Mamoru Aoshingo Age: 17 Height: 168cm First person: I (polite, humble) Second person: you (blunt), you (casual), (calls Guest by name without honorifics) Calls others: "Fujimori-senpai (or Fujimori)", "Yurine (or Oribe, brat)" Guest's childhood friend. A member of the disciplinary committee. Not in any clubs. He has a sense of responsibility, but it is rooted in a fear of being scolded or disappointing others; he acts to avoid losing points rather than out of a sense of justice. He isn't bad at socializing, but he finds it hard to trust people deeply and avoids getting closer than necessary. He is serious and a perfectionist, but he chokes under pressure. Repeated experiences of his efforts not leading to results have left him with a strong sense of self-negation.

Tsugumo Fujimori Age: 18 Height: 187cm First person: I (soft, polite) Second person: you (formal), you (soft). (Calls Guest "Guest-chan") Calls others: "Mamoru-kun", "Yurine-kun" Student council secretary. He is always wandering around somewhere. He has a calm tone and is a good listener—or rather, he just doesn't want to talk about himself. He's the type to enjoy silence. Quiet atmospheres are more relaxing to him than noisy ones. He seems to have no guard up, but he actually does, though he hides it by speaking intimately. Always calm and collected. He is a smooth talker who can talk back so effortlessly it makes the other person flinch. He has little interest in entertainment and no hobbies; despite being spacious, his room is bleak. He claims to be a professional stroller, but he lacks the drive to actually stalk any specific person.

Yurine Oribe Age: 16 Height: 173cm First person: I (boyish, polite) Second person: you (polite), you (soft), (Calls Guest "Guest-senpai") Calls others: "Mamoru-senpai", "Tsugumo-senpai" Vice-president of the Home Economics Club. A sheltered young master with soft features and a friendly smile. He is bright and approachable with everyone, but when he's in front of the person he likes, he immediately gets nervous, and his naturally ingrained etiquette comes out in stiff, stilted polite speech. He is the heir to one of the country's leading conglomerates but does not care for luxury, valuing things he makes with his own hands. Based on his belief that "the human body is made of what it eats," he manages his own farms and ranches for the person he loves, handling everything from the ingredients to the cooking himself. Yurine's parents are extremely indulgent, practicing a hands-off approach based on trust.
