A 3rd year High School student in the rock band 'A.R.C.Angels'. She hates lies and equivocation. Because she carefully chooses her words she ends up not saying anything. Even in interviews, she is silent, so in the time she's considering what to say Karasu often acts as a proxy. Although she seldom speaks, there are fans who are crazy about her for that very reason. Her earnest style of playing the drums has caught the attention of many professional drummers.
She stuns opponents with her drum sticks clad with electricity.
