So this is a bit of a companion piece to this one. He is Naberius, Marbas's canine counterpart, and one of my favourite characters in Tale of Outcasts. He was the only one (other than his contractor, Diane Blackrose) to catch Marbas off-guard, so his cool disinterested demeanour slips.
Akin to Marbas, Naberius is based on a real thing. I guess the manga-ka liked the dog part most. Enjoy!
