Rui is an outgoing and fun-loving girl, who will do just about anything to catch someone’s attention. She doesn’t necessarily care for what is right and wrong; rather, only cares for what pleases another party. She is outspoken, often flirtatious and perverted, and seems to be advertising her business at any point in time.

Her voice is meant to be more high-pitched, she makes a lot of cutesy noises to appeal to her audience.
