No matter what I'll always protect you
Masami is a girl with long, messy brown hair and deep grey-blue eyes. She has fake reading glasses on top of her head.
She is often seen with a wide, white scarf resting on top of her matching navy collared shirt and jacket that represents her group, "Hiyoshi Town Propellers". This is followed by having lighter tones of clothing such as a complimenting baby blue jeans and high white boots.
Masami is a kind girl who cares about her subordinates and those close to her. She is rather stubborn with her secret identity Macha Green being revealed. It's quite funny since everyone knows she is Macha Green but she still insists that she is not and hides away to change into her Macha Green costume. .
Nozomi and her are neighbours. They are so close that they are practically sisters. They grew up together and Utoku cares for her like a big sister. When they were children, she pretended to drown and so Moritomo Nozomi tried to rescue her. However, things didn't turn out well and Nozomi was the one ended up drowning! They were both rescued. Because of this past incident, Utoku didn't want to be protected by Nozomi anymore and wanted to protect her and not make her worry anymore. They both care about each other a lot.
She is the leader (Best) of the group "Hiyoshi Town Propellers". A Best who fights for Tokorozawa as the green-suited superhero "Maccha Green (マッチャグリーン Matcha Gurīn?)," though everyone but Nozomi has correctly guessed that they are the same person. Heavily injured after fighting with Kuniko.
