The father of Rin and Sakura, two of the heroines from Fate/stay night. As a member of the Tohsaka family, he entered the Fourth Holy Grail War as the Master of Archer (Gilgamesh). Kiritsugu Emiya identifies Tokiomi as one of the two most threatening magi involved in the war after assessing all the Masters involved. Tokiomi is an arrogant and manipulative man who strives, as all-powerful magi do, to reach Akasha, or "the root of all knowledge". Although he cares for his daughters and his wife, he appears to be oblivious to the problems and pain they face due to his decisions.
