Маяма Такумі

Takumi is a 4th year student at the start of the series and 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. At one point, Takemoto and Morita are seen sleeping alongside him in his futon. Morita also borrows Mayama's shirts from time to time because it's more comfortable. Mayama also hates being left out of the activities that the group holds, even going to the furthest extent to join them.

Mayama also used to help Rika out with various errands while Rika was disabled due to the accident that left her husband dead. It is during that time that Mayama develops feelings for Rika. It is unknown whether Rika fully reciprocates the feelings that Mayama has for her, but various flashbacks imply that Mayama and Rika have 'fooled around', or Mayama took advantage of Rika's disability to fulfill his desires, although this is cleared up later as not being the case. Rika suggested that Mayama find another job so that she wouldn't have to continue hurting him, as she realizes how much he cares for her, and is unable (and perhaps unwilling at that point) to allow him to enter into her life.
