Dreaming of changing the world for good, Akuto Sai transfers to Constant Magic Academy where he befriends a virtuous ninja clan member, Junko Hattori. On the way to the academy, they vow to make the world a better place together; however, the situation suddenly takes a turn for the worse upon his arrival—it is prophesied that he will become the Demon King!

A hopeful teen’s destiny to become the Demon King turns school life into a chaotic battle of fate versus will.
Akuto Sai arrives at Constant Magic Academy with a simple goal: to use his newfound magical abilities to better the world. He quickly bonds with Junko Hattori, a disciplined ninja‑student who shares his idealism, and the two pledge to reshape society together. Their optimism shatters when the school’s oracle announces that Akuto is destined to become the Demon King, a title that instantly casts a shadow over his reputation. Whispers spread through the campus, turning classmates and teachers alike into wary onlookers, and even Junko’s confidence wavers as the prophecy takes hold. Refusing to accept a fate written in prophecy, Akuto fights to prove that destiny is malleable. Yet every attempt to defy the label only seems to tighten its grip, as his burgeoning powers attract a motley harem of girls—each with her own agenda, from righteous vengeance to unabashed adoration. Between battling skeptical peers, navigating increasingly absurd situations, and confronting the growing darkness within himself, Akuto must decide whether to succumb to the ominous title or forge his own path. The series blends over‑the‑top action, slap‑stick comedy, and risqué fanservice while probing the age‑old question: can a person truly rewrite the script written for them?
