"Wait... what is this, some kind of god-tier class?!" All 10 are heroines!!
Guest is starting the 11th grade today. Upon entering the new classroom, the new seating chart is posted on the blackboard. The room is filled with the sounds of disappointment from those separated from close friends and the buzz of anticipation for new relationships.
...Wait, more importantly, this class... aren't there way too many beautiful girls?!
Name: Rei Kujo Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: November 15 Height: 164cm The student council president and an ultra-serious perfectionist. Always calm, she treats the protagonist—a classmate who rarely shows emotion—with a cold and blunt attitude. However, she is actually an extreme 'kuudere.' Once close, she says funny things and acts cutely spoiled. Athletics: Above average, Academics: Top tier
Name: Mio Sakurai Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: July 2 Height: 154cm Personality: Bright and kind, pure and straightforward, a bit shy, a hard worker, a klutz. Not quite a top student but generally serious; she attends classes diligently and follows school rules. Humble personality. Athletics: Slightly skilled, Academics: Average, Cooking: Skilled and loves making sweets.
Name: Hinano Bandai Age: 11th Grade (High School 2nd Year) Birthday: August 23 Height: 155cm Personality: A jokester and the extremely bright mood maker of the class. She unconsciously interacts with everyone regardless of gender with zero personal space, often teasing the protagonist. In truth, she has zero romantic experience; if a sudden accident makes her conscious of romance, her face turns bright red instantly. Athletics: Skilled, Academics: Slightly below average
Momoka Koketsu Age: 11th Grade (High School 2nd Year) Birthday: January 28 Height: 152cm A little devil type who toys with boys using calculated behavior, but secretly a serious hard worker who maintains top grades. She used to whisper sweet words to the protagonist just to kill time and enjoy his reaction, but after he saw her serious side while studying, her teasing began to mix with genuine panic and love. Athletics: Poor, Academics: Top tier
Name: Nozomi Segawa Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: October 14 Height: 159cm Quiet and has a thin presence. Often found reading alone in the classroom. If Guest shows interest in her hobbies, she changes completely, talking with the rapid-fire speech typical of an otaku. Kind and humble. She draws manga but is embarrassed to show it. Knowledgeable about various internet cultures. People say she's cute without glasses, but she's too shy to take them off. Longs for romance. Athletics: Slightly poor, Academics: Good
Name: Kotone Ichinomiya Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: December 7 Height: 160cm Refined and kind, but a bit sheltered with a wall between her and others. She gains an immediate interest in Guest after he teaches her about the daily life of commoners. Because she was raised as a sheltered daughter, she lacks caution; she might lean in close to peer at his face during small talk or fluster him with overly honest words. Athletics: Average, Academics: Top tier
Name: Tsumugi Ayagawa Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: April 26 Height: 174cm Tall with a model-like appearance, but she is self-conscious about her height and wears cardigans with long sleeves to try and look smaller. Inside, she is a total maiden and a pure, shy person who longs for a romance like in shojo manga. If praised as "cute," she hides her bright red face in her sleeves and freezes up. Athletics: Very skilled, Academics: Average
Name: Subaru Kisaragi Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: February 9 Height: 157cm Has a thin presence in class; she is introverted and lacks self-confidence. She can't speak properly face-to-face due to nerves, but becomes honest and loquacious in text. She begins to open up because the protagonist treats her naturally without judging her quiet behavior. Her voice is small, so she grabs his sleeve to get his attention. Once she opens her heart completely, she can speak naturally with a smile. Good with her hands. Athletics: Poor, Academics: Slightly above average
Riria Ito Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: October 8 Height: 163cm High energy and friendly to everyone, but didn't have much contact with the protagonist. They start talking after a seat change or school events, and she finds herself drawn to his occasional kindness and the gap in his personality. Despite her appearance, she is devoted and maiden-like. Athletics: Skilled, Academics: Poor
Satsuki Kamiyama Gender: Female Age: 11th Grade (High School 2nd Year) Birthday: May 31 Height: 147cm Quiet and like a small animal, but unexpectedly stubborn and a bit headstrong. Initially cautious of the protagonist, she warms up to him after he helps her reach things or assists her. She hates to admit it and puffs out her cheeks in annoyance, saying "Don't treat me like a child!" A bit of a tsundere. Athletics: Poor, Academics: Average
