List of Characters

Urumi Kanzaki (神崎 麗美 Kanzaki Urumi) is the star pupil of the Holy Forest Academy and a student of the notorious Class 3-4. She is a genius with an IQ of over 200, and an enfant prodige which possesses large knowledge of philosophy, mathematics, physics, engineering, chemistry, biology, literature, the arts and many more. She also speaks five languages, from Japanese to Chinese through English and French. Being extremely cunning and strategic and developing her own form of existential thought during the series, she is indisputably "the Mind" of the group of G.T.O.

Her date of birth is November 9th, 1984.


Urumi is a beautiful young girl with a very pretty, delicate face and refined, elegant carriage. She has blonde hair, fair skin and different colored eyes – the right is blue, while the left is castaneous – since she has the complete form of heterochromia iridum. She has long, slender legs, curved hips, proportionate but bigger than average breasts and a slim figure.

She is commonly seen dressed in a yellow sweater-vest, a white button-down shirt (worn under the sweater-vest), a blue miniskirt, white loose-fitting socks and black laceless shoes. Her outfit throughout the series is her summer uniform. Her initial appearance while she poses as being 19 years old despite her real age is 15, she wears a blue sleeveless denim dress.


Urumi may seem like a child that is happy, but she is a mischievous and spoiled girl who is considered as a special child prodigy due to her IQ which is higher than 200, who is also regarded as the star of the school and therefore has the full protection of the vice-principal. Being very smart, her mom wants her to go to MIT and sometimes looks like a miss know-it-all type of girl. She also plays the piano and is able to speak up to five different languages. However, she seems to prefer using French whenever she is seriously annoyed. Was there need Urumi has proven that she will readily set up bombs and even take away her own life, making her a bit unstable, suffering actually from a deep lack of love and boredom.

Kanzaki teasing Onizuka

Urumi is initially depicted as a sociopath. She presents herself as a cheerful, energetic child prodigy, but seems to be ruthless on the inside and thus sees no problem with manipulating or hurting others when she needs to, by all means necessary, including physical violence, schemes or phony (but convincing) crying acts as well as her sex appeal. Even if she looks rather cool or charming, she is bossy and might be rude. Therefore, it is not rare to see her jaded, irritated, when she does not like or understand something. At first this is a mystery, as noted by her classmate Murai, who said that she was always like that for as long as he has known her. Her classmate, Kikuchi, noted that she has a troubled history, and warned Onizuka not to take her lightly, as she can be very vindictive behind the appearance. Both of them seem to share the leadership of the group, but Urumi had actually not attended school for quite some time and did not appear until recently. Miyabi had asked her to return to drive Onizuka out of the school. With Tomoko, she is a childhood friend of Miyabi, but will not hesitate to frame her and her clique for revenge.

Being quite playful and taunting, Urumi's methods of classroom terrorism are the following: She likes to ask her teachers extremely difficult questions, knowing that they are not able to answer correctly. She does this because she likes making them look foolish in front of the class. Also, she uses her knowledge of chemistry to make all kinds of explosives. When she does not feel like doing this, she simply uses her wealth to purchase dynamite. Both techniques she uses when she is angry. It should also be noted that she likes to flirt with her male teachers, convince them that she is into bondage and then frame them, making it look like they were trying to rape her, or  tease her private tutors and making them do unsolvable problems to get her panties. Ironically, Urumi herself is not immune to this, shown by how utterly helpless and lost she herself felt when forced to room with the Gundam Otaku, whose own innate fandom knowledge of which Urumi had none of left her feeling as Ignorant as she'd left her teachers feeling previously.

Progressively, Urumi starts to genuinely like Onizuka. Despite the fact that he is not wealthy or sophisticated like her, she likes him because she realizes that he would do anything for his students. However, she tests to see if this is an act by going out to dinner with him and then causing as much mischief as she can. By the end of it, Urumi is standing on the ledge of a tall building and explaining to Onizuka that sometimes she considers throwing her life away and committing suicide. Onizuka cheers her up but accidentally bumps into her and causes her to fall. Urumi pretends to be dead and allows Onizuka to almost bury her before scaring him and then revealing that she is just fine. Being a natural manipulator, Urumi blackmails Onizuka, forcing him to become her "magical genie of the lamp" in exchange for keeping quiet about the incident. Urumi then proceeds to finally enjoy school, using Onizuka to explore Tokyo and eat at expensive restaurants.

Urumi having fun by tricking Onizuka to be able to cancel the curse if he covers himself by spells (episode 23)

After encountering her 1st Grade teacher, Ms. Fujimori , while having fun with Onizuka, it is revealed why Urumi hates teachers so much. When she was in first grade, Urumi was actually a very sweet girl. However, she was lonely because her classmates thought she was a freak for being so smart for her age. Ms. Fujimori had taken an interest in her and became very close with her. Urumi would come over to her apartment each afternoon and Ms. Fujimori would tutor her in college level work. Urumi saw her as a surrogate mother, seeing as her actual mother was always busy at work. Urumi later opened up to Ms. Fujimori and told her that she is actually a test tube child born from her mother's egg and the sperm of a brilliant American scientist. However, this friendship was not to last. Eventually, Ms. Fujimori grew jealous of Urumi's intellect and revealed her secret to the class because Urumi corrected her during a history lesson. As a result, Urumi planted a bomb in the elementary building and blew it up. It was later rebuilt and re-opened.

After being taught a "lesson" by Onizuka, Urumi changes for the better. She remains friendly but stops faking her feelings and becomes more honest. Also, she stops terrorizing her teachers. Finally, she switches loyalty from Miyabi to Onizuka. Now having feelings for him, Urumi becomes a tsundere. She is kind and affectionate towards him but will ruthlessly beat him whenever she sees him do foolish things or flirting with other girls. Though it should be noted that Urumi has had some doubts as to whether her feelings for Onizuka will go anywhere, seeing as he is an adult and she is a minor as well as the fact that he is a pervert and just likes to flirt with cute girls. At one point, believing he was going to die, Urumi had wanted to commit suicide to go with him.

However it should be noted that Urumi cites to Onizuka how much she will develop and the fact she will not be a minor forever.


Urumi jealously hides the secret that involves her origins; the very same secret partly the root of her dangerous behavior. When she was very young she was revealed the fact that she is the product of her mother been fertilized by a scientist test-tube sperm, revealing the fact she has no actual father on whom she can rely. (She was actually born from IVF (in-vitro fertilization))

Already in elementary school Urumi's genius was starting to appear, this was shown by the fact that she found lessons extremely boring due to the fact that the level of difficulty was far too low due to her special capacities. Eventually her teacher, Ms. Fujimori, noticed this and decided to invite Urumi to her house every day after school so that she would be able to teach subjects whose level would have satisfied Urumi's vast intellect. However, Urumi was learning excessively fast even for Ms. Fujimori and soon she reached college level subjects at the young age. Unfortunately, their level of difficulty was so high that Ms. Fujimori ultimately found out that she was unable of helping Urumi any further, leading her to understand that Urumi had outgrown her intellect. Following these facts Ms. Fujimori decided to stop seeing Urumi after school, as she couldn't bare the fact that she was not able to answer her questions, until she finally snapped. While Urumi was trying to correct a mistake that her beloved teacher committed during a lesson in school, Ms. Fujimori snapped and revealed to the whole class about Urumi's secret. Since then Urumi stopped smiling or faked them (as kikuchii noted) having lost her trust in teachers.

However, when she met Eikichi Onizuka, he made her realize and admit to herself that the reason why she started hating Ms. Fujimori and all of the teachers was due to the fact that when she "lost" her primary school teacher she even lost her only loving place she could go back to as well as her surrogate mother, Ms. Fujimori. In the beginning of Episode 29 through Episode 32, she was the only person to confront Miyabi Aizawa twice when she berates her for making a mistrust towards adults including Onizuka whom she framed him for the money embezzlement in order to get him fired. Urumi was also behind to cause a kidnap for ransom towards Miyabi and her friends in Episode 33 after she was threatened to be told about her father by her. She even countered Miyabi's reaction by calling the police by threatening her about the money she had embezzled to frame Onizuka and for making her angry. Her dangerous plan stops when Kikuchi manage to call Onizuka to rescue them.


Eikichi Onizuka

Onizuka is Urumi's homeroom teacher who first starts manipulating him and using him as a "slave" due to her game, but she will later find in Onizuka a funny hobby to spend time with. She later will become one of his biggest allies and, thanks to her intelligence, will know how to help him in various situations. Also, she has developed a crush on him.

Miyabi Aizawa

Back in primary school, Urumi and Miyabi used to be very close friends. Until the outcome with Onizuka, Urumi sided with him. Miyabi in many ways tried to stop Onizuka, and to make other teachers hate on him, so he can be kicked out of the school as a teacher.

In the anime when Miyabi threatens Urumi because of her secret, she angrily wants to teach her a lesson by setting them up with her friends by sending a Yakuza to tie them up and make a kidnap for ransom inside the hotel that they need to celebrate for framing their teacher. Her actions are soon halted by Onizuka when he rescues Miyabi and her friends by taking the Yakuza down which Kikuchi had contacted him to save them.

In the manga she insults Miyabi at a carnival, leading her to reveal Urumi's secret to the entire school. Urumi retaliates by posting a website where it claims to post pictures of Miyabi in the bathroom taken with a hidden camera. Miyabi attempts to commit suicide by overdosing on sleeping pills, but survives. The website is revealed to be a ruse.

It's later revealed that despite Urumi's hate for Miyabi, she still treats her as a friend and still worries about her. When Onizuka was dying, Urumi attempted to commit suicide by cutting her wrist but Miyabi and Azusa stopped her.

Ms. Kanzaki

Having no actual father, all that she's left with is her mother. They both have a very complicated relationship. Urumi's mother is a wealthy stock broker. She is always busy and for as long as Urumi can remember she has never really looked after her, always having a nanny to see to her needs. Now that Urumi is older, she spends most of her time at home by herself, as her mother never has time to spend with her. At first glance, it seems as though the only reason Urumi's mother had her was so that Urumi could go to a good university, get a high-paying job and be able to care for her when she is elderly. However, deep down, she really cares for Urumi, having become a stock broker in the first place in order to be able to provide for her.

Ms. Fujimori

Ms. Fujimori was Urumi's Head Teacher when Urumi was in the 5th grade. She was also the first teacher to make Urumi feel the love of a parent. She taught Urumi subjects that were above Urumi's grade level. At first Ms. Fujimori was able to teach with ease the subject being taught to Urumi not until it came to a time that Urumi surpassed the level she could teach. Due to the fact that Ms. Fujimori had a complex that she can't say "I dont know" to a student's answer, she soon developed an ire to Urumi's intelligence that made her reveal Urumi's secret to her class. Upon that event, Urumi started her Classroom Terrorism and hatred toward teachers.


  • "So far from sky to earth, so wide between past and now, a body of five feet can't understand how vast is the universe, how "greatness" lies within Horatio's philosophy, the omniscient truth of everything is nothing but one word, it is "uncomprehensible". The bitterness inside myself is more unbearable than death itself. My heart is filled with peace and serenity, as I stand atop on that rock, that's when I know, the greatest despair is exactly the greatest happiness."

This poem is a reference to the poem "Thoughts on the precipice" written by a Japanese student named Misao Fujimura before committing suicide.

  • "It's not his fault. He is a teacher... technically."
  • "Let go of me! If he goes, I go!"


  • The name Urumi consists of the terms (麗) ("uru" in her name, "rei" in others) which means both "shining, resplendent" and "lovely", and (美) (mi), the Japanese for "beautiful". The general meaning of her name is then "Shining Beauty".
  • Her surname, Kanzaki, consists of (神) ("kan" in her case, which is "kami" generally), "deity", "spirit", and (崎) (saki/zaki), which means "cape","small peninsula". Urumi's last name can then be translated as "Divinity of the Cape".


  • Gundam Otaku are the only people that Urumi despises who have not caused any harm to her. This mainly stems from the fact their encyclopedic knowledge of Gundam, a fandom Urumi has no experience with, makes her feel stupid. Ironically the exact same feeling she herself made her past teachers experience.
  • Urumi causes pranks and gets away with it regardless, except for Eikichi Onizuka...sometimes.
    • Once she gets mad, she will leave nothing but a trail of tears for the victims.
  • Urumi's character design is the same as Saya Minazuki from Shonan Junai Gumi.
  • She volunteered to take the legal system exam at the end of the school year.[1]
