Kazama

Yamada's senior is a man with a flashy appearance and a lighthearted attitude, who is newly married. In Episode 1, he invites the uptight Yamada to the unfamiliar bar "Snack Basue," but after a misunderstanding there, he runs away. After that, he occasionally appears in Yamada's stories, and reappears in Episode 48. This time, he has become a regular at "Snack Basue" and begins to interact with Yamada more, often in a bothersome manner. As a regular customer, Akemi also refers to him as a troublesome person.

He is also a former classmate of Morita from their middle school days. They had not met once since graduation, but they coincidentally reunite at "Snack Basue." Because their personalities are complete opposites, Morita finds him difficult to deal with, and his name is occasionally mentioned in Morita's own episodes.
