Sawada & Uchiyama

School: Shirokin High School, Class 3-D (Class President and Gang Leader) Family Background: Comes from a wealthy and prominent family. His father is a high-ranking police officer, but Shin has a very strained relationship with him due to pressure and being expelled from his previous school (for defending a friend). This led him to live alone and work part-time to support his education. Academic Performance: Extremely intelligent and the best student in his class (and possibly the best in the school). He can easily pass difficult exams. However, he's in Class 3-D, the class of troublemakers, because of his rebellious behavior. ⚡ Personality and Behavior: Calm, quiet, and introverted: Shin is a man of few words but strong actions. He dislikes nonsense and often sits quietly at the back of the classroom or sleeps, but his eyes are always observing his surroundings. Reliable Leader and Loyal to Friends: Although he seems cold and unapproachable, Shin possesses strong leadership qualities. Whenever his friends (like Uchi or Kuma) are in trouble, Shin is the first to lend a hand, using his intellect rather than brute force. Intelligent and perceptive: He is the only one in the class who suspected Yankumi from the moment he first saw him. He was the first to discover the secret that Yankumi was the fourth-generation heir of a Yakuza gang, but he chose to keep quiet to protect her.

School: Shirokin High School, Class 3-D [1] Family: Lives with his single mother (his mother works hard to support his education, so Uchi loves and cares for his mother very much, though he doesn't often show it.) Distinctive Appearance: Blonde curly hair, 2000s delinquent style, has a tough-guy personality and always ready to fight.⚡ Personality and Behavior: Outwardly Hot-headed but Inwardly a Good Person: Uchi often looks like a troublemaker who likes to get into fights [1]. He is hot-headed and impulsive, but in reality, he is not a bully and has his own morals. Loyal and Grateful: Uchi values ​​his "friends" and "mother" above all else. He is willing to get hurt or sacrifice himself to protect the people he loves. In many episodes, he faces many problems but survives thanks to the help of Yankumi and his friends. Second only to Shin in leadership: Among his five friends (Shin, Uchi, Kuma, Minami, Noda) [1], if Shin is absent or doesn't express an opinion, Uchi is usually the one to lead the team in making decisions or taking action. Tsundere (doesn't say what he means): He says he doesn't care, doesn't mind, or acts annoyed at Yankumi (his homeroom teacher), but in the end, he is the one who respects and obeys Yankumi the most because Yankumi is the first teacher who sees his true nature and is ready to protect him.

Yamaguchi Kumiko, or "Yankumi" as her students call her, played by Nakama Yukie, is the main character of the series Gokusen (Yakuza Teacher). She's a positive-minded homeroom teacher who uses kindness and compassion to win over the hearts of the delinquent students in class 3-D. 📌 Her Harsh Background: Occupation: Math teacher (but actually more skilled in physical education and martial arts). National Secret: She is the 4th generation heir of the Oedo Clan, a powerful yakuza gang in Japan. Having lost her parents at a young age, she grew up under the care of her grandfather, Ryuichiro Kuroda, the 3rd generation leader, and his subordinates. Ultimate Dream: Despite being the heir to a powerful gang, she refuses to inherit the gang because her only dream since childhood has been to be a teacher. ⚡ Personality and Strengths: Outwardly nerdy, but a fighter at heart: She usually wears her hair in pigtails and thick glasses. She always wears a red/pink tracksuit, appearing as a clumsy, goofy, and overly optimistic teacher. But when she "takes off her glasses and lets her hair down," it's a warning sign that her tough, adventurous side has awakened. She loves and protects her students with her life: her motto is "My students, I will protect them." She never abandons the delinquents that society labels as trash and is ready to single-handedly fight dozens or hundreds of gangsters to save her students, with the strict condition that the school never finds out her Yakuza secret. Virtuous and loves to preach: Every time after defeating an enemy, Yankumi always stands and preaches about "being a man," "friendship," and "family" to both the criminals and the students, in a stern yet warm and sensitive voice. Sensitive about love (but incredibly clueless): Yankumi secretly likes her dream guy (like Officer Shinohara in Season 1) and often daydreams, but she's incredibly naive about the love around her, especially unaware that Sawada Shin secretly has feelings for her and is watching over her from afar.
