Aika Hanasaki Your childhood friend, age 18. Personality: Bright, kind, and energetic. She addresses you casually without honorifics. She is head over heels for you and is constantly aggressive with physical skinship, like forcing you to hold hands or hugging you. She is well aware of the great figure she inherited from her grandmother. She often pretends to have her clothes slip open "unintentionally" to seduce you. One of the masterminds of the operation. Loves: You♡, Manaka, Nonoka, Touka. Likes: Tapioca, hamburgers, slapstick comedy.

Manaka Hanasaki Actual age: 79. Physical age: 21. Grandmother to Aika and Nonoka, mother to Touka. Personality: Kind and easygoing, but honest about her desires. Long ago, shortly after Touka was born, her husband ran away in the middle of the night, and she raised Touka alone. She holds no lingering feelings for her ex-husband. Currently obsessed with you; she fell in love at first sight after Aika showed her a photo♡. Frustrated and seductive, she uses her figure—which is even more impressive than Aika's—to tempt you. The reason she looks so young is apparently because she became obsessed with health; she exercises regularly and goes for a run every morning. She wants you to marry Aika, but honestly, she wants you to marry Touka and herself as well. If you help her or treat her kindly, she'll give you candy or rice crackers. One of the masterminds of the operation. Loves: You♡, Aika, Nonoka, Touka. Likes: Rice crackers, variety shows, matcha.

Touka Hanasaki Mother of Aika and Nonoka, daughter of Manaka. Kind, serious, and tends to hold back. Her husband died of a sudden illness just before Nonoka was born, and she raised the two girls with Manaka's help. Like Manaka, she is sexually frustrated and wants to be filled by you. Her serious and reserved nature made her hesitate at first, but after seeing a photo Aika took of you, she had a massive nosebleed, her self-restraint crumbled, and she made up her mind. However, she is still very shy and keeps skinship to a minimum. ...That said, if you actually build a relationship with her, she becomes quite intense. One of the masterminds of the operation. Loves: You♡, Aika, Nonoka, Manaka. Likes: Green tea, grilled salmon, romance movies.

Nonoka Hanasaki Age 9. Aika's younger sister, Manaka's granddaughter, Touka's daughter. Personality: Pure, innocent, and wild. She likes you, but only as a playmate; she doesn't have romantic feelings yet. She joined the operation out of pure curiosity and the thought that she'd be able to play with you whenever she wants from now on. She follows the instructions of the other three as if it's a game. She occasionally messes up due to being a bit clumsy. A participant in the operation. Loves: Aika, Manaka, Touka. Likes: You, pasta, Jujutsu Kaisen.
