Botan Arisaka is Mashiro's mom in Ao no Kanata no Four Rhythm. She's a supporting character, but fans often note how genuinely warm she is—the kind of parent who gets visibly excited when people cheer for her daughter. She actually rewards that enthusiasm with free udon, which is pretty endearing.
Appearance-wise, she's got purple eyes and light gray hair, always wearing a head cap. Under her white apron is a small green dress paired with black shorts.
Her personality is straightforward: she's happy most of the time, and her mood goes through the roof whenever someone shows support for Mashiro. It's one of those character details that makes her memorable despite being more of a side character.
