Asagi is a university student and a friend of Tokiwa, one of the male protagonists. It is established that he has previously attended a mixer with Tokiwa, indicating they are part of the same social circle.

Asagi possesses a personality that is both honest and sociable, making him approachable and easy to get along with. However, these traits are coupled with a notable degree of naivety. His demeanor is such that female otaku characters within the story find him reminiscent of a dog, suggesting a loyal and earnest, if somewhat simple, nature. Other characters, including his friend Hagi and Tokiwa, have expressed the opinion that Asagi is the type of person who will be easily taken advantage of or swindled as he gets older, further highlighting his innocent and trusting disposition. One review of the series describes him as the innocent character with the personality of a golden retriever.

In terms of his role in the story, Asagi is part of the group of male college students who find themselves attending mixers with a group of women who cross-dress as men. His personal narrative develops alongside these events. Notably, Asagi appears to make the most progress in his romantic pursuits. He spends an entire day with a character named Fuji at a comic convention, an event to which she had invited him under the guise of a festival. Their time together extends to dinner, and he ultimately stays overnight at her apartment. While other characters suspect something intimate occurred, Asagi's profound innocence makes such an outcome unlikely. This suggests his role is that of a genuinely kind and unaware young man whose relationships develop more out of earnest connection than calculated intent.

Asagi has no notable abilities or special skills mentioned in the context of this series, as the story focuses on everyday social and romantic interactions among college students.
