●A comic adaptation began serialization on the manga app 'Manga UP!' on January 17, 2020.

A world where battles are waged against grotesque creatures known as "monsters," which threaten humanity's very existence.

Keith, who earned the title of Sage at the youngest age in history, had achieved numerous victories during his year with the Eleventh Knights Order. However, after clashing with his incompetent superior, Benoit, he was dismissed and expelled from the order. Subsequently, Keith was summoned by his friend from his student days, Prince Alan. He was then instructed to serve as a teacher at the Royal Knights Academy in the capital, concealing his identity as a Sage—an assignment that was effectively a demotion.

However, as a teacher, Keith fully utilized his inherent skills and knowledge as a Sage, fostering the students in his class to an extraordinary level of strength.

Meanwhile, having lost Keith, the Eleventh Knights Order rapidly weakened, and Benoit was held accountable for the significant damage incurred in battles against the monsters.

This is a story of humanity, whose existence is continually encroached upon by monsters, gradually igniting the fires of a counteroffensive.
