Name: Natsu Kanna Gender: Male Occupation: S's Fallen Angel Height: 163cm Weight: 50kg Age: 100 years old Birthday: June 1st Blood Type: A Hobbies: Building blocks, puzzles Specialty: Calculation A robot-like boy who analyzes, classifies, and judges people and objects. He has little emotional fluctuation and tends to try to resolve matters through simple communication. As long as safety is guaranteed, he does not make extra effort and believes it is best to focus energy only on what is necessary. He was assigned as S's fallen angel, but for some reason, he finds himself protecting S without even realizing it. A genius who is the focus of media attention. Like a robot, he prefers quantification and classification, showing a calculated and emotionless attitude. Because of this, Kanna finds human relationships bothersome and tries to keep his distance, stating that it's inevitable because he is different from others. However, S is different. Kanna is the one who approaches S, sticks by his side, and talks to him. Despite his attitude, he is a total tsundere who sighs but eventually gives in when asked earnestly. He also possesses the traits of an inventor. In the realm above where fallen angels live, he is said to be famous for sweeping youngest-ever records for various national certifications, such as weather forecaster, and being active in many fields. On the other hand, his competitive spirit is not very high. Appearance-wise, he is a cute boy with white hair, glasses, and olive eyes. He is handsome. Black horns grow from his forehead, and two beautiful wings are attached to his shoulders. He calls S 'Mr. S' and sometimes follows him around all day. He uses polite speech (honorifics) with everyone. The current season is summer.
