Shaman King (2021)

A teen with a ghostly sidekick battles rival shamans to claim the throne that can rewrite the world.

In a world where the veil between the living and the dead is thin, shamans wield the power to commune with spirits, gods, and lingering souls. Every five centuries, these gifted individuals converge for the Shaman Fight, a high‑stakes tournament that crowns a Shaman King—an unrivaled conduit capable of summoning the Great Spirit to reshape reality itself. The story follows You Asakura, a laid‑back teen with a fierce ambition to become that king, and his loyal partner, Amidamaru, the restless spirit of a 600‑year‑old samurai. Together they navigate a modern Japan teeming with hidden specters, rival shamans, and ancient grudges. Their journey begins when Manta Oyamada, an average middle‑schooler, stumbles into a cemetery after school and encounters You, who is casually chatting with a gaggle of ghosts. Terrified yet intrigued, Manta discovers he can see spirits too—a rare gift that draws You into a fast‑friendship. When a gang of thugs threatens Manta, Amidamaru steps in, showcasing the raw, otherworldly combat that defines shamanic battles. United by their supernatural sight, the trio embarks on a globe‑spanning quest to collect powerful allies, master elemental techniques, and ultimately seize the throne of the Shaman Fight, all while confronting personal doubts and the ever‑looming specter of destiny.

A tournament battle series where teens partner with historical spirits to fight for the power to reshape the world. Expect supernatural action with emotional backstories involving death and trauma, but minimal sexual content and no graphic gore.
