The plot involves Kumiko Yamaguchi, the granddaughter of a Yakuza boss, Kuroda of the Kuroda Ikka. Her parents died when she was at the age of seven, and her grandfather had no other descendants, so Kumiko is next in line to head the family business with the title of Ojou. However, her lifelong dream has been to become a teacher. While her grandfather approves of her choice, others in the family want her to become the next boss.
Kumiko (known by her students as "Yankumi") becomes a teacher at an all-boys private high school. Her class is full of delinquents, but she tries her hardest to teach them not just about academics (her subject is Mathematics), but about lessons of life, much like any "dedicated teacher" story. Though she's forced to keep her family a secret from the public, her Yakuza upbringing gives her the strength and the experience to reach out to her students, while also providing comedic relief.
==Why It Rocks==
- Outstanding main female character. She's incredibly strict and can be a bit of a bitch at times, but she's ultimately likable and truly does care for her students.
- Amazing animation.
- This series proves that you can have an anime series with a main female character that has literally no fanservice in it whatsoever.
- Excellent soundtrack.
- Gokusen is very similar to the Great Teacher Onizuki in many ways. The only surface level differences are the genders of the characters and the fact that the main female character of Gokusen is the daughter of the Yakuza. This would lead people to believe that it's just a ripoff, however, the similarities are only surface level, it does its own thing and is able to stand alone as its own entity.
- Great voice acting in both sub and dub.
- Phenomenal dark comedy. Whenever there isn't action or drama, comedy is what carriers the show. Hell, sometimes the comedy is mixed in with the action, and when that happens, it blends together very well.
- Good pacing.
