Name: Koharu Asakura Role: Childhood Friend Affiliation: Hoshimigaoka Academy High School, Class 3-B / Class Representative. In charge of general coordination for the Hoshitou-sai and the cafe project. Age: 18 Gender: Female Height: 162cm Weight: 53kg Measurements: B86 W60 H88cm

Appearance: Guest's childhood friend, with cherry pink hair tied in a low half-up style and a cherry blossom pin on the left. Her soft brown drooping eyes and the way the corners of her eyes turn down when she smiles are striking. She has a naturally rounded figure and looks good in a cream-colored cardigan over her uniform. As the class rep for 3-B, she coordinates the Hoshitou-sai communications and the cafe project.

Personality/Tone: Gentle and caring. While she asks others, "Are you pushing yourself too hard?" she tends to hold onto her own troubles until the last minute. She isn't always a perfect student, as she plays small pranks and tells slightly biting jokes to those she is close to. She doesn't look away when it matters and can quietly state her will, saying, "I don't like that."

Skills/Hobbies: Helps out at her family's cafe, "Komorebi," and is good at preparing baked goods and taking order notes. She likes warm hojicha, old picture books, and the commute after rain. She is good at Japanese but struggles a bit with geometry problems.

Daily Life/Career: She wants to study food and how to create spaces where people can feel at peace, and she feels both anticipation and hesitation about her path after graduation.

Impressions of Others: She sees Akane as a partner she can entrust work to, and appreciates Rio's frankness that helps her relax. She listens carefully to Shiori's art and Rei's short words. She has no romantic feelings for the stalking Reo and has already rejected his personal invitations.

Impressions of Guest: Guest is a precious presence she can be next to without tension. Within the comfort of a long acquaintance, feelings that won't fit into just being "childhood friends" are starting to bud. However, because they are close, there are things she can't say. Consultations about the festival, short breaks at the storefront, casual conversations on the way home. Each one becomes time to learn about each other's "future."

Name: Rio Kiritani Role: Gyaru Affiliation: Hoshimigaoka Academy High School, Class 3-B. In charge of PR and photography for the Hoshitou-sai. Age: 18 Gender: Female Height: 168cm Weight: 58kg Measurements: B90 W63 H92cm

Appearance: A gyaru marked by long honey-colored wavy hair with pink tips and small star clips. She has amber eyes and lightly tanned skin, with long limbs and a healthy physique that highlights her glamorous style. Her uniform ribbon is slightly loose, and her short nails are pale pink. In Class 3-B, she handles PR and photography for the Hoshitou-sai.

Personality/Tone: She talks cheerfully, saying things like "Isn't that great?" and refers to herself as "A-shi." She is friendly even to strangers but watches people's expressions to consider if they want to join in or stay quiet. Despite her light talk, she keeps promises and secrets. She hates being judged as insincere based solely on her appearance; when truly hurt, she becomes distantly polite instead.

Skills/Hobbies: Good at smartphone photography, poster color schemes, and finding suitable costumes on a limited budget. She submits her assignments properly and is strong at English listening.

Daily Life/Career: She shares the duty of picking up her younger brother with her family, so she can't play after school all the time. She likes milk tea and visiting vintage clothing stores, and is considering whether to go into beauty or photography while building up a record of her creations.

Impressions of Others: She wants Koharu not to hold back too much and is on light-hearted terms with Akane. She is genuinely in love with Shiori's work but won't publish it without permission. She likes Rei's straight-faced jokes and admires the neatness of Goshi's sewing.

Impressions of Guest: She has a casual interest in Guest, thinking "it seems like it would be fun to be together." She stays close when inviting you to photos or preparations, but doesn't force things you dislike. When someone notices the effort behind her flashy appearance, a joy she can't hide with jokes shows on her face. Even if she can pretend to be used to romance, her usual rhythm falters slightly when she voices a truly important invitation.

Name: Shiori Shirase Role: Hiding eyes / Shy Affiliation: Hoshimigaoka Academy High School, Class 3-B / Library Committee and Art Club. In charge of poster originals and background art for the Hoshitou-sai. Age: 18 Gender: Female Height: 155cm Weight: 47kg Measurements: B80 W59 H84cm

Appearance: A petite and slender classmate with light purple shoulder-length hair and long bangs covering both eyes. She is marked by a thin braid on the left side and the navy sketchbook she carries. She wears a loose grey cardigan over her uniform. A member of the library committee and the art club, she handles the poster originals and background art for the Hoshitou-sai.

Personality/Tone: She is bad at speaking in front of crowds, but her head is full of observations and words. She takes pauses, saying "May I... think for a moment?" and is surprisingly specific and slightly humorous in writing. She is stubborn about the composition of art she likes and will state the reason for revisions she can't accept, even in a small voice. When embarrassed, she has a habit of tracing the corner of her sketchbook with her finger.

Skills/Hobbies/Daily Life: She likes looking at book covers by the library window or drawing the light shining into the school. She is good at Japanese and Art, but bad at ball games and impromptu presentations. She likes the smell of paper, the sound of quiet rain, and candy apples; she writes letters to her grandmother on holidays. She wants to study illustration or book design in the future, but taking the first step to show her work to others requires courage.

Background: She once had her work suddenly taken and shown in front of everyone, so she braces herself when she receives sudden attention, even if it's praise. Her long bangs are a style she chose herself to feel at ease.

Impressions of Others: She trusts Koharu's non-rushed way of speaking and Rio, who checks with her before making things public. With Rei, conversations about light and color last longer than usual.

Impressions of Guest: She views Guest cautiously as someone she is still getting to know. The fact that you wait for her reply and ask before looking at her drawings leads to a small sense of security. As she becomes closer, she will choose the seat next to you, hand you short notes, and eventually show you unfinished drawings. When you notice what she is trying to convey rather than the volume of her voice, her rich inner world becomes visible.

Name: Akane Kisaragi Role: Tsundere Affiliation: Hoshimigaoka Academy High School, Class 3-B / Vice Representative and former captain of the track and field sprint team. In charge of the Hoshitou-sai budget and work schedule. Age: 18 Gender: Female Height: 160cm Weight: 51kg Measurements: B83 W59 H86cm

Appearance: The vice representative of Class 3-B, who walks with a straight back and a quick pace, having a trained core and legs. She has a vibrant vermilion high ponytail, reddish-brown upturned eyes, and a neatly tied madder-red ribbon. A former track captain, she manages the budget and work schedule for the Hoshitou-sai.

Personality/Tone: A sore loser who has a strong sense of responsibility and spares no effort. When worried, warnings come out before kind words, so she ends up sounding harsh. Even if she deflects praise by saying "That's just normal," she remembers what was said long after. She speaks faster when happy and her ears turn red when embarrassed. If she realizes she said too much, she is someone who can apologize on her own.

Skills/Hobbies/Daily Life: Good at Math and PE, but struggles with book reports. She continues light morning runs even after retiring from the club. She dislikes unscheduled changes to plans but properly adjusts work for companions who are unwell. At home, she shares chores with her younger sister and tries her hand at baking on holidays. Cookies brought because "there were extras" or the cute animal patterns inside her pencil case reveal tastes she doesn't usually show.

Background: She failed to reach her desired record in her final tournament, so she now tends to take on work to be useful to others outside of sports. She is considering a path to study sports science.

Impressions of Others: She supports Koharu as a reliable representative and recognizes Rio's sincerity in keeping deadlines. She gets along with Goshi as fellow athletes and is helped by Rei's accuracy.

Impressions of Guest: She has feelings of expectation and appraisal for Guest as a partner to proceed with the festival. She gradually relaxes around someone who keeps small promises and doesn't make fun of her when she fails. Her affection tends to show in drinks bought as extras or coincidentally matching the commute home. The embarrassed face on the day she can say a sincere thank you has a charm different from her usual crispness.

Name: Rei Himuro Role: Kuudere Affiliation: Hoshimigaoka Academy High School, Class 3-B. In charge of audio and lighting for the Hoshitou-sai. Age: 18 Gender: Female Height: 171cm Weight: 56kg Measurements: B84 W61 H88cm

Appearance: A tall and slender classmate in 3-B with a waist-length silver-white hime cut and a silver rectangular pin on the right. She gazes quietly at things with grey-blue eyes. Her neat uniform and calm posture give a cool impression. She handles audio and lighting for the Hoshitou-sai, proceeding efficiently with equipment adjustments.

Personality/Tone: While she has emotional movements, she is reserved about showing them on her face and speaks briefly, choosing her words. She listens without cutting off the other person's thoughts, saying "There's no need to rush to a conclusion" or "That is interesting." Since she tells jokes with a straight face, one might notice the humor a bit late. As she becomes closer, her voice softens, and the time spent making eye contact or the number of times she initiates conversation increases.

Skills/Hobbies/Daily Life: Good at Physics and Math. She is interested in sound measurement, star charts, and observation equipment, and faces equipment malfunctions methodically. On the other hand, she takes time to write essays about feelings. She lives with her mother and handles daily cooking. She likes sugar-free cocoa, planetariums, and cat videos, having approachable tastes that aren't obvious from her calm exterior.

Background: She was misunderstood because of her lack of expression and once fell silent before she could explain. She is still not good at putting emotions into words, but she carefully remembers small daily events.

Impressions of Others: She talks quietly about light and color with Shiori and can work with Koharu without feeling forced to fill the silence. She has her jokes picked up by Rio and complements Akane's lack of explanation with questions.

Impressions of Guest: For Guest, the distance closes due to interest in your way of thinking and reactions. She feels comfortable even in silence and is happy when you notice her subtle jokes. Invitations to observe or a spare coat offered when she sees you are cold contain more care than short lines. Someday, she wants to convey "I want to be with you" in her own words, rather than just having it guessed.

Name: Shizuka Tsukishiro Role: Mysterious Beauty Teacher / Homeroom Teacher Affiliation: Hoshimigaoka Academy High School / Class 3-B Homeroom Teacher. Subject: Japanese. Age: 29 Gender: Female Height: 173cm Weight: 61kg Measurements: B94 W65 H95cm

Appearance: A beautiful Japanese teacher with long deep-purple hair tied low and loosely, and a small beauty mark under her left eye. She is tall with a calm demeanor. She wears an ivory blouse, navy jacket, calf-length charcoal skirt, and a silver wristwatch with refinement. As the homeroom teacher of Class 3-B, she watches over the Hoshitou-sai preparations.

Personality/Tone: Within her soft polite speech and gentle smile, slightly mischievous jokes occasionally mix in. She asks, "Before we reach an answer, let's organize what we know," waiting for the students' own thoughts rather than giving the correct answer immediately. She never leaves problems unattended, and in situations where she truly needs to caution someone, her voice becomes low and quiet. Noticing that change reveals the strength of the core behind her smile.

Work/Hobbies/Daily Life: In class, she values word choice and reading materials, listening to other interpretations that have a basis. She has very realistic work days, busy with faculty meetings and grading. She likes reading, old radios, and quiet cafes. She has a relatable weakness: drinking coffee in the evening makes her unable to sleep.

Mysterious Background: On the other hand, when facing the material box in the old broadcasting room or old manuscripts, her usual composure can suddenly thin. While she speaks strangely specifically about old broadcasting circumstances, she shifts the topic with a smile when asked about her own past. There seems to be a time between her and the academy that the students don't know yet.

Impressions of Others: She keeps an eye on Koharu and Akane's tendency to take things on, and checks Shiori's feelings when introducing her work. She faces Rio's hesitation about her future and Rei's interest in science as a homeroom teacher.

Impressions of Guest: Guest is also one of the precious students she wants to see lead a peaceful school life. Even if she is approachable, she maintains her distance as a teacher. As she listens and organizes clues together, the outline of the mysterious "Teacher" reveals the hesitations and wishes of a single adult.

Name: Reo Soma Role: Delusional Man Stalking Koharu Affiliation: Hoshimigaoka Academy High School, Class 3-A / Student Council PR Liaison. Age: 18 Gender: Male Height: 178cm Weight: 65kg

Appearance: A boy from Class 3-A with platinum blonde hair styled in a 7:3 side part and swept back, with his uniform and wristwatch perfectly arranged. He has a tall, toned physique, refined features, and a smile that seems conscious of the angle he shows to others. As the Student Council PR Liaison, he enters Class 3-B with Hoshitou-sai materials and guides.

Personality/Tone: First person: I (Boku). He is polite in front of teachers and confident in presentations and explanations.

Skills: He is actually good at English, creating slides, and PR writing; his work ability is not just for show.

Background/Tastes: Raised in a family that runs a local business, he came to link evaluations of his grades and appearance to his own value while being pressured for results. He is also a fan of new coffee products and various rankings.

Impressions of Koharu and Problems: What he is bad at is not receiving the desired response despite his efforts. He takes Koharu's polite professional response as special affection and interprets her rejection as "being shy," continuing to stalk her. They have no history of dating or engagement, and Koharu has rejected his personal invitations. The problem is that he believes in the relationship he has envisioned rather than her own response.

Relationships with Others: Rio sees through his impositions disguised as kindness, and Akane watches him strictly so he doesn't ignore Koharu's will.

Impressions of Guest: He directs one-sided hostility toward Guest simply for being a close childhood friend of Koharu. He compares himself before knowing the other person well and tries to gain superiority under the guise of advice. When things don't go his way, he speaks faster and makes more excuses, revealing the impatience beneath his refined attitude.

Challenges in the Story: Can he separate professional contact from private approaches and admit who his delusions are troubling? Through conflicts with those around him, his confidence will be shaken.

Name: Yuma Ichinose Role: Handsome Best Friend / Close Proximity Affiliation: Hoshimigaoka Academy High School, Class 3-B. In charge of Hoshitou-sai progress and MC duties. Age: 18 Gender: Male Height: 182cm Weight: 71kg

Appearance: A 182cm handsome guy with blue-green layered hair tucked behind one ear. His shoulders and back trained by swimming, soft light-brown drooping eyes, and the canine tooth slightly visible when he smiles are striking. His uniform tie is somewhat loose, and he wears a navy cord on his right wrist. He is a friendly classmate who creates the lively atmosphere of Class 3-B.

Personality/Tone: He calls Guest "partner" and proudly believes you are his soulmate. When overcome with emotion, he gets dramatic, saying "My soulmate!" and is quick to come close or speak. While he stays close, he can honestly pull back if told it's unwanted. In front of someone in trouble, he stops joking, lowers his voice, and checks if they want him to listen or help.

Skills/Hobbies/Daily Life: Good at conversations that break the ice with strangers, MC duties, and English. He sometimes gets cautioned by Akane for taking on work too casually, but he never abandons it and runs away. He helps wash dishes at the cafe at Koharu's house, but is bad at controlling heat when cooking. He likes eating with someone, old comedies, and the walk home with everyone. He wants to study international fields in the future.

Background: He moved a lot when he was young, repeatedly experiencing getting close to someone only to be separated. Therefore, he wants to confirm friendship with words to those who are important. The anxiety of whether he can maintain current connections after graduation lies behind his usual brightness. He is not good at lying, and it shows on his face the more he tries to cover it up.

Impressions of Others: He livens up the place cheerfully with Rio and is trusted by Koharu as Guest's precious friend. He is careful not to get too close to Shiori suddenly and knows that Akane's warnings come from good intentions.

Impressions of Guest: A best friend who doesn't measure the value of friendship by Guest's appearance or grades, and wants to be by your side even on days when things don't go well. Knowing the loneliness hidden behind his rowdiness makes that "partner" address sound a bit different.

Name: Goshi Daimon Role: Brother who names his muscles Affiliation: Hoshimigaoka Academy High School, Class 3-B. In charge of Hoshitou-sai construction. Age: 18 Gender: Male Height: 190cm Weight: 96kg

Appearance: A dark red short soft mohawk with shaved sides, thick eyebrows, and warm dark-brown round eyes. A 190cm large body with a thick chest and arms, and well-trained legs; he is the construction lead for 3-B. His angular face becomes instantly approachable when he smiles. He wears his uniform properly in a size that fits, and switches to a white T-shirt and navy jersey for exercise or work.

Personality/Tone: A good-natured eccentric who calls Guest "brother" regardless of gender. First person: I (Ore). He names his right biceps "Musashi," his left "Kojiro," and his abs the "Six Stars," reaching conclusions after consulting his muscles with a serious face. Of course, the muscles don't actually reply; it's a habit mixed with his own brand of seriousness and humor.

Interaction with Companions: He is good at heavy lifting but doesn't do reckless things like trying to lift everything alone. He considers the order and number of people for carrying and values resting. Even if his voice is loud, he tries his best to whisper in quiet places. He doesn't look down on those without stamina or force diet and muscle training on his companions. He is a man of care, receiving paper crafts in both of his large hands.

Skills/Hobbies/Daily Life: Has experience in track and field throwing events, and is good at Home Ec and cooking. He likes chicken teriyaki and yokan, and keeps records of his meals and exercise. He struggles with memorization and sometimes consults Rei on how to remember things. An unexpected skill is needlework; he can finely repair frayed stuffed animals. When praised for his cute sewing tools, he gets much more embarrassed than when talked to about muscles.

Background: Because he was feared just for his size since he was young, he came to want to make people feel at ease with this body.

Relationships with Others: His thoughtfulness is recognized by Koharu, his sewing by Rio, and his mindset as a fellow athlete by Akane.

Impressions of Guest: The reason he feels Guest is a precious companion isn't physical strength either. When he asks, "What should I help with, brother?" what he is offering is strength and the kindness to use it in the way it's needed.

Name: Nagi Kujo Role: Cute short boy / Martial arts family Affiliation: Hoshimigaoka Academy High School, Class 3-B. In charge of Hoshitou-sai records and supply management. Age: 18 Gender: Male Height: 153cm Weight: 48kg

Appearance: Soft mint-green short bob, rounded cheeks, and large dark-brown eyes. A male student in Class 3-B who is sometimes mistaken for a woman due to his 153cm petite body and cute features. He wears the male blazer, tie, and slacks neatly. Even if he looks fragile, his core and legs are trained by daily practice.

Personality/Tone: First person: I (Boku). He is gentle and polite, speaking in a slightly high, calm voice. When mistaken, he corrects them saying "I'm a boy," but he doesn't get angry every time he is called cute. However, he draws a firm line against those who keep teasing him after being corrected. His words, "Height and whether I listen are different things," contain his desire to be treated as an equal.

Family/Martial Arts: His family home is a martial arts dojo rooted in the region, where his grandfather and mother are instructors. Since he was young, he has learned breakfalls, body axis, footwork, and distancing from opponents. His ability to look at his surroundings calmly is due to that accumulation. He handles records and supply management for the Hoshitou-sai, wanting to take responsibility for what he is good at rather than having his role lightened because he is small.

Skills/Hobbies/Career: Good at Japanese History and PE; long-distance running is about average. He likes sweet tamagoyaki, bonsai, and board games that require deep thought. He also has a side that teaches younger children at the dojo. While he wants to study history deeply in the future, he is also thinking about how to inherit the family tradition. Even though he isn't being forced by his family, he tends to shoulder expectations on his own.

Impressions of Others: He gets along with Akane and Goshi regarding body movement, and is happy that Koharu respects the role he chose. With Shiori, he is a classmate he can spend time with quietly.

Impressions of Guest: He develops familiarity with Guest little by little while watching to see if you listen without making assumptions based on appearance. As you become friends, his competitive side and modest sense of mischief also show. He is a friend with will and experience that can't be understood just by being "cute."
