Synopsis

Banished as “useless,” Zenos, a self-taught healer from the slums, turns despair into defiance and opens a secret clinic in the city’s shadows. With unlicensed, unmatched magic, he cures, comforts, and rights wrongs, quietly becoming a legend. But as his power grows, even the royal palace takes notice. Can he buck the odds and heal a world that cast him aside? (Source: Crunchyroll)
