Get Backers X-2 - Black Mage

Third in the GBX-2 series. Well, gee - who else would be the evil stabbity black mage besides Akabane? ;) Plus, he has that evil fascination with Ginji, who's the white mage, and a weird hat... it all goes together pretty nicely.

Can't you just picture him saying "Meteor~ <3"? I've dubbed him "Bloody Waltz".
