MIYABI AIZAWA
MA
The elegant, fiercely bitter, and terrifyingly cold shadow leader of Class 3-4's anti-teacher crusade. Driven by a deep, absolute hatred for educators due to a horrific past institutional betrayal that shattered her trust, Miyabi is the operational mastermind who keeps the class unified in their sabotage. While others like Kikuchi and Murai eventually cave to Onizuka’s raw sincerity, Miyabi digs her heels in, escalating her tactics from petty classroom pranks to framing Onizuka for kidnapping and ruinous extortion. She is the definitive human wall Onizuka has to break down to save the class.

Open page →Lessons 42-43 · Saitou's Stabbing · The Truth Behind Class 3-4
The anime finale finally exposes why Miyabi never stopped fighting teachers. Her former teacher Noboru Saitou had an improper relationship with Miyabi's friend Miyuki Yokoyama. Pressure from the education establishment pushed Saitou to deny the relationship, and Miyuki later died by suicide. When Saitou is found stabbed, suspicion falls on Miyabi.
The Breakdown
Onizuka refuses to let the institution bury another student to protect itself. He takes responsibility for the stabbing accusation long enough to force the hidden history into the open. Miyabi finally sees an adult choose the student over his own reputation, which is the exact choice the adults in her past failed to make.
Onizuka vs. The ¥8 Million Field Trip Crisis
Open →Lessons 29-33 · Stolen Money · Fujiyoshi · Okinawa or Bust
Miyabi's most effective late-series attack starts with the money collected for the third-year class trip. The cash disappears after Kouji Fujiyoshi is entrusted with it, and a setup leaves Onizuka looking like the adult who squandered the fund.
The Breakdown
Onizuka promises the students an Okinawa trip anyway and spends Episodes 29 through 33 trying to replace roughly ¥8 million while Miyabi keeps sabotaging every escape route. Fujiyoshi's despair, Urumi's discovery of the setup, Saejima's dubious help and Onizuka's refusal to retreat turn a money scandal into another test of whether Class 3-4 will believe the institution's version of him or what they have actually seen.
HOLY FOREST & CLASS 3-4 //
Open page →Saitou · Miyuki Yokoyama · The Betrayal Behind the Revolt
Class 3-4's war on teachers is not random delinquency. In the anime, the break traces back to former teacher Noboru Saitou and Miyabi's friend Miyuki Yokoyama. Saitou had an improper relationship with Miyuki. When it was exposed, pressure from the education establishment pushed him to deny it, and Miyuki later died by suicide.
Why it matters
Miyabi watched the adults close ranks around the institution instead of the student. The class turned that betrayal into a campaign against every homeroom teacher who came after Saitou. Episodes 42 and 43 finally reveal the wound that Onizuka has been fighting since he entered Class 3-4.

Urumi Kanzaki is not part of this command structure. Miyabi brings her back in Episode 16 hoping the genius will destroy Onizuka, but Urumi becomes her own force and eventually one of Onizuka's strongest allies.

A sweet, clumsy student with low self-esteem who was constantly belittled by Miyabi. Onizuka recognized her natural beauty and gentle warmth, entering her into a national idol competition to build her self-confidence and launch her career.
