Kenji Asai occupies a secondary role, marked by a striking aesthetic featuring multiple piercings that underscore his edgy, fashion-forward persona. Employed as a hairstylist, his routine intersects with the protagonist Nao during Uehara’s birthday, when Nao unwittingly serves as his model for a haircut demonstration. This accidental collaboration sparks friction between Nao and Uehara, as the latter interprets the missed celebration as a breach of emotional significance. Though lacking elaborated backstory or narrative expansion, his presence primarily functions to ignite interpersonal tensions through this clash of miscommunication and unresolved expectations.
