Riho Kaguya

Riho is an honest woman with sharp perception, able to move hearts with the "soul" born from her talent and her devoted stance towards hard work. Her clear, husky voice has the power to punch its way into the listener's soul.
A vocalist worthy of being called a diva, her voice is the crystallization of natural talent and hard work.

However, her stance of refusing any and all compromise combined with her devastating lack of communication skills often results in conflicts with others who spend their lives waiting for things to come along, and causes them to think of her as self-righteous and egotistical, leaving some people to view her with hostility, but since she's completely indifferent to everything that doesn't attract her interest, it hardly ever hinders her daily life.

Her dream is for her songs be heard around the world. Achieving it lies at the end of an extraordinarily long journey, but her conviction never wavers.
Until the day she reaches her dream, she will never give up.... But she has zero talent for writing lyrics.
