A biker gang leader who made the most unusual of career choices to become a teacher, and that's just because of a high-school student. Motivated by his dream of having a 16-years old wife by the time he's 40. Good at fighting and also a pervert. His stupidity is prevalent, but in the end, all his actions make sense, so far.....

Anyway, in both version, she is still a daughter to a rich parent who likes to blackmail teachers with her cronies (in the drama, her cronies is Taadaki Kusano and Kouji Fujiyoushi).

Description: A paranoid student, who love his mother Juria Murai (a 27-year old hottie) probably too much. And the fact that Onizuka is trying to hit it off with her doesn't help either. Shy around girls, especially the one he admires, but he doesn't even sure about his own feelings. Become an Onizuka-clan member in 4th volume, after an adventure on a bay bridge.

Love interest (drama): None (no appearance).

And always slow in everything she do, either in studies and sports. Don't have a lot of friends, apart from those two who are her friends since primary school. In the end, she gained self-belief with Onizuka's help, and defeated Aizawa in a talent/beauty contest, paving the way to stardom, and also embarassing Miyabi Aizawa in front of the whole class. Obviously, she is a major character in this manga, as she have her own miniseries; GTO- Great Toroko Oppai (literally means the famous big-breast girl), in volume 11 and 12. Onizuka-clan member by 5th volume.

Love interest (manga): Eikichi Onizuka.
Love interest (drama): Yoshito Kikuchi.

Name: Urumi Kanzaki | Drama appearance: No, which is a waste of one of the best characters in manga history. Rika of GTO Drama Special is simply no match when compared to this "devil mermaid princess"

Description: Another major character in GTO and also MY FAVOURITE!!! She is an arrogant blonde (her hair IS NOT COLORED) with an IQ level of over 200. An expert of class/school terrorism, even managed to blackmail Onizuka after a VERY BIG screw-up by him. An event in the primary school make her hate all of her teachers (just like Miyabi Aizawa), adding not only Onizuka, but also Azusa Fuyutsuki, Taadashi Sakurai and Hiroshi Kochiyitani inside her list of victims. She become an Onizuka-clan member after an unique counselling session in the 8th volume, thus turning her friendship with Miyabi Aizawa into a very bitter rivalry. And I really meant it when I say bitter.

Love interest (manga): Eikichi Onizuka.
Love interest (drama): None.

Name: Mayu Wakui | Drama appearance: No.

Description: Just like Urumi Kanzaki, he's good at terrorising the school and the class. Grandchildren of Ryoko Sakurai, thus the VIP treatment he gets. Sport a very good look. Good at fighting too and a leader of a gang-biker group. Seems to have become a drug addict. Become Onizuka-clan member (much to Miyabi Aizawa annoyance) by 16th volume, after he was defeated by Onizuka in an arm wrestling contest. He then went on to become a singer, under the same management as Tomoko Nomura.

Love interest: None in both versions.

Name: Yuki Miyamori | Drama appearance: No.

Description: A 3rd Year 4th class student who never comes to school for more than 2 years. He is the son of a yakuza group leader and become an introvert boy because his friends that he trusted deserted him. Yoshikawa and Onizuka managed to talk to him to change his lifestyle, thus saving Onizuka's salary in the process. Onizuka-clan member at 20th volume.

Love interest: None in both versions.

Name: Shiro Shibuya | Drama appearance: No.

Description: One of the 2 new students that entered the 4th class at the start of the second semester. At first, he is seen as a weak boy who always been bullied, and Onizuka even risked his life to save him when he tried to commit suicide. As the story progressed, he is eventually shown to be one of Headmaster Daimon's henchmen too. And it seems that their relationship is complicated....

Love interest: None in both versions.

Name: Ai Tokiwa | Drama appearance: No.

Description: The 2nd student who entered the 4th class. One of the Headmaster Daimon's followers. Good at fighting, she even managed to floor Kikuchi after he found out that she had some sinister scheme. Even that, she is defeated in an instant by Onizuka in front of all the students in an emergency assembly, and when she wanted to take revenge, Kikuchi exacted his own revenge on her with the help of Mayu Wakui. Onizuka-clan member by 22nd volume.

Love interest (manga): Yoshito Kikuchi.
Love interest (drama): None.

GROUP: THE FEMALE MAGIC USERS CLUB (Think of the TV show "Charmed" here)

Name (from top to bottom): Ruruka Hikita, Madoka (the leader) and Miko | Drama appearance: No.

Description: These 3 are also students of the 4th class, and they are attracted to things supernatural. They gained their knowledge from cult comics, books and magazines, and get their daily fortune reading from fortune-telling slot-machines. But I must say, Ruruka Hikita is kinda cute, probably the most beautiful in GTO because of her mature looks. All of them are the main characters of a sub-plot in volume 8-9, started when Ruruka Hikita dreams that if she make a collision with a man, that man will become the love of her life. At the school, when she run to touch Itou-kun that she admires, she collides instead with the butt-scratching Onizuka. From there, all hell break loose, as one of the funniest sub-plot (IMHO) in GTO, developed. I even think, if there's someone or a group that could oust Onizuka from the school, it will be them. Even Kanzaki is nowhere as violent as they are....

Hikita's love interest (manga only): Eikichi Onizuka.


Name (clockwise from top):

  1. Mokuma Shiroi as Zeta Gundam.
  2. Haruo Tokida as Turn-A-Gundam.
  3. Urumi Kanzaki as Salya Mass. ^_^
  4. Gunjin Mishima as Gundam RX-78-2.

Drama appearance: No.

Description: All three of them (except Kanzaki) are fans of Gundam, and like to cosplay them. In the Okinawa field trip, Onizuka intentionally put Urumi Kanzaki with them in a room, giving her hell as she don't have a clue on what they're saying, even that she have IQ over 200 and mastered 5 languages. And in the test of bravery game (that Onizuka use to matchmake both Anko Uehara and Noboru Yoshikawa), again Kanzaki and the 3 of them have to team up as they are facing the terror of their lives when all the 'ghosts' are descending on's just too funny. For the side note, they worshipped Kanzaki as she have blonde hair like Salya Mass, another character from Gundam.

Love interest: None in both versions.

Student from other classes (2nd class to be particular).
