Takeshi is a long time friend of Savitar, Acheron Parthenopaeus, and others. He has a take-no-prisoners attitude. He just kills the ones around him. Savitar claims he's the one who invented war. He is lethal, quick, and older than dirt. Some claim he's one of the primal forces that forged the earth, and others claim he's demonspawn. The only thing anyone knows for sure is that his temper is quick and his justice is swift. Don't be fooled by his calm exterior; it just means he's sizing you up for a body bag. Along with Savitar, he trained Acheron after Artemis brought him back from the dead. Maybe one day we'll actually know something more about him. Takeshi makes his first appearance in the book Acheron.
