Kumiko Yamaguchi

The anime and manga series' main character is Kumiko Yamaguchi. She is hired as a math teacher at Shirokin High Private School. She was placed as the Homeroom Teacher of 2-4, a class filled with gang delinquents. However, no one at school is aware that Kumiko is the heir to the Kuroda clan, a prominent Yakuza clan. She conceals her Yakuza past in order to continue working as a teacher.

Kumiko may not appear to be the best candidate for a teacher because she comes from a Yakuza family. However, placing her in charge of a class full of delinquents is the ideal solution. Kumiko is severe and serious when it comes to instructing her class, despite her delicate appearance. Though most have given up on her class, she remains positive and determined to see that they all graduate from high school.

Kumiko Yamaguchi appears frail, but she is a great fighter. In the first episode, she dodges the Pachinko thrown by her student, but she pretends to be so astonished that she actually did it. Despite a rocky start, she and her students eventually learn to appreciate and like her. Kumiko faced many challenges at first, but she refuses to give up on her dream of being a teacher and on her kids.
