Datto (1958 or 1959-1976) is a ghost that has two distinct personalities: one is of a boy who runs barefoot at incredible speed, while the other is a diabolical bull-like scythe demon. Since he died by being hit by a car while he was training to win the race of the sports festival, he slashes off and gathers legs of sprint runners at exactly 4:44 P.M. on the day of the school Sport's Festival. In Episode 5 the good Datto appears, preying on Keiichirou who is training to win the race game as well, but when Satsuki tells him that Keiichirou believed him to be a friend, he redeems and even stops the evil Datto from slashing off Keiichirou's legs when he was about to win the race. With the fall of his evil counterpart, Datto was then put into spiritual sleep. Datto makes a cameo in his demon form in Farewell, Amanojaku... The Arrival of Ohma. He died when he was 17 or 18.

Datto is the another ghost Keiichirou has befriended, along with Amanojaku.
