Juujika no Rokunin is the debut manga of Nakatake Shiryuu. I genuinely think it is a severely underrated revenge driven series. The art style is raw and powerful, which fits the tone of the story perfectly. It feels intense, emotional, and unfiltered.
However, the manga is extremely graphic. It contains repeated depictions of death, drugs, sex, torture, and murder. Because of how disturbing it can be, many readers find it too uncomfortable or disgusting to continue. I believe this is one of the reasons it never became widely popular.
The series began in March 2020 and remained consistent until it concluded in December 2025 with 233 chapters.
Content Warning: This manga contains sensitive topics including death, gore, torture, sexual violence, self harm, animal abuse, and psychological trauma.
Synopsis (Intro)
Juujika no Rokunin follows Shun Uruma, a 12-year-old sixth grader bullied by five classmates: Daichi Kuga, Yuuga Ushiro, Hiro Madoka, Katsumi Senkouji, and Kyou Shigoku.
They call him “Experiment A” and escalate their cruelty from killing his pet cat to orchestrating a car accident that murders his parents and leaves his younger brother in a coma.
After discovering the truth, Shun trains for four years under his grandfather Noboru, a former Kitayama Corps WWII soldier, dedicating his life to revenge.
Full Recap of the Story
After four years of brutal combat and survival training, Shun enrolls at Meiseki High School to hunt down his former tormentors one by one.
First Victim: Katsumi Senkouji
Shun reunites with Katsumi and Daichi. Katsumi pretends to regret the past and tries to gain Shun’s trust. Meanwhile, Shun befriends Chizuru Azuma, who develops feelings for him.
Katsumi kidnaps both Shun and Azuma. Bound and tortured, Shun dislocates his own fingers to escape. He overpowers Katsumi and executes him by peeling his skin open starting from his chest to stomach.
Second Victim: Yuuga Ushiro
Yuuga runs a prostitution ring and keeps his classmate named Karen Sakuraba imprisoned for his sexual abuse. Shun infiltrates Yuuga’s hideout using a fake bomb smoke. He captures Yuuga and tortures him using a medieval device known as the Pear of Anguish. Karen delivers the final blow to Yuuga before taking her own life.
Third Victim: Hiro Madoka
Hiro discovers Shun’s revenge killings and attempts to poison his entire class during the school festival. Kaname Shirakawa, also develops feelings for Shun however she is sexually assaulted by Hiro.
Shun captures Hiro and psychologically destroys him by staging a fake betrayal involving Kyou. Hiro is executed using the torture rack.
Fourth Victim: Daichi Kuga
Daichi, now a violent judo athlete and serial abuser, anticipates Shun coming after him. Shun kidnaps Daichi’s girlfriend Anna and challenges him to a judo fight. After defeating him, Shun drops Daichi into a boiling barrel filled with live mantis shrimp that tear into his flesh.
Anna escapes and tires to rescue Daichi but is sexually assaulted and murdered by him in delusion. Shun finishes Daichi by crushing his skull with a concrete block.
A police officer, Zenichi Anzai, catches Shun. Shun kills him, refusing to stop his killing frenzy until he has finished Kyou.
Kyou’s Revolutionary Club
Kyou Shigoku is different. Calm, intelligent, and manipulative, he forms a brainwashing cult called the Revolutionary Club. Members include Andou, Sanae Momoki, Nogi, Miguel, and their new recruit Jun Shirakawa (Kaname’s twin brother).
Kyou lures Shun to their abandoned elementary school. There, Shun is forced into a deadly game of rock-paper-scissors where losing means Kakeru, his little brother’s limbs are severed. Jun tries to lose on purpose to save Kakeru, only to learn that every time he lost, Kaname’s limbs were also being cut off behind the scenes. After two losses, Kaname’s corpse is revealed to them.
Shun’s grandfather arrives, kills Miguel, but dies protecting Kakeru. Shortly after, his sacrifice is wasted when Kyou personally stabs Shun’s younger brother. Enraged, Shun kills Nogi and scars Kyou’s face, but Kyou escapes and Shun is later arrested.
Juujika Organization Arc
Five years pass. Shun, now suffering memory loss, works with a vigilante group called Juujika (The Cross) alongside Mimi Kawana, and Dr. Kitami. They accept assassination requests targeting criminals including rapists, scammers, and Revolutionary Club members.
Eventually, Azuma helps Shun regain his memories and resumes his mission to kill Kyou, whose cult has now grown nationwide.
Revolutionary Island Arc
Shun infiltrates a cult training island led by Andou and Kurusu. Shun meets Saki Hanaoka, an aspiring model who falls for Shun. Shun also meets Reo Suzuyama, who is also out for revenge on Kurusu for killing her adoptive sister. Shun is captured and tortured by Andou cutting his flesh with scissors. He is eventually rescued by Kitami, Reo, and Kawana.
Shun kills Andou with his grandfather’s knife while Kurusu is executed by Reo by snapping his neck.
King of Moo Moo Street Arc (Filler)
Juujika continues taking vigilante assassination requests. A criminal known as the King of Moo Moo Street kidnaps a girl named Rikka and holds several other girls captive in his apartment. He physically abuses them and forces them to behave like dogs.
Rikka contacts Juujika for help. In response, they eliminate the King by infecting him with parasitic worms known as Sparganum proliferum, leading to his death.
Mount Notomi Arc
Jun Shirakawa contacts Shun and claims he wants to betray the Revolutionary Club to avenge his sister Kaname. In reality, Jun still blames Shun for her death.
The cult is revealed to be surgically altering women to resemble Kaname through forced plastic surgery experiments.
Jun kidnaps two police officers Mizuki Anzai (wife of Zenichi), Oota, and Azuma to lure Shun into a trap at Mount Notomi. Jun is able to corner Shun but loses his mind. Unable to kill Shun, he breaks down mentally and shoots himself.
Final Revenge Arc
Kyou activates his brainwashed followers across Japan, triggering mass violence and chaos. His cult has evolved into a nationwide threat.
Shun returns to his old school for the final battle. Juutarou Kibe, a former war comrade of Shun’s grandfather, stands in his way. Dr. Kitami sacrifices himself in an explosion to protect Shun and Kawane. Though Kibe survives the blast, Shun ultimately kills him.
Kyou then reveals the truth. He and Shun were once childhood friends. A dangerous choking game they witnessed sparked Kyou’s obsession with death. After Shun once choked him during the game, something in Kyou broke. From that day forward, he became fascinated with concepts of pain, murder, and death.
Inside the school gym, Kyou traps Shun along with Kawana, Azuma, Hanaoka, and two police officers (Mizuki Anzai and Oota). He forces Shun into a twisted “love selection” game. Whoever Shun chooses will be executed using a torture method of their choice.
Anzai is killed first before the game even begins. Hanaoka chooses death through blood loss using a transfusion machine. Azuma dies slowly from Momoki’s poison, losing her senses one by one.
It is revealed Momoki and Kyou had a child named Aiji, who died from neglect while she waited for Kyou to visit. Reo uses the preserved baby corpse Aiji as a distraction and rescues Shun, Kawana, and Oota.
Fifth Victim: Kyou Shigoku
A poison gas fills the town and Kawana and Reo try to stop it leaving Shun to return and confront Kyou alone. During their final fight Shun tries to shoot Kyou but Momoki steps in and stabs Shun with the same poison given to Azuma. It is then revealed that Kyou cannot feel physical pain due to a psychological condition. However, when Shun tells him he hates him and regrets ever understanding him, Kyou finally experiences emotional and physical pain. For the first time, Kyou suffers. Shun beats him relentlessly and sets him on fire, finally killing him.
Ending and Aftermath
News about Kyou’s cult are exposed worldwide. Kawana and Reo continue Juujika’s mission, carrying on the cycle of vigilante assassinations. Shun is implied to wander as a restless spirit together with the five bullies he killed.
Kyou Shigoku Explained
Why does Kyou Kill in the First Place?
Kyou believes that death is salvation.
He has never truly experienced pain or understood normal human emotions like love. The only moment in his life that felt real was when Shun choked him and gave him a near death experience. In that moment, he felt something intense and overwhelming. To him, it felt blissful.
Because of that, he developed the twisted belief that if death felt that good, then everyone should experience it. He takes death lightly and never truly acknowledges the suffering that leads up to it.
Why did Kyou Bully Shun?
Kyou’s ultimate goal was to become a killer without motive. He wanted to indirectly kill Shun, whom he labeled Experiment A, by pushing him into depression and eventually suicide. To do this, he created a group of bullies around Shun.
He did not bully Shun purely for entertainment. Later in the story, it becomes clear that he still sees Shun as a friend in his own distorted way. He believed that if death was blissful, then Shun should experience it too.
But Shun did not follow Kyou’s expectations. Instead of breaking, he grew stronger. He transformed his sadness into hatred and anger and that anger became the fuel for his revenge.
Why and How Did Kyou Create the Revolutionary Club?
Kyou is extremely talented at everything he does, which makes ordinary life boring to him. Since the only thing that ever fascinated him was the near death experience he felt, he created the Revolutionary Club as an entertainment to surround himself with violence, pain, and death.
Because he has never truly suffered pain, he views it lightly. To him, death and the pain that leads up to it are beautiful phenomena that everyone should experience.
Many members of the Revolutionary Club were either forced to join or were already victims of abuse and trauma. Kyou manipulates that trauma to recruit them.
For example, Momoki was constantly criticized by her parents for being a lesbian and had her entire life controlled. Kyou encouraged her to kill her own parents as a way to gain freedom. This twisted sense of liberation attracted more members. Those who joined would then bring in others through referrals, expanding the organization like a cult.
Ending Explained
The ending is intentionally vague. While Kawana and Reo continue Juujika’s mission, carrying on the cycle of vigilante assassinations, what happens to those who died are shrouded in mystery.
It is implied that Shun becomes a wandering spirit observing the aftermath of everything that happened. He appears to be stuck alongside the five bullies he killed. This connects directly to the title Cross of the Six, which likely represents Shun and the five bullies.
Meanwhile, the innocent victims seem to have moved on to a peaceful afterlife. This suggests that Shun, despite being the protagonist, is just as sinful as the people he murdered.

Will Juujika no Rokunin Get an Anime Adaptation?
An amateur animation studio called Nimbus Studio apparently already created an unofficial mini TV series adaptation of the manga. It is even listed on IMDb.
I have not watched the mini series myself, but they plan to remake it with improved dubbing and animation. This new remake teaser seems to have smoother animation with better voice acting. All other teasers are currently on an upcoming premiere on their YouTube channel.
Nimbus Studio was founded by Maikel Lekina. The series was reportedly available only through their app called Nimbus TV and not on any major streaming platforms. Unfortunately, the app is currently unavailable and is expected to return in July 2026. Since they are a small studio, it is difficult to find detailed information about them. Most updates seem to come from their Discord, Tiktok, YouTube, or X accounts.
Personally, I think it is very unlikely that this manga will ever receive an official anime adaptation. While series like Berserk have received adaptations despite heavy violence and gore, Juujika no Rokunin repeatedly depicts sexual abuse, self harm, and extreme brutality. Some of these scenes feel overused purely for shock value. Because of that, it may be too controversial for mainstream studios.
Honest Review and Final Thoughts
I feel that the series was dragged out at times. After Kyou created the Revolutionary Club, Shun faced many unnecessary obstacles before finally reaching him. It made parts of the story feel stretched.
Kyou’s death also felt rushed. Shun was already poisoned and had limited time left, which made the final confrontation feel compressed compared to the long buildup.
It was always expected that Shun would die alongside his revenge against the five bullies. The title Cross of the Six foreshadows that outcome clearly.
That said, I was uncomfortable with the repeated use of sexual abuse for shock value. Some female characters experienced it multiple times. There were also scenes involving torture and abuse of animals such as cats and bunnies, which did not sit well with me.
Overall, I think it is a strong read for people who enjoy extreme psychological revenge stories and graphic violence. However, I would not recommend it to younger audiences or readers who are sensitive to disturbing content.
If you liked Juujika no Rokunin, you may also enjoy Maria no Danzai. It has a similar revenge theme. In that story, a loving mother loses her son to five bullies and seeks revenge by going undercover as their school nurse.
