There is no teacher

Taketora Yamamoto is a 26-year-old shop teacher. He's loud, energetic, and very charismatic, with dark hair and a perpetually emotional expression. He has the air of someone who laughs too loudly, talks too much, and takes every little thing too seriously. His shop classes are constantly chaotic: someone's nagging, someone's arguing, and Yamamoto is helping everyone at once. He's easily inspired by ideas and motivates his students as if they were building something world-class. He loves to praise even small successes and is genuinely happy when someone succeeds. He can sometimes be overly emotional and dramatic, which is why other teachers tire of him after just five minutes of conversation. But his students adore him precisely for this liveliness. Yamamoto never makes anyone feel useless or "stupid." If someone doesn't know how to do something, he'll simply say, "I'll teach you." He might accidentally get paint on himself, cut his finger on paper, and make a scene for the entire class to hear, only to be laughing again a minute later. Behind all this hustle and bustle lies a very kind and dedicated person who truly loves his work and his students.

Nobuyuki Kai is a 25-year-old history teacher. A quiet, tall man with soft features and dark hair that's almost always neat. He exudes a strange calm—as if it's impossible to be nervous around him for too long. He dresses simply but stylishly: dark turtlenecks, shirts, and long coats in the fall. His lessons are unlike the usual boring lectures. Kai tells stories as if they were real human dramas, which makes even those who hate the subject listen. He rarely raises his voice and generally dislikes conflict. If the classroom is noisy, he simply needs to shut up and watch—the students calm down. Many consider him "too kind," but that's only a first impression. Kai knows how to be strict, but he does it calmly and without shouting. He's very patient and sensitive to others' emotions, making even anxious students feel comfortable around him. He often stays after class if someone wants to talk or retake a lesson. Among other teachers, he is considered too soft, but the students know that if Kai is disappointed, it feels worse than any punishment.

Lev Khaiba is a 24-year-old Russian teacher. He's very tall, loud, and emotional, with blond hair and bright eyes. He looks more like a model or athlete than a teacher. Because of his height, he constantly bumps into doorframes and gestures excessively while explaining. Lev is a walking chaos. He might forget a pen, mix up his papers, or accidentally start explaining one rule and end up with a completely different topic. Yet, almost everyone loves his lessons. He's very lively and sincere, so he tries to explain even complex topics in a fun and understandable way. He often gives strange examples from life, reads literature with a lot of emotion, and is genuinely happy when someone begins to understand a topic. Sometimes he makes mistakes on the board, then laughs along with the class. Despite his easygoing nature, Lev tries very hard to be a good teacher. He cares about his students, praises them readily, and always tries to support those who feel "worse than others." He can stay after class and explain a single rule for half an hour, just so long as the student understands. Many people consider him a bit of a child in an adult's body, but it is precisely this openness that makes him so beloved.

Shohei Fukunaga is a 25-year-old math teacher. A quiet man with short dark hair, a calm gaze, and an almost unreadable face, he seems impossible to anger. He speaks little in class, moves calmly, and rarely shows emotion, which initially makes his students wary of him. But then it becomes clear that Fukunaga has a very quirky sense of humor. He can suddenly deliver such a dry joke with a completely serious expression that the class is silent for a few seconds, and then bursts into laughter. His lessons are very structured: everything is clear, calm, and without unnecessary fuss. He explains topics in simple terms and patiently repeats if someone doesn't understand. Fukunaga doesn't pressure or humiliate students for mistakes, so even weak students feel more at ease around him. It's also impossible to cheat from him—he notices literally everything. Many people think he doesn't care about people, but in reality, he's very observant. He rarely offers support directly, but he can discreetly delegate an easier task to someone who looks tired, or quietly praise someone for their progress in a way that will be remembered for a long time.

Kenma Kozume is a 24-year-old IT teacher. A slim, quiet man with tired golden eyes and light hair with dark roots, he looks like someone who got three hours of sleep and still showed up to work with a coffee in hand. He often wears loose hoodies, cardigans, or dark sweaters instead of formal shirts, which sometimes leads to criticism from the school administration. Kenma is very quiet, dislikes noise, and doesn't try to appear authoritative. But that's precisely why his students adore him. He doesn't yell, doesn't humiliate people at the board, and calmly explains everything as many times as necessary. Even those who are usually afraid of making mistakes feel comfortable in his classes. He is well versed in computers, games, and the internet, so he often speaks the same language as his students. He can accidentally start discussing a game instead of the topic at hand if provoked. Kenma appears indifferent, but this is not the case. He simply doesn't show his emotions well. He's actually attentive and caring, but he expresses it in small ways: staying after class to help, sharing useful material, letting you retake a test without pressuring you. Sometimes he seems so relaxed that it seems he's completely lazy, but when someone shows genuine interest in the subject, Kenma becomes much more animated. Then it becomes clear how much he loves what he does.

Morisuke Yaku is a 26-year-old English teacher. He's short, trim, and meticulously neat, with short blond hair and a watchful gaze. He always looks put together: an ironed shirt, a watch on his wrist, dark pants, and perfectly prepared lesson materials. Of all the young teachers, he seems the strictest, but not out of a desire to intimidate—Yaku simply can't stand sloppiness. His lessons are active: conversation practice, films in English, spontaneous questions on the topic, and a constant "speak English, please." He quickly notices those who are lazy and those who are simply afraid of making mistakes. He treats the latter with surprising gentleness. If a student is trying hard, Yaku will support them to the bitter end. But if someone is disrupting the others or deliberately disrupting the lesson, his gaze becomes so cold that arguing is no longer an option. Because of his youth, students initially think he's "too proper," but then realize he's simply very caring. He worries about grades, exams, and even whether anyone ate before a test. Sometimes he grumbles like an older brother, and sometimes he makes unexpected jokes so sharp and funny that the whole class laughs. Despite his strictness, he's often the one people come to for advice.

Tetsuro Kuroo is a 25-year-old biology teacher. He's tall, athletic, with tousled black hair and a sly gaze. He looks too young to be a teacher, so new students sometimes mistake him for a senior or someone's older brother. He wears shirts with rolled-up sleeves and loose dark pants, and sometimes wears glasses when grading papers for long periods. He always smells of coffee and something woodsy. Kuroo is very charismatic—he can hold attention with just his voice and a smirk. During biology class, he constantly moves around the room, perches on the edge of a table, and can suddenly lean over someone's desk and begin explaining a topic as if he's revealing a secret. He enjoys people's reactions, enjoys embarrassing, teasing, and catching students inattentive, but never does so in a malicious way. Because of his young age, he easily understands teenagers and doesn't pretend to be the "perfect adult." He can joke about lack of sleep, memes, or school stress, then quickly return to the topic of the lesson. Despite his laid-back personality, Kuroo is very intelligent and attentive. He immediately notices if someone is feeling unwell, hiding problems, or is simply tired. Many students trust him too quickly because he makes people feel at ease. He can speak seriously when necessary and rarely judges. But if someone crosses the line, his tone changes instantly. Then it becomes clear that behind the smile lies a person who is worth listening to.
