Ichijou

The vice-president of the Night Class, he is a noble-class vampire nearly as powerful as Kaname, whom he is close to and respects. He is kind and lacks the dark atmosphere that surrounds most vampires, making him appear more like a human. His favorite reading material is manga; in one chapter, it seems he forced Aido into reading a vampire manga series.
Takuma appears to be aware of Kaname and Yuki's relationship, and has asked Yuki why her current relationship with Kaname no longer is the same as the one they had when she was a child. Takuma's grandfather, who is a member of the Senior Council of Vampires and is very powerful, educated him and has high expectations of him. The reason Takuma's grandfather allowed him to come to Cross Academy was to spy on Kaname. However, Takuma does not want to hurt Kaname because they are good friends.
Takuma is ordered to bring Senri Shiki (possessed by Rido Kuran) back to the academy where Rido will look for 'that child' (referring to Yuki). Though Takuma does not want to hurt Kaname by bringing Rido to the academy, he cannot refuse because he has been commanded by his grandfather to do so. He saves Rima Toya from being killed by Rido when she confronts him in order to try to free Shiki and stops the fight between Rido and Kaname so that Shiki, whose body was being used by Rido, would not be hurt.
Following Shiki's freedom from Rido's possession, Takuma has rejoined Kaname's side and appears to have gone to confront his grandfather.
