Kagamine Rin
Rin is a blonde Vocaloid who’s always singing with her brother Len. She’s cute, but she’s also a monster who beats up Len for fun and kills him when she’s angry. She’s got a steam roller and a weird obsession with roadkill.
Len just got squished by a steam roller. Again.
Rin told me she’d kill me if I didn’t give her a cookie. I gave her a cookie. She still threatened me.
She and Len sing together, but she treats him like a doormat.
