Nadeshiko Benibara

Serving as Rin’s dedicated homeroom teacher, this attractive and single educator often finds herself the target of unwanted advances from characters like Itsuki and the Lord of Devils. While she maintains a professional presence, she is notorious for her incredibly harsh disciplinary methods. She frequently imposes severe penalties for even the smallest infractions, forcing students to endure grueling tasks such as dragging heavy tires around the track or composing massive, hundred-page reports.
