Mayumi Thyme

A classmate of Rin with striking heterochromia, this news-hungry girl possesses a unique half-demon heritage that manifests only through her mismatched eyes. Despite lacking traditional demonic traits like magic or pointed ears, she carries herself with immense confidence. Although Rin and Itsuki frequently tease her about having the smallest bust in the series, she remains unapologetic, viewing her petite stature as a rare and desirable trait for a specific niche of admirers.
