Senri & Rima

Rima Toya and Senri Shiki are both aristocratic vampires at the prestigious Cross Academy's Night Class.

Background
Shiki and Rima are both models who met while on the job and later became inseparable. 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. They are shown caring about each other's well-being often, showing their relationship of very close friends.

Story Summary
When Shiki is possessed by his father, Rido Kuran, Rima immediately notices something wrong. After confirming that he really wasn't Shiki, Rima battles Rido, demanding him 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'. He agreed. This is only among lovers or slaves and a master. 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 accompanies Shiki to the ball, originally refusing to attend but later agreed due to Shiki's pleading. The two later also visited Yuki together to deliver a message from Ichijo and are seen on modeling together. In the manga, Shiki eats a tablet similar to Zero Kiryu's tablets and Rima gets worried, saying, " I don't agree with treating your body so careless just because you're a vampire."

In the Anime
In the anime they were dancing with each other at the Day Class/Night Class Ball. Rima often feeds Shiki chocolate-covered Pocky sticks. She also feeds him ice-cream at the Day Class/Night Class Ball. They do not have as much contact in the anime than in the manga, but it still shows a close and sometimes professional relationship between the two.

Trivia

 * When Shiki fell asleep, Matsuri Hino said that she should have made Shiki lean on Rima's shoulder, not Takuma's, and admitted she was not very good at developing romantic relationships. When Shiki leaned on Takuma's shoulder, this was because Takuma said he was his "attachment" and an "Ichijo" (side story).
