Tamotsu Kodate is the father of Mamoru Kodate and head mechanic of ALVIS, first introduced in the Dead Aggressor portion of the anime.
As with all of Tatsumiya's adult citizens, Tamotsu was one of many affected by the sterilization of Japan's people by the Seto Inland Sea Mir. In the aftermath of this event and the resulting attacks on Japan, Tamotsu would go on to join Japan's Arcadian Project, making a new life on Tatsumiya with his wife, Chisato.
