Omi Kiriyama

A second-year student at Kouta’s school, this silent and brooding individual is secretly a wind-controlling sickle weasel. Once a bitter rival to the Minamoto siblings, he eventually rises to power as the leader of the school’s delinquent gang. Driven by a deep resentment toward the bond shared by Kouta and his companions, his path crosses violently with Kouta’s during a moment when the latter attempts to protect Chizuru from harm.
