Takumi Mayama (真山巧)

22 years old and a 4th year student at the start of the series, Mayama is from Kanazawa, Ishikawa-ken and an architecture student at the art institute. He lives in the same complex as Takemoto and Morita. He occupies room 101, sharing the floor with an unknown individual and formerly Lohmeyer-senpai. He acts as a senior to Takemoto and tries to help Morita get up for early morning classes.


Mayama eventually landed a job at Fujiwara Design. He has to deal with coworkers that are also very interested in his love life, and make comments whenever they can. Mayama also has to keep watch of his boss, Nomiya, whom he considers to be a playboy, when Nomiya begins to take an interest in Yamada.

Mayama doesn't return the feelings that Yamada has for him, but he sees Yamada as his close friend. Yamada's innocence is one thing that Mayama has to constantly guard from Nomiya, who has developed an interest with her.

When Fujiwara Design later broke up, people had to either stay in the Tokyo branch or transfer to the Tottori branch. Nomiya arranged for Mayama to be transfer to the Tottori branch, but as soon as this was announced Mayama quit. He now works again with Rika at her company, Harada Design, after forcing himself into the position in his own way.
