Kouki Kamishiro

Kouki Kamishiro is the childhood friend of heroine Sakue Iwata, having grown up alongside her from a young age. As a child, he was frail and small in stature, often relying on Sakue for protection. However, once he entered middle school, he underwent a dramatic transformation, growing to over 180 centimeters tall and becoming a refreshingly handsome young man. Now a member of his high school's soccer club, his earnest, hardworking nature and bright smile—complete with distinctive fangs—have earned him considerable popularity on campus. Although he and Sakue remain close, he seems largely unaware of the long-held feelings she has quietly harbored for him.
