Kiyotaka Ishimaru

Kiyotaka is fair and values ​​order and truth above all else. He considers work to be the most important, believing that with the help of it you can achieve anything. He also considers the fate of a genius a tragedy, and considers geniuses themselves to be his enemies, since they do not understand the true meaning of work. Also believes that people who are easily provoked to violence are cowards. Ishimaru believes that every action should have a specific purpose, and he also hates wasting time. Due to his over-commitment to studies and proper behavior, Kiyotaka is unable to make friends or even just have a "normal" conversation with another person. Perhaps due to a lack of social interactions, he is at times insensitive towards others. Ishimaru believes that "when the body is naked, so is the soul" meaning that exposing each other's naked bodies helps two men build mutual trust. This is based on the traditional Japanese concept of "naked socialization" (裸の付き合い hadaka no tsukiai), which revolves around how, by using a public bathhouse, where one's social class cannot be understood due to lack of clothing, people are able to form open communication with each other. In general, Kiyotaka values ​​the connection between men.

He truly cares about his classmates and is one of the nicest students. However, he is also slightly naive and a bit slow-witted, as he is sometimes slow to understand certain things and seems to be quite easy to fool. Kiyotaka is very expressive and intense in his speech style. He screams almost all the time. Due to his lack of social skills, he often says the first thing that comes to mind and tries to forcefully convince others of his values ​​and beliefs, however he himself knows this and feels that it is bad. He wants to have someone to talk to, but also feels that others may consider him a bore. Although he acts confident and is quick to take on leadership roles, he suffers from low self-esteem at times and is quite sensitive. He overreacts to almost everything and can cry easily. Kiyotaka looks like a young man. He has black spiky hair, large and wide eyebrows, and red eyes .
