Amalgam of Distortion.
A youth named Rokumichi got run over by a train and half his body was destroyed. The other half was altered with unique genes that turn him into a bone manipulator.
In order to survive, Rokumichi must join an organization that hunts those who turned him into this monster, as well as the monsters they've created.
I like it for the art, to be honest. It manages to be very creepy while also having its unique notes, for a battle shounen, especially given the luck [or lack thereof] of creating new 'successors' for Naruto & Bleach since they ended.
Unfortunately, getting a translation has been hard, so I've been reading it raw for a while. The only other language that's even been keeping up with it is Indonesia of all things!
