Yuuichi Yusa

The protagonist of the story. He appears as friendly and helpful, but detaches himself from others, cynically denying the existence of true love. His cold personality is a result of his upbringing, which took place in a brothel. Over many years, he came to associate love with material gain and sexual gratification, and thus does not hold any stock in it. Yuuichi lives alone in an apartment, attends a nearby college and earns money by teaching a junior cram-school.
