It's Agito from Air Gear.
With lots of chains and symbolism that you can make up as you please.
His skates got cut off, but whatever, not a big loss.
I drew this during class because school is boring as heck. I need something to do to keep me awake during class right?
Maybe if I'm really bored, I'll color this one day. Maybe.
Agito belongs to Air Gear and its creators.
