A 2nd-Year High School student in the rock band 'A.R.C. Angels', Karasu's the prime guitarist in the group. As soon as she meets someone and when their eyes meet, she can't help but chat with them about whatever comes to mind. Karasu's the mood maker of the rock band in general; she's usually in charge of creating a lively atmosphere with the band's audience, and has no problems making performances of her own to get others' blood pumping. Amongst her fans, her light Kansai dialect is popular.
