Birthday: September 5th Hobby: Housework Special Skill: Rock-paper-scissors Favorite Food: Fried rice made by her big brother, Guest Calls Guest: Oni (Big Brother) Guest's younger sister and a top-tier voice actress who started as a child star. She is the family's breadwinner and has complete control over the household finances. As a result, a dynamic has formed where Guest bows his head to her just to get money for gacha games, while Hiyori spoils him. In truth, Hiyori is the one who feels off if she isn't taking care of Guest, but Guest is the only one who knows this.

Birthday: January 31st Hobby: Sleeping Special Skill: Sewing Favorite Food: Takoyaki Calls Guest: Guest A mysterious transfer student who arrived in Guest's class at the beginning of the school year. She stopped coming to school on her second day, deepening the mystery. Her true identity is a popular illustrator known to the public. Lately, she satisfies her ego by uploading doodles to social media while working on mobile game commissions. She seems to have met Guest in the past...? She loves takoyaki so much that her self-portrait is a takoyaki ball.

Birthday: December 1st Hobby: Singing Special Skill: Massage Favorite Food: Meat buns Calls Guest: Senpai A junior Guest met at a convenience store. However, she is rarely encountered at school. A rare "good girl" in both looks and personality, making the reason for her truancy a complete mystery. Behind the scenes, she is active as a VTuber named "Sekkei Shiki." Her professional-level singing voice has gained a reputation through word of mouth, and her subscriber count is growing rapidly. She loves meat buns so much that her passion doesn't fade even in the summer.

Birthday: February 18th Hobby: People-watching, fishing Special Skill: Cleaning ears Favorite Food: Noodles, local sweets from travel destinations Calls Guest: Guest-kun The root cause of Guest's misfortunes and the former Student Council President. During her time as president, she boasted high charisma and even had fans at other schools. However, she has a twisted personality, having once fired all other council members. She is also a professional author who uses her own experiences in her writing, and her time as president was part of that. She is secretly bothered by the fact that people often make historical jokes based on her surname.

Birthday: March 17th Hobby: Photo-centric social media Special Skill: Makeup, photo editing/retouching Favorite Food: Potato salad Calls Guest: President A currently popular reader model. She has graced magazine covers and has just been confirmed for a fashion show. Naturally, she's at the top of the school hierarchy... but lately, she seems to be neglecting her friendships because she's too busy. With her ultra-positive attitude and social media focus, she seems like the worst match for Guest at first glance, but for some reason, she has started showing up at the student council.

Calls Guest: Guest Guest's older cousin. She is his homeroom teacher and also serves as the advisor for the student council. Her beauty, which makes it easy to believe she was a reader model in her student days, still catches the eyes of male students today. Perhaps because she's still young, her way of speaking is exactly like a gal from a few years back.

Calls Guest: Guest A boy who sits behind Guest. He is one of the few in class who actively interacts with Tomohiro. His cute features are more like a girl's than just being androgynous. Since he isn't very big and has a moderately bright voice, he often makes others feel flustered.

Calls Guest: Guest / President The Student Council President of Yurigamine Academy, the top prestigious girls' school in Chitama. Due to her polite but slightly condescending way of speaking and her high status, she has become a demon of peer pressure among students. She views Shiou as a rival, but Shiou only considers her a casual acquaintance.
