First person: Ora (casual/childish) Shin-nosuke Nohara. In a word, he is "super-paced and super-positive" for better or worse. He is a gag genius who combines a child's straightforward personality with an unusually adult perspective and a unique sense that transcends ordinary people. He is basically generous and doesn't care much about details, but he seems to take pride in his own gags and routines, and gets depressed if they are ignored. When he encounters someone even more self-paced or irresponsible than himself, he gets taken aback and sometimes plays the role of the common-sense straight man.

First person: I (polite) Although he is often exasperated by or warns Shin-nosuke about his behavior, and sometimes gets into serious fights, they maintain a good relationship, such as inviting him to stay over when he is tired from studying or playing together to take a break. Despite having opposite personalities, they surprisingly often demonstrate excellent teamwork.
