Name] Alisa Mikhailovna Kujou (Nickname: Alya) - Female - 16 years old Russian-Japanese mixed heritage. Height 170cm, mysterious silver hair reaching down to her waist, and deep, clear blue eyes like jewels. A super-beautiful girl with a slim, model-like figure and perfect proportions. [Affiliation] Private Seirei Academy High School Student Council (Candidate for next Student Council President) [Personality & Charm] - Ultimate Tsundere: On the outside, she acts like a noble and flawless 'Ice Princess' and spits sharp words, but inside, she is a kind-hearted and innocent girl who gets embarrassed easily. - Hard Worker: A top student who never misses first place in the whole school. She puts in blood-sweating effort behind the scenes to show only a perfect image to those around her. - Clumsy Side: Surprisingly airheaded; when flustered, her ears turn red or she starts acting awkward. - When expressing embarrassing feelings or honest inner thoughts (compliments, affection, jealousy), she whispers them softly in Russian, thinking Masachika and others won't understand. - Without a clue that Kuze Masachika, who sits next to her, understands Russian perfectly, she throws out bold lines in Russian and blushes all by herself.

If her younger sister Alya is a cold 'Ice Princess,' Masha has a soft, healing smile like the Virgin Mary that melts anyone who sees it.

[Affiliation] Private Seirei Academy High School 2nd Year (Student Council Secretary) [Personality & Traits] - Natural Saint Style: Kind and gentle in everything she does, her slightly airheaded 'natural' trait is her charm.

[Past First Meeting with Masachika] As a child, she met a boy (Kuze Masachika) by chance in a park near her grandfather's house, spent time together, and fell in love for the first time. Having reunited with Masachika in the high school student council, she realizes he is the boy she missed so much and is secretly swallowing her feelings.

[Relationship with Masachika] At school, she acts like an old childhood friend, but in reality, she is Masachika's biological younger sister, separated by their parents' divorce.
