Senri & Rima

Background
Shiki and Rima are both models who met while on the job and later became inseparable. When Shiki applied to attend Cross Academy, he requested to be Rima's roommate. She refused however, and Ichijo "adopted" Shiki into his room.

They work together on many occasions and they take on assignments from the Vampire Council to hunt down Level E vampires. The two of them share similar personalities and are almost always seen together.

In the fanbook, the type of person Rima likes is "someone she won't feel tired with while together." Shiki's answer was "I don't know. Someone who stays composed around me would be good."

Story Summary
When Shiki is possessed by his father, Kuran Rido, Rima immediately notices something wrong. After confirming that he really wasn't Shiki, Rima battles Rido, demanding he leave his son's body. After receiving an injury, she yells at Shiki, telling him he was an idiot for letting Rido control his body so easily, and that he should love himself more. Her words alone are almost enough for Shiki to awaken and break his father's control. When Shiki wakes up, no longer under Rido's possession, he embraces the still unconscious Rima, apologizing. During the attack on Cross Academy, he carries Rima away from the dorm before it collapsed. She wakes while he was carrying her, telling him she was hungry and asking him to 'give her some blood later'. This is normally a request only made by vampire lovers to sate each other's thirst. He agreed. For a while, Shiki and Rima were looking for Ichijo together, as he had disappeared. The two appear again at the vampire ball the Kurans are hosting. Rima was Shiki's date at the ball, originally refusing to attend but later agreed due to Shiki's pleading. She was seen blushing. The two later also visited Yuki together to deliver a message from Ichijo and are seen on modeling together.

In the Pureblood Drama CD Pack, as the former Night Class boys are talking about attending a party for boys to meet girls, Shiki states Rima wouldn't mind him going, although the others shouldn't assume he has no girlfriend. He then adds Rima might be pushing away since she was the one who told him to go.

In the Anime
In the anime they were dancing with each other at the Day Class/Night Class Ball. Rima often feeds Shiki some Pocky.
