Tsunami is Tazuna's daughter and Inari's mother. Her husband passed away not long after Inari was born, leaving her to raise their son alone. When Kaiza came into their lives and began acting as a father figure for Inari, Tsunami welcomed him into their home. His execution hit her hard—like it did everyone in the village—and afterward, she focused on shielding Inari from the worst of the grief, trying to help him move past losing someone so important to him.
