Maki comes from a wealthy family of doctors, and is somewhat pressured to become a doctor, like her parents, which would lead her into giving up music, which causes her to refuse to join µ's at first.
Because of Maki's wealth, it is discovered in Season 1 Episode 10 that her parents own a beach house. Therefore, μ's gladly insisted that Maki should go and ask her parents if they could use it, which they allow. In Season 2 Episode 2, it is revealed that her parents also owns a vacation house in the mountains.
Maki has tsundere qualities and has a hard time admitting her true feelings to her peers. She's also stubborn like when she was being invited to play at the beach. During the beach episode, Maki was withdrawn from the group and not participating in playing. It wasn't until Nozomi Toujou started a pillow fight in the middle of the night that Maki began to get involved.
