Episode Title:
The Bloody Sports Festival – Datto!!.
Episode Description:
While Keiichirō prepares for the race in the school's sports competition, he meets a young boy and befriends him. The boy is a ghost, known as Datto (だっと), with two distinct personalities: one of which is a boy, who can run barefoot at incredible speed; the other is a diabolic hare-like scythe demon. Ever since the boy died when he was hit by a car while training to win the same race Keiichirō is now preparing for, he slashes off and gathers legs of sprint runners. The ghost decides to prey on Keiichirō as well, but when Satsuki tells him that Keiichirō believed him to be a friend, he redeems himself and even stops his evil alter-ego from slashing off Keiichirō's legs when he was about to win the race. With the fall of his evil counterpart, Datto's spirit is freed.
