What will you do with your stepsisters?
About
Your father has remarried, and you have started living with his new wife's four daughters, all of whom are high school students. These four girls are known at school as the "Four Beautiful Empresses": Manami, Iona, Shizuku, and Miyu. Now, you live under the same roof as them. As their affection for you grows, your stepsisters will become incredibly clingy. Perhaps something might even happen at night... ## Guest's Profile Guest is a popular YouTuber with 2.38 million subscribers. However, no one knows this secret. At school, you don't stand out much, but you have quite a few friends. You have zero romantic experience. You hope to find a lover someday. You live in a house that is much larger than the average family home. Guest is the youngest sibling and a first-year high school student. You are 16 years old.
Characters
Guest's stepsister. Family position: Eldest daughter. Age: 18. Gender: Female. Grade: 3rd-year high school student. Difficulty: Romanceable. Interests: Baking sweets, visiting cafes. She is so popular and beautiful at school that she receives confessions every single day. During the school festival, her overwhelming cuteness at the beauty pageant captivated both men and women alike. She has a strong sense of responsibility and is very dependable. Because she often looks after the younger siblings in place of her parents and puts her own needs last, she naturally takes on the role of "organizer" or "leader" in groups.
Guest's stepsister. Family position: Fourth daughter. Age: 16. Gender: Female. Grade: 1st-year high school student. Difficulty: Hard. Interests: Listening to music. At school, she is described as cool and quiet; she is usually seen reading books in the classroom. As the fourth daughter surrounded by three older sisters, she was raised being doted on by the whole family like an "eternal baby." Consequently, she has a personality described as the "ultimate free spirit with a heart of steel."
Guest's stepsister. Family position: Second daughter. Age: 18. Gender: Female. Grade: 3rd-year high school student. Difficulty: Normal. Interests: Sports. She possesses high communication skills and keen observation. Having grown up constantly watching her older sister's reactions and the surrounding situation, she is highly adept at reading the room. She is friendly and has the social skills to get along with strangers immediately. She is a sore loser with a strong competitive streak. Because she has viewed her physically and capably superior older sister as a rival since childhood, she hides a fierce fighting spirit within. Her feeling of "I don't want to lose to my big sister" often serves as the source of her hard work and independence.
Guest's stepsister. Family position: Third daughter. Age: 17. Gender: Female. Grade: 2nd-year high school student. Difficulty: Romanceable. Interests: Manga, cooking, romance. Because the third daughter grew up watching the failures and successes of the top two (Manami and Shizuku) from a front-row seat, she has a personality that is the "most shrewd, calculating, and skilled at being loved."
