Biwa

びわ

She adopted the name "Biwa" after the instrument of that name. Her father was a biwa player, and her mother was a shirabyoushi (female entertainer). The biwa she carries is a memento of her deceased father.
Biwa is an unusual character for an anime. She is not the protagonist who determines the flow of the story. She is the sky, watching the events unfold before her eyes.
She can see the future using her right eye, but she refuses to tell others what she has seen. Initially, she does this out of spite, holding a grudge over her father's death. However, in later episodes, she does so because she understands that the future cannot be changed.
