Character Arc
Kou Minamoto is a first-year student and a member of the Minamoto clan, a family line of exorcists devoted to subduing supernatural beings. Earnest, hot-blooded, and fiercely dedicated to his duty, he arrives at Kamome Academy intent on exorcising apparitions, including Hanako himself. His strong sense of justice and his black-and-white view of spirits initially put him at odds with Nene and Hanako.
As Kou spends more time around Hanako and Nene, his rigid outlook softens, and he comes to see that not all supernatural beings are simply evil. He forms a genuine friendship with the pair and becomes a loyal ally, lending his exorcism skills to their investigations even as he wrestles with the expectations placed on him by his powerful family.
Kou's arc explores his growth from an inexperienced, by-the-book exorcist into a more thoughtful and compassionate young man. His relationships with his stern older brother Teru and with the apparitions he once vowed to destroy challenge his beliefs, shaping him into a character defined by loyalty, courage, and a maturing understanding of the world he inhabits.
