Other Characters

Nanako Mizuki (水樹 ななこ, Mizuki Nanako?)

• Voiced by: Yuko Miyamura (Japanese), Cindy Robinson (English)
• Japanese live-action actor: Kirari, Tanuichi Risa (2012-Remake)

Nanako Mizuki is a student at the Musashino Public High School, in a class of troublemakers that Eikichi Onizuka is assigned to for teacher training. Initially, she agrees to set Onizuka up, seducing him into taking her back to his apartment, where she undresses for him. At that moment, some of the boys from the class take a picture of Onizuka and Nanako together, threatening to release it to the media, if he doesn't pay a large sum of money. However, Onizuka is able to "persuade" the boys to keep quiet, with a little help from his old biker gang.

Despite the set-up, Onizuka agrees to take Nanako back to his apartment, after she insinuates he might be able to sleep with her. However, this is just a ruse, when she explains that due to her parents having no time for family bonding anymore, because of their tight jobs, Onizuka's small apartment reminds her of the time when her family used to live in these conditions and were much closer. This moment sparked Onizuka's revelation of actively resisting the urge to sleep with his female students.

Onizuka solves her problem by walking into Nanako's home with a sledgehammer, bashing a hole in the wall separating her parents' bedrooms, assuring her the wall will not act as a barrier between Nanako and her parents. Her parents have the physical hole filled, but she realizes that time and her efforts can heal the spiritual rift in their relationship. To show her appreciation, she briefly, and without panties, flashes for Onizuka, promising that he'll be the one to take her virginity. She does not reappear in the manga or anime, after this.

In the live-action, Nanako studies at Holy Forest, so as to keep her character. Fortunately, her story remains the same as her manga and anime counterparts. Here, she affectionately calls Onizuka, "Onichi", and fills in the group role of Kunio Murai for Kōji Fujiyoshi and Tadaaki Kusano.

Hidero Ohsawa (大沢 秀郎, Ōsawa Hiderō?)

• Voiced by: Shinichiro Miki (Japanese), Ron Allen (English)

The first teacher Eikichi Onizuka meets at Musashino Public High School during training, Hidero Ohsawa has a reputation for sleeping with his female students and convinces Onizuka that teaching high school is the way to lose one's virginity. He states the prospect of having a beautiful, 16 year-old wife, even at the age of 40, is irresistible to the ears of the 22 year-old Onizuka. Upon learning that Nanako Mizuki has been staying over at Onizuka's apartment, with no action going on, Ohsawa insists that he forces himself on her, and videotape it to keep her quiet about it (ensuring that Onizuka's "merchandise" won't go to waste). However, Onizuka does not follow-up with Ohsawa's advice.

Ohsawa is not seen, after Onizuka finishes his training, but it is revealed that he was caught having an affair with a student, and left for another training session, away from Musashino High.

Makoto Fuyutsuki (冬月 まこと, Fuyutsuki Makoto?)

Makoto Fuyutsuki is Azusa Fuyutsuki's 17 year-old sister. She is in the detective club in her high school, which helps her and Eikichi Onizuka a great deal, when they are trying to find a missing Azusa, who left a cryptic fax message to her parents and sister. Makoto is also adept in judo, carrying a white belt. Surprisingly, she is a big fan of hentai pro-wrestling.

Hidemi Ohta (太田 秀美, Ōta Hidemi?)

• Voiced by: Tomoe Hanba (Japanese), Debra Cunningham (English)

Hidemi Ohta is the spoiled daughter of a Tokyo legislator and president of a concerned parents' group (not the Parent-Teacher Association group). Suguru Teshigawara is her math tutor, and through him, develops a dominatrix-type of persona, having him lick her feet. She tries to get Eikichi Onizuka to do the same, on threat of having him fired from Holy Forest from her legislator father, but is summarily kidnapped by the yakuza, who wants to use her as blackmail against her father. However, Onizuka follows the kidnappers to their hideout, where he engages them, rescues Hidemi and hurries back to finish his examinations, even though he is heavily wounded during the fight.

Hidemi's parents eventually arrive at Holy Forest, and though it seems they are there to chastise Onizuka's presence as a schoolteacher there, they see in him a "true educator", and are moved to tears for rescuing their daughter. Mr. Ohta gives Onizuka his full support, just as the results of Onizuka's examinations are being printed.

Yoshiko Uchiyamada (内山 田好子, Uchiyamada Yoshiko?)

• Voiced by: Atsuko Bungo (Japanese), Kate Davis (English)
• Japanese live-action actor: Erika Mabuchi, Komatsu Mizuki (2012-Remake)

The daughter of Hiroshi Uchiyamada, Yoshiko Uchiyamada is into designer handbags, ganguro fashion, and according to her father, "single handedly keeps the tanning salon industry alive". Although Eikichi Onizuka abstained from any sexual relations with students, he and Yoshiko meet at a karaoke place and strike a quick friendship, the connotations of which severely anger her father. The "gap" between Yoshiko and her father is already large to begin with, as she openly disdains him for his deluded imaginings and not living up to her own material expectations.

It is implied in the manga that she may not be Hiroshi Uchiyamada's biological daughter, but the meat delivery man's, though this could be argued as another one of Uchiyamada's paranoid delusions.

Julia Murai (村井 樹里亜, Murai Juria?)

• Voiced by: Megumi Ogata (Japanese), Cindy Robinson (English)
• Japanese live-action actor: Rikako Murakami, Yoshida Yo (2012-Remake)

Kunio Murai's attractive mother, 27 year-old Julia Murai carried Kunio at the age of thirteen, and chose to run away to be able to keep him, when her parents disowned her and Kunio's father abandoned her. Julia works as a crane operator at a local construction yard, and is known to wearing skimpy outfits and no bra. On occasion she would also model bridal gowns for her boss (which led her son to think she will be married to a man who looks like Dr. Elefun). Although Eikichi Onizuka swore off relations with female students, their mothers are still available, thus, he attempts to woo her on multiple occasions, even asking her out once.

Kyousuke Masaki (真樹 京介, Masaki Kyōsuke?)

Kyousuke Masaki is Eikichi Onizuka's deceased idol from his bōsōzoku days, and the original owner of his Kawasaki ZII. Although he first appeared in the predecessor to GTO, Shonan Junai Gumi, Kyousuke appears briefly in a vision while Onizuka is in a coma, urging him to go on and become the greatest teacher in Japan.

Heihachi Mishima (三島平八, Mishima Heihachi?)

• Voiced by: Daisuke Gori

Heihachi Mishima is based on the Tekken video game character of the same name. In Great Teacher Onizuka, he makes a cameo as a former detective, now working for his own company, the Mishima Zaibatsu.
