Seikenshi Densetsu: Samurai Spirits

Six warriors—Haohmaru, Nakoruru, Wan-fu, Galford, Tam Tam, and Charlotte—are destined to maintain the seal binding the dark god Ambrosia. After being defeated by Amakusa, their souls were reborn a hundred years later. As Ambrosia's return becomes imminent, five of them reunite to fulfill their duty. Haohmaru, however, chooses to focus on refining his sword techniques rather than rejoining the others.
