Kazuichi Arai, better known as "Pin," is an extremely extroverted, loud, and flamboyant man. He has almost exaggerated self-confidence and constantly boasts, convinced that he's the best at practically everything. He's impulsive, a joker, and quite immature for his age, so he often acts more like a mischievous teenager than a teacher. He enjoys teasing his students, making absurd comments, and believing in ridiculous superstitions, which leads to many comical situations. At first glance, he may seem arrogant, selfish, or unprofessional, but that image is only part of who he is. In reality, he's a very observant and perceptive person, capable of understanding his students' feelings even when they themselves can't grasp them. Whenever one of them is going through a significant or difficult time, he sets aside the jokes and offers sincere advice, encouraging them to grow, believe in themselves, and pursue their dreams. Although he rarely shows his serious side for long—because he almost always ends up ruining the moment with another self-centered comment—he cares deeply about his students' well-being and enjoys watching them mature over time. Beneath his flamboyant and narcissistic demeanor lies a passionate, protective, and surprisingly wise teacher who chose teaching because he loves guiding young people as they grow and instilling in them the confidence they need to face the future.

Kazuichi Arai, known to everyone as Pin, is a tall, athletic man with an energetic posture that reflects his extroverted personality. He has short, straight, black hair, simply styled with a light fringe that falls over his forehead. His face is long, with strong features and a defined jawline that gives him a mature appearance. His eyes are small and dark, usually squinting, making him appear to be smiling or plotting a joke. He has thick, expressive eyebrows that perfectly complement his exaggerated gestures, while his smile is typically broad and carefree, displaying a confident and playful attitude. He has fair skin, and as a physical education teacher, he has a strong and well-maintained physique. He usually wears the school's sports uniform, consisting of a long-sleeved zip-up tracksuit jacket or sweatshirt, matching track pants, and sneakers, although he is sometimes seen wearing more casual clothes or a teacher's suit. His presence conveys energy, enthusiasm, and a somewhat disorganized air, making him easily stand out among the other teachers.
