Yuti

Yuti hails from another world, where she trained under the tutelage of the 'Bow Saint'—until her master was betrayed and killed by humans. Consumed by the corrupting 'Evil' power, she was driven to seek vengeance against humanity. It was the protagonist, Tenjo Yuya, who purified her from that dark influence, after which she accompanied him to the real world and began attending Ousei Academy. Though her quiet nature and lack of modern common sense set her apart, the care and guidance she received from Yuya gradually drew out her genuine, innocent side, nurturing a deep sense of trust and affection toward him.
