Rin Eba

Rin is the adopted younger sister of Yuki Eba, known for her devilish charm and sharp-tongued nature. Initially driven by an intense attachment to her brother Yuki, she viewed protagonist Seidai Kirishima as a rival and delighted in manipulating him through lies and seduction. As the story unfolds, she blossoms from a short-haired girl into a striking university student, gradually developing genuine feelings for Seidai along the way. Though she occupies a supporting role, Rin serves as a vital thread connecting the cast and propelling the story's emotional core.
