She is voiced by Stephanie Sheh.
She is a strict and loving mom and wife who clearly wants the best for her children, but her tendency to disapprove of everything she finds unproductive has led to Miko becoming very disconnected from the family, which in turn has led to her forcing Miko to spend time with her siblings whether they like it or not.
She is her middle daughter and Mayumi loves her just like all her kids. Miko dislikes how her mom is strict with her with doing something more "proactive" and doesn't show support for her love for video games. Despite this, they both love each other, becoming closer after Miko is given her job at Hinobi.
She knows that he is a good friend of her daughter Miko and trusts him to keep her from harm's way.
She is her youngest daughter and Mayumi loves her just like all her kids. She tried to cheer up Lexi by taking her to get some frosty freezes in Karate Trainer.
She is her older daughter and Mayumi loves her just like all her kids. Mayumi is very demanding toward her kids to get along and spent time together especially, towards Nica and Miko.
Miyumi is an older-looking Japanese woman. Her hair is straight and parted to one side. She is often seen wearing white, high-waisted pants that end beneath her knee, and a pink short-sleeved sweater.
