Kip. 24: The Boy Who Returned
Tokiya Inoue, Chisato's older brother, unexpectedly returns from his mission trip studying on birds. As Chisato introduces him to her friends, Miyu realizes that he is a stray shinma. After school the next day, Hisae overhears Tokiya challenging Miyu to the duel at night, and she goes to inform Yukari about it. It is revealed that Tokiya possesses a bird crest on his back given by a mysterious talking bird he had encountered during his trip. Yukari and Hisae witness Miyu and Tokiya passing through a demon gate. There, Tokiya transforms into a shinma known as Hiyoku. After a while, Miyu is able to return Hiyoku into the darkness, but Tokiya dies from the fire. Yukari and Hisae are then startled upon seeing Miyu coming out from the demon gate. (Source: Wikipedia)
