In an era where magic dominates every aspect of life, Jin, a young noble with a rare ability, has earned a fearsome reputation in the underworld as the Anti-Magic Noble thanks to his adversarial “spellbladeship.” One day, while on a mission, Jin encounters a mysterious enslaved girl named Lynette and takes her under his wing. Afterwards, Jin infiltrates a prestigious women’s academy with her, where he becomes the sole male instructor and starts teaching his unique fighting style to the young ladies. In a world of magical supremacy, this “anti-magic” shadowy hero is here to guide his misfit students to the very top! (Source: Manga UP!)
