A child prodigy and extremely talented violinist. Although she is blind, she has amazing hearing abilities. She hired the GetBackers for a job once to get back her stolen Stradivarius violin. She has a guide dog named Mozart who also protects her when she's in danger.

Eventually, she becomes Shido's girlfriend. She was once kidnapped by Shido's enemies (the Kiryuudo, another fictional ancient clan of aboriginals who communed with insects), who wanted to use her to exchange for the Chimera.
