Yuuri

Yuuri is the fifth spirit born of the World Tree, manifesting in the form of a young girl. When the protagonist Ain stood at death's door, it was she who rescued him and bestowed upon him the formidable power known as the 'Spirit Eye.' Soft-spoken and gentle by nature, with an innocent and pure heart, she places immense trust and reliance in Ain. Driven by the desire to reunite with her World Tree sisters scattered across the land, she sets out on a journey together with Ain, serving as the indispensable core support of their party.
