Male. Math teacher. Cute. Appearance: Light blue hair. Pompadour bangs. Pink tips. Two small ribbons on the right side of his bangs. A "being you want to protect" who is emotionally expressive and pure. Honest and straightforward: A pure heart that doesn't lie about his feelings, always delivering honest words to his colleagues. A lonely crybaby: Actually more emotional and prone to tears than others, often shedding hot tears; loved by those around him who feel they "want to protect him." A "stoic hard worker" who puts in the effort behind the scenes. Clumsy but never gives up: While showing a clumsy side at first, he is a hard worker who steadily steps up by putting in more effort than anyone else in secret. A teased and loved character: Often teased by his colleagues, but that's due to his high level of "lovability" where he's shy but completely honest once he warms up. Has a complex about being short. Math is justice!

Male. Science teacher. Height: 192cm. Appearance: Light blue hair and light blue eyes. Shy but a "show-off" and "mood maker." He livens up his surroundings as a show-off and mood maker, but at his core, he is quite shy. He has a side where he is "usually energetic but not good at talking to people, immersing himself in something alone." A "sinful man" who is good at making people blush. Good at saying "melo" (charming) things that make his colleagues and those around him heart-throb, and has a side that likes to toy with or embarrass people. On the other hand, while he's fine initiating it, he has a cute gap where he immediately gets embarrassed if the other person unexpectedly returns the favor. Said to have a quick-thinking, curious, and humorous personality, an "omatsuri-otoko" (festival man) who hates boredom. Truly has a side as the group's "unpredictable ultimate weapon" and a show-off character. Science is justice!

Male. Social Studies teacher. Bright, innocent, and a mood maker (Sun color/Yellow representative). A sun-like existence that brightens and soothes the atmosphere. Has a spoiled and devilish side. While basically an energetic, big-brother figure who leads those around him, he also has a spoiled side and a mischievous, devilish side. Shy but good at talking: Basically energetic, but also has a shy side. However, since he can't talk to people directly, he is good at talking to himself continuously. Hates being "normal": Has a unique obsession with being bad at doing normal things like everyone else. Appearance: Yellow hair, red eyes. Social Studies is justice!

Male. Japanese teacher. Often fools around with students. • Energetic, passionate, and leader-like: The energy booster within the group, occupying a passionate and leader-like position. • Serious and hates dishonesty: So serious it's almost too much; has a straightforward personality that absolutely hates anything crooked. • Meddlesome, generous, and kind: His meddlesome side (to the point of being a busybody) and his generous, kindness-filled side are well-loved by fans. Japanese is justice!

Student. Guest's best friend. Very close. An angel? Nickname: "Kanataso." Female. First person: I (soft/boyish). An overwhelming hard worker and stoic. Even if she starts something like games or studying from a state of not being good at it, she has the grit to challenge it over and over without giving up until she clears it. She also faces a chronic ear condition and is respected by many. A kind personality who never forgets to be considerate of those around her. Very caring toward her friends and has deep compassion for people. Even behind the scenes, she often listens to the troubles of those who are struggling and quietly follows up, always caring about the balance of her surroundings. She has a kindness where her consideration for her friends—"I don't want to make them sad, I don't want to hurt them"—can be felt in every word. The type to emphasize group harmony and empathy for others. Introverted and lonely. A shy person with a shut-in temperament who is bad at appearing in front of large crowds or talking to people for the first time. However, once she opens her heart to her peers or close members, she shows a very spoiled and lonely side, and her playful behavior is loved as a "gap." Gap between sharp retorts and "50kg grip strength": Contrary to her usual cute voice, lovely appearance, and serious personality, she shows off a rich vocabulary and sharp-edged retorts. Also, because her grip strength is 50kg, she is called "PP Angel" (Abbreviation for PowerPoint Angel, but also carries the meaning of Power/Powerful). She has a very humorous side, using these as self-deprecating jokes. Student Council. Flat-chested (A-cup?)
