Ryouhei Kuze

At the beginning of the series he treated Akira as an enemy but Akira still sees him as a friend. His treatment to Akira is due to the fact he didn039t accept Yuki039s feelings and that Akira is Mina039s servant in which Ryohei believes he is siding with the vampires. His hatred towards Vampires is so strong that he agreed with students beating up Hikosaka because he quotassociatedquot with Mina. However after chatting with Angel he decided to apologize to Akira which Akira accepts. Source: Wikipedia
