Dreaming of being an idol since she was young, Haruka is a very cheerful and hard-working girl who loves to sing.

Because spending time together is an important value to Haruka, she loves her friends and fellow idols from 765 Production immensely and is happiest when she can work and sing together with them. However, she is shown to be very clumsy, often tripping and falling over nothing. Despite this, she enjoys engaging in physical activities, such as dancing or sporting events. 

Haruka's voice should be energetic and fun.
