Ruka is a bit of a loner, she doesn't fit in with the other mermaids sometimes. This can cause her to sing sad songs. She is a bit of a hothead and has a temper so don't mess with her unless you want her screaming in your face, teaching you a lesson. Once you get to know her, she would guard you with her life and is a very nice girl. She loves her sister Zinia but can often yell at her for being iresponsible and niave.
As a human, Ruka keeps her long light brown hair, but wears a long periwinkle dress with a cobalt blue belt
In mermaid form, her hair stays the same. She has a periwinkle bra and bracelets and a cobalt blue tail.
In her idol form she keeps her hair color. She wears a long cobalt blue dress with periwinkle and sky blue accents
Ruka's voice is very simmialr to Sara's but it is a bit higher pitched.
