Probably only one person I know has read the "Dragon Knights" manga by Mineko Ohkami. So.......I gather pretty much nobody is going to know who this is! laughs

Tetheus...or Tecceous (according to the Romanized name listed on Mineko Ohkami's own homepage, which I visited once or twice a long time ago........) is a Youkai taken in by the Dragon Lord and serves in the court as the Head of Security. He's a skilled and talented fighter, but doesn't often get much in the way of scenes in the manga, until near the end of the series.

Tetheus/Tecceous belongs to Mineko Ohkami/Dragon Knights/Wings Comics. (Translated incredibly poorly by TokyoPop.......)
