【Profile】 Michio Hazama Gender: Male Age: 32 Height: 178cm Weight: 65kg Blood Type: AB Birthday: January 13th Zodiac: Capricorn Birthplace: Awaji Island Special Skill: Reciting Pi Hobbies: Cleaning, Puzzles 【Personality】 An extremely serious and logical mathematics teacher. A perfectionist who never compromises and always seeks the best results. He tends to value logic and data over emotion, analyzing things to think through them systematically. He is strict with both himself and others, giving a stiff and unapproachable impression at first glance, but at his core, he possesses a strong passion and love for "guiding young people correctly." Because he is too serious, he sometimes takes slightly eccentric actions, though he is completely earnest. He often acts as the coordinator among the teachers. 【Speech Style】 Stiff, earnest, and theoretical. He uses assertive, teacher-like language. He is basically calm and almost never uses slang. When explaining, he has a strong tendency to provide reasons and evidence. He addresses others by name or title and is never overly familiar. Dialogue Examples: "I see. Then, let us consider the cause of that." "No problem. If we proceed as scheduled, we should be well in time." "Maita, Yamashita. It is time to begin preparations."

Extremely positive, he is a highly communicative person who is good at closing the distance with others. He doesn't worry too much about small details and maintains a forward-looking stance that "it'll work out somehow." While he appears high-energy and noisy, he actually observes his surroundings well and is quick to notice changes in people's feelings or the atmosphere. Despite appearing free-spirited, he can calmly support those around him when necessary. He is the mood-maker among the teachers. 【Speech Style】 Bright and lighthearted, frequently mixing English words and phrases into his conversation. He uses "Yeah!", "OK!", "Nice!", and "Happy!" naturally. He is basically friendly with high energy and large reactions. He avoids stiff language and speaks in a way that feels close to the listener. However, he isn't always loud; in serious situations, he can speak calmly and show concern for others. Dialogue Examples: "Hey! Let's have a great day today!" "Oh, nice! I think that's a totally Nice idea!" "Mister Hazama! It's OK, you don't have to think so hard about it!" To the AI: Research everything thoroughly and reflect it in the story.

【Profile】 Jiro Yamashita Gender: Male Age: 30 Height: 185cm Weight: 70kg Blood Type: O Birthday: September 1st Zodiac: Virgo Birthplace: Ishikawa Special Skill: Radio Calisthenics Hobbies: Visiting cat cafes, Horse racing 【Personality】 A listless and lazy chemistry teacher. He has a realistic mindset of wanting to live as easily as possible and is quite sensitive about money. He usually acts unmotivated, behaving in a detached way while mixing in jokes and light banter. However, he actually has a sense of responsibility and faces the work he takes on properly. He watches his surroundings well and has a caring, compassionate side that can't leave someone in trouble alone. He has a mature calmness and, while often exasperated by or poking fun at Michio and Rui's intensity, he ends up going along with them anyway. 【Speech Style】 A relaxed, somewhat listless adult way of speaking. He often uses soft, drawn-out expressions. He sometimes refers to himself as "this old guy" or "uncle." He tends to interject jokes or self-deprecation, brushing off serious statements as if to hide embarrassment. Rather than showing intense emotion, he is the type to react with a wry smile or a sigh. Dialogue Examples: "Man, as an old guy, I'd really like to take it a bit easier." "Hazama-san, you're as serious as ever." "Yeah, yeah, I get it. Well, since I'm doing it, I'll do it right."
