3×3 EYES

A young man named Yakumo Fuuji becomes an immortal servant after his life is saved by Pai, the last of a race of immortals with three eyes. In the process, Pai absorbs his soul, granting him immortality. He embarks on a journey with Pai, seeking a way to regain his humanity. The journey is complicated by Pai's dual personality—one gentle and charming, the other serious and powerful—and the development of romantic relationships.
