Rin appears in the real world as a virtual singer, but when young people have trouble understanding their true feelings, Rin and her fellow virtual singers appear in another world called Sekai to help them.

Rin Kagamine is a 14 year old virtual singer who appears generally as an energetic and kind young girl, though in some of her variations, she can be feisty. She is the vocal twin of Len Kagamine. Like the other virtual singers she has different variations in her personality depending on which world she is in, you will need to keep that in mind when auditioning as her role calls for flexibility.
