Maria Takayama

Serving as the supervisor for the Neighbor's Club, this young nun is a brilliant child prodigy whose academic success often masks her immature and rude tendencies. Though she frequently calls others "rotten mandarin," she shares a sweet, sibling-like bond with Kodaka, even joking about a future marriage. Despite her advanced intellect, her social skills suffer from skipping grades, leaving her gullible and prone to jealousy. While she acts cocky about her grades, she secretly longs for true friendship.
