Sayo

Sayo is a young girl living in a village within the Yakumo region of the Karaski Kingdom, and the sister of Shin. After Rio journeys to his parents' homeland and saves her village from peril, she develops deep and sincere feelings for him. Naturally shy and wholesome in character, she initially lacked any combat abilities whatsoever. Nevertheless, driven by an unwavering desire to stand by Rio's side and become a true source of support for him, she throws herself into mastering spirit arts with remarkable determination—proving that beneath her gentle exterior lies an iron will.
