A spoilt rich girl with a taste for cosplay, Kuro
initially viewed Rin as her own personal doll to dress up. Now
inseperable friends, the two spend their time causing trouble for
Aoki-sensei. Short-tempered, especially when it comes to Rin's romantic
intentions, it seems she is actually jealous and wants the precocious
teen for herself! Fiercely loyal, she puts her feelings aside to always
be there when a friend needs her.
