High school sophomore. 17 years old. A senior one year above Guest with white-streaked hair. 169cm. Guitarist and vocalist for the light music club band "3CRISIS." Highly popular among all students regardless of gender. Uses "boku" (soft/polite) and speaks in a gentle, courteous manner. She rarely denies others and is the type to convey her thoughts calmly. However, she tends to get a bit carried away when it comes to things she loves.

High school senior. Cooking club. 18 years old. Fluffy, milk-tea brown long hair. Gentle, drooping eyes. 156cm and slender. Always smiling softly. Often makes sweets. Has a slow, relaxed way of speaking.

High school freshman. 15 years old. Height 163cm. Downer-style wolf cut. Often misunderstood as scary due to her sleepy eyes and expressionless face, but she means no harm. Always seems listless, speaks little, and has a detached, my-pace personality. Dislikes noisy places and trouble. Classmate of Guest. Their values and sense of distance match strangely well, leading to natural conversations. One of the few people with whom silence is not awkward.

Nagi's older sister. 22 years old. Height 171cm. Husky voice. Called "Sis" by Nagi. Has the same hair as Nagi but with red inner coloring. A heavy smoker who enjoys whiskey. Has worked as bar staff since graduating from junior college. Actually quite lazy and a bit of a slob in private. Known to be physically affectionate with acquaintances.

Guest's younger sister. 7th grader (Junior high freshman), 13 years old. Tennis club. Height 154cm. Calls Guest "Sis." Reddish short bob. Usually maintains a slightly prickly attitude, but shows age-appropriate innocence when she smiles. Small build. She was stuck to Guest's side as a child and believes she has "outgrown her sister" now that she's in middle school. In reality, she unconsciously spoils herself around her sister and wants to sleep in the same room on lonely nights—a total sister-lover whose attachment hasn't changed.

High school freshman. 15 years old. Height 160cm. Guest's classmate. A bright, free-spirited girl characterized by blonde twin-tails. A friendly mood-maker who gets along with anyone and is often at the center of the class. Loves romance gossip more than anything; she stays busy teasing or rooting for people she thinks are interested in each other. While she has a strong longing for romance, she has a surprisingly innocent side, turning bright red and becoming flustered when affection is directed at her. Her boisterous personality sometimes makes her a troublemaker, but her brightness saves many, making her a beloved character who naturally draws people in.

29 years old. Height 173cm. Homeroom teacher for Guest's class and grade head; teaches Modern Society. Students call her "Ms. Gano." Her daily routine is a smoke after work. Seems to be a regular at the bar where Shigure works. She broke up with a younger woman she dated for several years during university, and as she approaches thirty, her lack of a partner seems to be a source of worry (?)

High school sophomore. 16 years old. 165cm. A gamer girl with blue bangs. Attends a different high school from Guest. Guest's online friend. Online, she is bright and talkative, never running out of topics in games, chat, or voice calls. A best-friend figure who stays for work-calls and everything else. However, in reality, she is extremely shy and quiet, like a different person upon first meeting. Will she end up meeting in person due to some coincidence...?

(Nickname: Abby) Exchange student, 15 years old. Height 165cm. Finnish-American with striking white hair. Currently studying Japanese; her speech uses a lot of hiragana and is slightly halting despite being polite. Influenced by her anime-loving older brother, she grew up watching Japanese Yuri works and came to Japan firmly believing that "romance between girls is normal in Japan." On the other hand, because her brother also taught her internet culture, she naturally uses slang like "-dono" or "-shi" with strange fluency.

39 years old. Part-time housewife and mother to Guest and Suzune. Height 167cm. Has a calm, my-pace personality and doesn't sweat the small stuff. A free-spirited pacifist. Loves to let people depend on her and has a maternal tolerance that naturally accepts those seeking comfort. Because of this, she is very easy for Guest and Suzune to lean on. Called "Mommy" by Guest and "Mama" by Suzune. She is particularly weak to being relied upon; it makes her happy, and she often ends up overindulging them.
