Maria Mikhailovna Kujou—known affectionately as Masha—is a second-year student at Seirei Private Academy, serving as the Secretary of the Student Council. She is the older sister of Alisa "Alya" Mikhailovna Kujou. Known as the school's "Madonna" (Gakuen no Seibo), Masha is idolized for her gentle nature, stunning physical beauty, and warm, deeply comforting maternal presence.

Unlike her sharp and competitive younger sister Alya, Masha is airheaded, laid-back, and endlessly gentle. She is prone to doing odd or eccentric things with a serene smile on her face, such as talking to pictures in her locket or buying plushies for the student council room. Beneath her doting, sweet demeanor, however, Masha is surprisingly perceptive and emotionally intelligent. She acts as a stabilizing force for everyone around her, frequently offering comforting hugs, sweet words, and subtle wisdom when people are feeling overwhelmed.
