Sanda is a male swordsman affiliated with Ame, the former princess of the fallen nation of Ise. He serves as her retainer, fulfilling a protective role originally requested by Ame's deceased mother. His background includes prior military service, though the specific army remains unspecified. Physically, he is elderly, bears a scar, and has notable facial hair.

Sanda journeys alongside Ame's group as they seek the Holy Weapon Giga Road, a vital objective for countering the Shinobi—monstrous entities ravaging the world. His narrative culminates in a heroic sacrifice where he confronts a horde of Shinobi, holding them off to secure Ame's path to the Giga Road. This act results in his death.
