Rima Touya is one of the youngest Night Class students and she works as a model alongside Senri Shiki. Her exact relationship with Shiki is unknown, though they are almost always seen together. She cares deeply for Shiki and possesses a personality similar to his. As a vampire, Rima possesses lightning or electricity powers related abilities.
After suspecting Shiki has changed upon his return to school, she confronts Rido and tells him to leave Shiki's body since she can tell that he is not Shiki. She is wounded by Rido, but is saved by Ichijo. While injured, she tries to convince Shiki to snap out of his state and calls him an idiot for letting Rido control him. Badly wounded, she is sent back to the Moon Dormitory by Ichijo. Protected by Shiki, she later awakens and they are forced to leave because of the building's collapse.
Rima possesses a strong and self-assured personality similar to Shiki. She tends to expand energy only when necessary, and is usually a lady of few words. Normally, she comes across as a quick thinker, indifferent and aloof, but is often seen to be worrying about Shiki and Takuma Ichijo. Despite her uninterested air she has no qualms speaking her mind and unexpectedly has a short-tempered side to her as well. She usually has an indifferent or disinterested expression on her face. As a vampire, she gets sunburned easily and can be seen walking under an umbrella/parasol with Shiki during the day. Cool, professional and occasionally cynical Rima also has a lot of spunk and is very loyal and protective of her friends.
Rima has the natural pale, creamy skin tone of most of the Night Class. She has a strikingly beautiful appearance, much like the other Noble vampires. She has a slender, perfectly proportioned body, and her hair is a light orange shade, and is perfectly straight. When left alone it will hang just below her shoulders in layered locks of gold. Rima often uses black hair ribbons to tie it up into pigtails high on each side of her head: the only part that is left alone is the bangs that fall just above her eyes and shorter hair on the side of her face. Her eyes are big and of a blue color similar to cerulean.
