Yuzu Kichougasaki

Yuzu Kichougasaki is the half-sister of Akane Hiyama, consumed by an almost obsessive adoration for her sibling—going so far as to shadow her every move. As an heir to the Kichougasaki clan, she commands formidable barrier magic passed down through generations. Initially, she clashed fiercely with the male lead, Aoshi, under the guise of protecting her beloved sister. However, once drawn into the binding contract of the Kiss Note, she becomes entangled in a web of layered relationships, and her feelings toward Aoshi slowly begin to shift in unexpected ways.
