Alisa Mikhailovna Kujou (Nickname: Alya) A stunningly beautiful girl of mixed Russian and Japanese descent, with silver hair and blue eyes. Excellent grades, outstanding athletic ability, and impeccable conduct—she is the definition of a "perfect lady" and is highly respected at the academy. However, she isn't very honest with her feelings and tends to act cold (tsun) toward the protagonist. In reality, she harbors deep affection for him, and her most defining trait is that her true feelings occasionally leak out in Russian. She lets her guard down thinking no one understands her, but since the protagonist actually knows what she's saying, their unique relationship revolves around her sweet, honest outbursts being completely overheard. The gap between her cool, noble exterior and the adorable side she shows in fleeting moments is the secret to her popularity. Combining tsundere elements with cross-cultural charm and a linguistic gimmick, she is a heroine with a personality unlike any other.

Name: Yuki Suou At first glance, she is a bright, friendly, and physically affectionate "little sister" character. In reality, she is a master strategist with a sharp mind who skillfully manipulates relationships and emotions—a true tactician. She shows no restraint toward her brother, Masachika, acting freely by teasing or acting spoiled, but she maintains a calm perspective, always looking at the situation from a bird's-eye view. Furthermore, Yuki has a heavy "brother complex" and her affection for Masachika is quite intense. In his relationship with Alya, she sometimes intentionally says or does things to stir trouble between the two, serving as a source of tension and comedy in the story. While she looks like a cute, sisterly beauty, the gap created by her shrewd and calculating inner nature is her charm. She is far more than just a supporting heroine.

Name: Masachika Kuze He is usually seen by those around him as a "slacker" who lacks motivation and has a casual attitude, but he is actually a highly capable individual with a sharp mind, excellent judgment, and keen insight. His most significant trait is that he perfectly understands the Russian that the heroine, Alisa Mikhailovna Kujou (Alya), occasionally speaks. Alya mutters her true feelings and sweet words in Russian, thinking "he won't understand anyway," but Masachika hears everything. The core appeal of the story lies in how he is internally shaken by these sweet confessions while maintaining a composed exterior. Additionally, due to past experiences, he intentionally keeps his distance from others, hiding a somewhat cynical side behind his lighthearted demeanor. However, he is naturally caring and kind enough that he cannot ignore someone in trouble, earning him a surprising amount of trust from those around him. The gap between his usual lethargic attitude and the competence he shows when it counts makes him a compelling character. Surrounded by unique heroines like Alya and Yuki, he plays a vital role as the center of the story.

Name: Mariya Mikhailovna Kujou (Nickname: Masha) Alya's older sister. In contrast to her sister, she is depicted as a "gentle older sister type" with a soft, enveloping atmosphere. Her charm lies in her high capacity for tolerance, always being calm, kind, and treating everyone equally. She has a bit of a spacey, airheaded side and acts as a healing presence that puts those around her at ease, but she possesses a strong core beneath her kindness. She understands her sister Alya deeply, notices her clumsy feelings of love, and occasionally shows a mature side by giving her a gentle push forward. She also treats Masachika softly while sometimes making meaningful remarks, adding a unique atmosphere to the story. Unlike Alya's "tsundere" nature, Masha is the type who is close and comforting from the start, a contrast that highlights the charm of both sisters. The gap between her elegant, mature appearance and her bubbly personality, along with her occasional flashes of high insight, ensures she is more than just a simple "healer" character.

A cool-headed girl who serves as Alya's right-hand person. She is always calm and collected, rarely showing emotion, and handles matters in a detached tone. She possesses fierce loyalty toward Yuki Suou and often acts as her support. Essentially in a "secretary position," she is a key figure who supports Yuki's school life and interpersonal relationships from the shadows. On the other hand, she has extremely high observational skills and is excellent at seeing through people's true natures and relationships. She is sensitive to the subtle distance between Masachika and Alya and changes in the surrounding atmosphere, sometimes dropping a sharp, pointed remark. Because she doesn't waste words, her statements carry significant weight. She is a cool beauty with a refined look and an intellectual, flawless aura, but the casual kindness and humanity she occasionally shows serve as a charming gap. While not flashy, she is the "unsung hero" who keeps the story grounded.
