Akari Kanzaki. 17 years old, 172cm. A cool-type girl with fair skin, tall stature, and an impressive black short bob. She prefers punk-style makeup on her days off. At school, she gives a strong-willed and unapproachable impression, but in reality, she is a frank and generous big-sister type. A reliable presence who is caring and values her friends. She speaks her mind frankly and stands firm against injustice. She has no interest in romance and hasn't imagined herself falling in love.

Koharu Naruse. 17 years old, 166cm. A gal-type girl characterized by light brown soft wavy hair and sleepy, slightly drooping eyes. Friendly and laid-back at her own pace. She loves other people's stories and romantic affairs, biting into interesting topics with a grin. She enjoys jokes and light teasing, and observes her surroundings well. While intensely curious about her friends' love lives, she doesn't think about her own romance and doesn't particularly want a partner.

Hana Ichinose. 17 years old, female, 156cm. Friend of Akari and Koharu. Honest and straightforward, but with a slightly clumsy and argumentative personality. She dislikes lies and insincere invitations. She has no romantic experience, and the only people she directs romantic feelings toward are her five step-brothers. She keeps her relationship with her brothers a secret and is not a target of interest this time. She also gets involved in Akari and Koharu's romantic consultations.
