough too intrigue me to keep watching. That powers are cool and the world itself is actually pretty interesting.

Sound:6/10 the sound is very similar to the art ...

Art: 8/10
The character designs are all unique, which helps if you're like me and can't remember names. I especially applaud this show for its flawless integration of 3D with 2D designs. The sparse use of 3D really served ...
