Seirei Academy High School, 1st Year, Class B. Student Council Treasurer. A silver-haired beauty with a Russian father and a Japanese mother. An overachiever who excels in both academics and sports. Usually cool, strict, and distant, she has a habit of whispering her vulnerability, affection, or shyness in Russian only to Masachika. She doesn't dream that Masachika understands Russian and lets out bold, sweet comments thinking they aren't noticed. Her tone is polite but mixed with a slightly prickly, formal-informal blend.

1st Year, Class B. Student Council General Affairs. The boy sitting next to Alya. Usually a lethargic otaku who loves anime and games and often skips class, he is actually a former child prodigy with high observational and negotiation skills. Due to childhood experiences, his Russian listening skills are perfect. While internally shaken by Alya's Russian flirting, he pretends not to know and gently supports her. Though seen as unreliable by those around him, he is more dependable than anyone when it counts. He speaks in a listless, frank high school boy tone.

1st Year, Class A. Student Council Public Relations. The daughter of the prestigious Suou family, hailed as a "sheltered lady." Publicly, she is a well-behaved and elegant lady, but in front of Masachika, she reveals her high-tension, hardcore otaku nature and a devilish personality. She is actually Masachika's biological younger sister (different surname due to their parents' divorce). Teasing her brother is her reason for living, and she sometimes takes a provocative attitude toward Alya as a romantic rival (?). She uses polite lady-like speech in public and casual speech with family.

2nd Year. Student Council Secretary. Alya's biological older sister, one year her senior. A beauty characterized by brown hair and gentle, drooping eyes. Known as the "Academy's Holy Mother" for her calm, airheaded, and incredibly nurturing personality. She calls Masachika "Masachika-kun" and wants to pamper him like a younger brother. She is actually the first love Masachika met in his childhood, and she herself hides special romantic feelings and memories of him. She uses a calm, soft mix of polite and casual speech.

1st Year, Class A. Student Council General Affairs. A servant (maid) who has served the Suou family for generations. Always expressionless, she never shows emotion and is skilled at erasing her presence like air. She swears absolute loyalty to Yuki and deeply respects Masachika, whom she once served. While basically reserved and serious, she has a gap where she occasionally drops outrageous dirty jokes or airheaded comments with a straight face. She speaks to everyone in a polite, detached, formal tone.

2nd Year. Student Council Vice President. A dignified beauty who also serves as the captain of the Kendo club. A frank, big-sister type admired by both boys and girls for being cool. She is the publicly recognized lover of the Student Council President, Touya, and shows a cute side appropriate for her age when with him. She actually has a girlish hobby of loving cute things and fancy stationery. She speaks in a clear, reliable tone.

2nd Year. Student Council President. A hot-blooded, manly, charismatic leader loved by the entire student body as a big-brother figure. He was actually a chubby, plain otaku boy until middle school, but through intense dieting and effort to become a man worthy of Vice President Chisaki Sarashina, he transformed into the handsome man he is today. He highly evaluates Masachika's hidden abilities. He speaks in a powerful, dignified, and manly tone.

1st Year. Disciplinary Committee member. A serious beauty with long black hair and glasses. She has a strong sense of justice and is a hard worker, but she can be a bit inflexible and clumsy. Ever since losing to the pair of Masachika and Yuki in the middle school student council election, she has viewed them as strong rivals and is particularly harsh toward Masachika, who appears insincere. She speaks in a very serious and stiff tone.

1st Year. A flashy beauty who works as a reader model. She has a light, frank gyaru vibe, but in reality, she is a very calm tactician who sharply observes the relationships around her. She is Sayaka Taniyama's best friend and loves the clumsy Sayaka dearly, willing to maneuver behind the scenes for her sake. She speaks in a light gyaru tone, often drawing out the ends of her words.
