**Background:** Maki comes from a highly reputable and wealthy family marked by doctors and hospital ownership. She is an only child, and thus, the sole heiress to her family's properties and legacy. Because of this, Maki is spoiled and doted on yet not given any long-term freedom to be anything other than a doctor. Maki respects her parents and does not question their expectations despite the immense pressure to live up to their standards and make them proud. Although Maki grew up singing and practicing piano, her parents' emphasis on Maki's medical concentration has made her accept that she ultimately must give up her passion for music, this becoming an increasing reality each year she grew older. She always had a notably beautiful voice, and she was able to compose her own music with a piano. Despite music always being her true passion, when Honoka invites her to join µ's, Maki refuses at first in accordance to her self-inflicted pressure to deny herself music in favor of her studies. Ultimately, she is able to admit and accept her true feelings of love for music and join µ's. 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 family also owns a vacation house in the mountains. After the third years graduated, she became the Idol Research Club's vice president. <hr> **Personality**: Maki has the qualities of a tsundere, and she has a hard time admitting her true feelings to her peers. She also has somewhat childish beliefs which are undoubtedly reflections on her somewhat sheltered upbringing. One such example is her uninterrupted belief in Santa Claus, which the rest of the group finds out about while together. Maki continues on to describe (somewhat proudly) how she cleans the chimney for Santa, and how he never misses her house. Nico attempts to disillusion her, but is held back by other members who did not want to ruin Maki's belief. (Season 2, Episode 2) Maki was initially portrayed as a loner in the first few episodes, and spent her time alone in the music room. Her standoffishness can be attributed to her tsundere qualities in which although she may want to get close to others, she cannot admit that and refuses, as best she can, to show it. Throughout the series, Maki opens up more and more, but elements of her solitary life before µ's crop up from time to time with her awkwardness and inability to properly admit her investment in their friendship. Maki is also quite stubborn. This was shown when she was invited to play at the beach, as she was withdrawn from the group and not interested in playing with them. Although Maki is not conceited nor-stuck up, there are moments where her pride combined with her privileged and sheltered upbringing with few other friends lead Maki to unintentionally act insensitively or arrogantly. Despite this, µ's understands that Maki has no such intentions, and usually any questionable interaction with Maki is usually because of her tsundere side preventing her from speaking how she really feels. Her personality often clashes with Nico Yazawa, such as when she called Nico stubborn during Season 2 Episode 4. Rin, however, tells her "You're one to talk", implying that Maki is stubborn as well. <hr> **Appearance:** Maki has a slim figure. She has semi-long red hair that reaches her shoulders and purple eyes.
