Yuma Tonami 十波由真

Yuma is an athletic girl and is out-going. She pretends to be always in conflict with Takaki and that he's always trying to beat her in everything. She thinks he is her rival. Takaki never bothers to ask her why she acts this way until the last episode. She blushes and stutters, giving the audience the impression that she may have feelings for him. Her best friend is Manaka Komaki.
