Yase is a demon born from a picture—the daughter of Myoue and Koto. Growing up different from everyone around her left her struggling with depression, but her mother's warmth and reassurance gave her the emotional foundation she needed. That close bond with Koto stuck with her into adulthood; she's still deeply attached to her mother.
These days, Yase is one of three council members overseeing the City Through the Looking Glass alongside her brothers. She's become something of a socialite in modern Kyoto, known for throwing tea parties and hosting social gatherings. She's clearly made peace with being different—now she uses it to bring people together.
