Haruka is a optimistic and enthusiastic girl with a love for singing where her personality makes it easy for her to get along with most people she meets and she's commonly thought to just be a normal girl. Due to her nature, she can quite easily get along with almost anybody. However, she is shown to be very clumsy, often tripping and falling over nothing. Despite this, she loves to engage in physical activities, such as dancing or sporting events. 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.

This character speaks both English and Japanese and this role does require singing since she's an idol. Her voice is prone to give people heart attacks over how adorable and wholesome she sounds.
