Seirei Gensouki: Spirit Chronicles

A modern soul reborn as a street‑kid prince must master magic, school politics, and vengeance.

Haruto Amakawa, a disillusioned college senior, meets an untimely end on a rain‑slick highway, only to awaken in a foreign realm as Rio, a street‑wise orphan with a hidden lineage. The shock of swapping bodies is quickly eclipsed by the sudden surge of arcane abilities that accompany Rio’s new form. Haruto’s lingering thirst for vengeance against his mother’s killers fuses with Rio’s survival instincts, creating a volatile blend of modern cynicism and medieval grit. When a royal kidnapping draws Rio into a daring rescue, he saves the princess of Bertram and earns a place at the kingdom’s elite academy, a school reserved for the aristocracy’s prodigies. Inside the marble halls of the Royal Academy, Rio must navigate a world of polished nobles, fierce rivalries, and political intrigue while keeping his dual memories from tearing him apart. He befriends a motley crew of classmates—each harboring their own secrets—and gradually uncovers the truth behind his reincarnation and the mysterious forces that bind his past and present. As battles erupt and alliances shift, Rio learns that the path to power is paved with sacrifice, and that the line between revenge and redemption is thinner than a blade’s edge.

A college student reincarnates as a slum orphan in a fantasy world, gains magic, and enters a royal academy while building a harem of devoted girls. Expect standard isekai power fantasy with moderate fan service, fantasy violence, and themes of class prejudice and slavery that may need context for younger viewers.
