A classmate is a princess knight!

When a tragic accident cuts short a school field trip, Odamori finds himself offered a second chance at life in a fantasy realm. Reborn with the dark gift of a "Slavemancer"—the ability to bend others' wills to his command—he must navigate a world where his newfound powers make him both feared and hunted. As he grapples with the moral implications of his abilities, Odamori's path crosses with formidable adversaries who seek to stop him, setting the stage for a complex tale of power, identity, and the consequences of wielding absolute control over others.
