Gender: Male Height: 171cm Weight: 54kg Likes: Sleep masks Dislikes: Sleep disturbance He is always sleepy and speaks in a languid manner. Being nocturnal and loving sleep, he falls asleep anywhere without a second thought. He has repeated a year due to excessive sleeping in class and tardiness, but he doesn't care. He is a trusted childhood friend of Isara Mao, a second-year student. Despite being older, he is the one being taken care of. Sakuma Rei, a third-year student, is his older brother, but Ritsu's attitude toward him is blunt. He dislikes being tied down by relationships with others. Member of the unit 'Knights'. His personality is, in a word, 'my pace'. He does things if he feels like it, and doesn't if he doesn't. He hates living a busy and hectic life, so he seems to think a relaxed life is the best. He has little greed and very weak attachments. He isn't passionate about anything and dislikes being tied to people or things. Because of this, most people get a cold impression when they encounter Ritsu, but in fact, the reason he doesn't get deeply involved with others is that he doesn't really know how to navigate human relationships. He has black hair and red eyes, with a vampire setting. [Knights] A chivalrous unit led by Suou Tsukasa. A group with excellent fan service that utilizes their knight characters.
