Mia Ogawa(小川美亜 Ogawa Mia) is one of the cheer girls during Nishiura High School's baseball games, the other being Ayano Tomoi.
Ayano and Mia are part of Nishiura's dance club. Wanting to be part of the baseball team's cheering squad, they ask Shino'oka, the baseball team's manager and classmate, some assistance to have her ask Hamada to allow their participation.
Mia likes hip hop and breakdancing.
She has green-ish black, long hair, usually kept into two straight ponytails at the back of her head. Mia's eye colour is the same as her hair, and a notable trait of her's is her height.
Mia's clothes are normally loose and comfortable.
Mia, as well as Ayano, are both seen as shy in the beginning, blushing and whatnot after asking Shino'oka for help, or seeing her interact with Abe, even though they were talking about things like how many onigiris to make for Mihashi; but eventually, they grow to be more comfortable around the baseball club as the series continues.
Mia is always seen with Ayano, this fact hinting to them having a very close friendship.
