Uktena Ahroun Homid
A tall Japanese teenager, with horns that sprouted from his temples and curved to the front of his head. (Think DnD Black Dragon) He always wears the traditional Japanese attire and has a katana on his waist.
Oni Marked was the only surviving member of the Tokyo Section 7 office. The only reason he was not killed when it was destroyed was because he was out hunting BSD’s. He was then given a transfer to the Iowa office, and arrived just in time to see the building burning down. He remained in the state of limbo, until recruited into the A Team.
