"I made a choice, to get my revenge on everyone! I'll let everyone experience the same hell as I did!"

"Why do they have to go this far? As I was almost killed, I realized that... they don't really have a reason. It just so happens I was caught in their web. A web known as malice. Whether you put up with it or put up a fight, it makes no difference. In the end, you get killed. If you don't like that... risk you life... and retaliate."
— Fujisawa Ayana

Fukushuu Kyoushitsu ("Revenge Classroom") is a manga by Yamazaki Karazu, with art by Kaname Ryu.

The manga follows Fujisawa Ayana, a girl who gets bullied and abused on a daily base by her classmates. After surviving a murder attempt by an unknown classmate, she realizes that it's kill or be killed, so she starts a plot to take revenge on everyone in her class.


  • Aborted Arc: In-universe, Ayana throws some of her revenge plans away after situations change, such as the splitting up of the class between schools or the increased focus on Ren.
  • Abusive Parents: Both Ayana and Yuuko have a set, but Yuuko's are far worse. While Ayana's parents are content to basically consider her a failure and a shame, Yuuko's parents, once Yuuko's clubbing is exposed, lock her up in her room and keep her there, studying, until they forgive her.

  • Accomplice by Inaction: Ayana will take revenge on everyone in her class, even those who did nothing against her, because they did not help her either.
  • Accuser of the Brethren: It's too late to apologize to Ayana, it does not matter your intentions or regrets.
  • All the Other Reindeer:
    • Ayana is heavily bullied in school, she gets help of Shouta and Ai by convincing them that, when she is gone, they'll seek other targets and they are the most likely ones.
    • Apparently, the entire class, once disbanded has been singled out by the students of the schools they are sent to, out of fear they are cursed.
  • Ax-Crazy: Ayana and Ren, particularly, but Yamase seem to have traits of it.
  • Beware the Nice Ones: Yamase can get pretty dangerous when mad. He also turns out to be the one that set up everything in the classroom for Mari and Ayana's confront. Just For the Lulz.

  • Beware the Quiet Ones: Miho Tsukamoto seems to be up to something weird, to the point where even Ren does not mess with her.
  • Big Good: Miho turns out to be this. She had been secretly trying to protect Ayana and put an end on her revenge that would also make Mari pay for her crimes. She was also the one to figure out and make plans against the real Big Bad, Yuuya
  • Black-and-Grey Morality: The people who are not outright evil jerkasses, are at least welcoming of the use of violence.
  • Bloodier and Gorier: Some revenges are bloody torture and accidents, some are not. Particularly, Kawamoto (being throw in a pit with a board pinned with nails) compared to Igarashi (threatened by muggers).
  • Bookends: Invoked by Mari. She kidnaps Miho and calls Ayana to come find her in the 3-3 classroom where their revenge battle started, as she thinks it's fitting that it would also end there.
  • Bookworm: Miho, who quotes Osamu Dazai and can put even Ren in his place.
  • Bully Brutality: Ayana's bullying is truly horrendous, up to and including multiple counts of rape and even being thrown under a car, with the bullies expressing actual disappointment that she survived. It's little wonder that she decides to go on her Roaring Rampage of Revenge.
  • Central Theme: The Cycle of Revenge is endless, continuous and fruitless. Nothing comes out of revenge aside from violence, from revenge, you will not find happiness, satisfaction or justice, just possibly some catharsis before someone else tries to get revenge on you.
  • Corrupt the Cutie: Ai starts to go completely on board with Ayana's ideas no matter how bloody, due to slowly accept her ideals.
  • Cycle of Revenge: Ayana was a target of violent bullying from Mari, as she was trying to get revenge from the suicide of her father, whose death she blames on Ayana's father. The violent bullying ultimately leads Ayana to unleash revenge on everyone. After the "Revenge Classroom" Case is made public, several stories of violence between minors due to bullying and revenge sprout nationwide as a surge of crime between minors happen.
  • Despair Event Horizon: Yuuko and Mei's death, to Ayana. After that, she is even more roary rampagy and revengy than before.
  • The Dog Bites Back: Ayana, Ai and Shouta do that.
  • Downer Ending: Much of the class is dead, and everyone who survived experienced a lot of mental or physical trauma (if not both). Ayana ends the series in a coma from falling from the 4th story of the school. And Yamase, who was ultimately the instigator of the entire plot, gets away scot free, as apparently Ren is unable to bring himself to kill him, even knowing everything he's done. And news of the events has lead to a chain of copycat cases of students violently attacking each other in revenge for bullying across Japan.
  • Driven to Suicide:
    • Yuuko, after spending too much time in her parents' punishment.
    • It's implied in one chapter that Ayana intends to do this after she has gotten revenge on all her classmates. Though at the end she decides that a better fate would be to live with her crimes the rest of her life than simply die.
  • Enemies List: All volumes of the manga have a picture of each member of the class. Those that Ayana already took revenge appear with a mark on their photos.
  • Exact Words: Ayana promises Yuuki that his friend won't freeze to death, Ayana then burns down the place they were locked inside.
  • Final Boss: Ren is compared to one, being the most powerful member of the class. In the end though, Ai manages to catch him off guard and incapacitate him right before the finale, making it seem like it is Mari and her gang who will become the final obstacle... only for Shouta to show up with a chainsaw.
  • Foreshadowing: In hindsight, Miho's quotes of Ningen Shikkaku hints that she despises herself for failing to protect Ayana and plans to die.
  • He Who Fights Monsters: Ayana realizes she is causing just as much harm as it was caused to her. She doesn't care at all, she is completely ok with it and is ambiguously the point of her revenge.
  • The Hunter Becomes the Hunted: To everyone who bullied Ayana.
  • I've Come Too Far: After Emi saves Ayana from some bullies and shows her that even though Yuuko has been ignoring her, she regrets it and wants to make it up to Ayana, it seems Ayana is truly considering giving up her revenge, at least on them. However her already commited plans causes Yuuko and her parents think Emi sold her out. Yuuko kills herself and Emi accidentally falls to her death. Ayana is horrified but decides to continue her revenge plans. However its clear she has lost it since her plans start being rather lethal than just humiliating.
  • Kissing Cousins: The only woman that Ayana's father ever truly loved was his Ill Girl of a cousin who turned out to be Yuuya's mother. The family, however, exiled her and made Ayana's father marry Ayane's mother into a Loveless Arragned Marriage. He's hated both women ever since. Yuuya and Ayana are if fact half-sibilings.
  • Lesser of Two Evils: How Kawamoto sees Ayana: he agrees to do everything she orders because she has a recording of him raping her, which was against Ren's rules, and facing her revenge is better than facing his wrath.
  • No Good Deed Goes Unpunished: Yuuko tried to help Ayana after the accident, forcing people to stop bullying her. Ayana never knew that, and after a while, realizes that it doesn't matter for her anymore.
    • Ren chooses not to kill Yamase when he has the chance out of some sort of kindness. It turns out that Miho had actually asked Ren to kill Yamase, as she knew that he was the instigator of literally the entire plot, and by leaving him alive, Yamase goes on to free Shouta who had gone insane from his imprisonment. Through Yamase's manipulation, Shouta takes a chainsaw and kills one student, severely maims another, and causes Ayana to jump out of a window multiple stories up, putting her in a coma that she does not come out of before the end of the story. If Ren had killed Yamase like he had others without issue, the story may not have had a happy ending, but at least a happier ending.
  • Pay Evil unto Evil: Ayana's ideals.
  • Rape and Revenge: So far, a total of 4 men have already raped Ayana, 3 of them did that together, and Ren considers her his toy.
  • Revenge: The whole base of the plot, it's in the title.
  • Revenge Before Reason: Downplayed in Ayana's case: she realizes her revenge will forever haunt and keep her away from a normal life, but doesn't believe that there's anything else for her and that she has gone too far.
  • Roaring Rampage of Revenge: The very base of the manga is Ayana taking revenge on her class.
  • Sanity Slippage:
    • Ayana after Yuuko's suicide.
    • Ai does this later on, as Ayana's beliefs worm their way into her head.
  • Shrinking Violet: Both Ayana and Ai, for a while.
  • Was It Really Worth It?: Part of Ayana's Despair Event Horizon, she ultimately decides that it was.
  • Wild Card: Miho is strange, she is seemingly doing her own thing, which surprisingly ends up helping Ayana, but that was completely on her purpose... possibly...
  • Woobie, Destroyer of Worlds: Ayana has been bullied, abused verbally, emotionally and sexually, gang-raped, threatened and ultimately, someone tried to kill her by pushing her in front of a car. She is willing to kill everybody in her class, but you see where it comes from.
  • White Sheep: Some of the characters from class 3 are genuinely nice people, such as Yamase, Ai, Kitaura and Emi. They are, nonetheless, on Ayana's list.
  • Villainous BSoD: Ayana has one after Yuuko's suicide and Mei's death, after which, it becomes her Despair Event Horizon and goes full blown-out Ax-Crazy.
  • Yandere: Ken seems to be this for Ayana, as he has already killed Daisuke, one of her previous rapists, and Shouta, who Ayana kept around to do the dirty work.
  • You Have Outlived Your Usefulness: Shouta's ultimate fate. After killing Ochi, Ayana realizes that it's too much of a liability to keep them around, so she locks him in the basement of the abandoned apartment complex, telling him she will take him out of there after everything ended, that is, if he's still alive by then.

How well does it match the trope?
