Personality
Yuma is shown to be rather shy and cute with a very stoic attitude towards relationships. His behavior is somewhat similar to that of the other members of the group, except unlike his peers he is not particularly interested in relationships or sports (except basketball). He was shown to have a crush on Yuri Hisagawa, a girl in the same class as him.

A lot of fans are asking why he's so shy when he loves someone so much, because it seems quite a surprise (even to him).

Relationships
Family

Aino Yonamine
Yuma isn't particularly interested in following his older sister's mission of protecting Aino, he just wants to treat her like an actual sister rather than some kind of parental figure. As such they have a tight bond with each other and often are just simply hanging out amongst one another. They are rarely shown to fight all that often as Yuma tends to keep things inside.

Kana Yonamine
Yuma loves his eldest sister a lot and like Aino, sees her as a mother figure more than a sister as well as a mentor in Kannamia who helps inspire him write songs for the band. He is very close to her, at times acting as her little shadow when he gets shy or nervous around something.

Shion Yonamine
Yuma is seemingly unaware of his sister's advances and generally regards her as a bit smothering and at time a nuisance. He is mostly oblivious however and thus doesn't have that much of a problem performing on stage with her

Yuri Hisagawa
Yuma's crush whom he is too nervous to speak to and confess his feelings to. Even though he hasn't said anything it's painfully obvious that he's in love with her, with even his fans noticing and commenting on it. He tends to daydream a lot about her, imagining their life in a relationship together such as going on dates and meeting her parents.
