Plot Jūjika no Rokunin depicts the vengeance of Shun on his bullies. Shun Uruma, a sixth-grade student, is subjected to severe bullying by five of his classmates: Katsumi Senkouji, Yuuga Ushiro, Hiro Madoka, Daichi Kuga, and their leader, Kyou Shigoku. Kyou regards Shun as an experiment, calling him "Experimental Subject A", attempting to determine how much abuse will drive a person to suicide. His only peace was with his brother, Kakeru, who loved him, and his parents, who when they soon found out what was happening to their son, moved Shun to another school; Kyou, unwilling to let the experiment end, arranges an attack that kills Shun's mother and father and puts Kakeru in a vegetative state. Shun moves in with his grandfather, Noboru, who served during World War II in the Kitayama Unit, a clandestine military organization specializing in assassinations and other covert operations. Realizing that Shun intends to kill the bullies who did this to him, Noboru agrees to train him in combat, survival, interrogation, and killing, but on one condition: Shun must spare any of them if they actually repent for what they've done.
Pre time-skip Four years later, Shun sets out on his revenge, starting with Senkouji, whom he kills and tortures after Senkouji initially seems to have changed for the better. Shun then saves a girl, Chizuru Azuma, from an attacker; she gets acquainted with him, and she develops feelings for him soon after. Shun proceeds to hunt down his other bullies, torturing and killing each of them. During the process, he reunites with Jun Shirakawa and his twin sister Kaname, who were classmates with Shun. Upon confronting the leader of the bullies, Kyou Shigoku, he is revealed to be the leader of a cult called The Revolutionary Club, and he is accompanied by his researchers, people working for him in the Revolutionary Club; the most notable are Momoki and Andou.
Jun and Shun are forced to play a twisted game of rock, paper, scissors in which the loser of each round decides the fate of his sibling, Kakeru and Kaname for Shun and Jun respectively. In the last round, the game gets interrupted by Shun's grandfather, who has escaped his imprisonment. He dispatches two of the researchers before Andou kills him with a chainsaw. Shun, after seeing his family get killed, attacks Kyou one last time before he gets left alone at the crime scene, ultimately getting him arrested for 5 years.
Post time-skip During the time-skip, Uruma loses his memories before joining an organization dedicated to targeting criminals called "Juujika-san". He is wearing a cross mask and a black robe to cover his identity while working for the organisation. After he regains his memories, Shun tracks down Andou to a remote island that's owned by the Revolutionary Club and he travels towards it as a supposed new recruit. On the island he meets Reo and Hanaoka. Reo is the adopted daughter of Kurusu, another recruiter of the Revolutionary Club. After Shun gets discovered, he gets tortured by Andou. He eventually escapes and tortures Andou and Kurusu to death with Reo. He retrieves a phone and with Andou's fingerprint to track Kyou.
Dr. Kitami, Kawana and Shun return to "Juujika-san" and everything goes back to normal for a while before Jun abducts Shun and he makes him watch the death of Azuma, who is revealed to be a clone of the real girl. Shun remembers how he lost his memory, which is revealed to be because of Jun shooting him with a gun. After that they decide to return to the place where it all started, the middle school Shun shared with Kyou. Along the way he meets a colleague of his grandfather in the Kitayama Corps, Juutarou Kibe who wants to kill the Uruma bloodline because Noboru stole a girl that he liked, and Shun manages to defeat him. He and Kawana are confronted in front of the school by the parents of the bullies he killed.
Shun then makes his way inside, seeing Kyou and they have a conversation before he enters a machine that returns him to his childhood. It is revealed that Shun and Kyou were best friends before he went rogue and start bullying him. Shun soon gets forced by Kyou to play a twisted version of a game that he has to choose which woman that is close to him die until the last one standing becomes his girlfriend. The women there are Azuma, Kawana, Hanaoka, Oota (a police officer that knows Shun from before the time skip), and the wife of a police officer that Shun killed. As the game progresses Shun does everything that he can do to not kill anyone but he is forced to press a button, which kills the police officer. From that point onwards Kyou forces the game to continue, and a computer generated arrow chooses Hanaoka as the next target. After her death the arrow chooses Azuma, who is injected with a serum created by Momoki that makes her lose all of her senses before she died as well. Reo successfully interrupts the game when she brings in a baby that is mummified, revealed to be a child of Kyou and Momoki. The current latest chapter reveals Shun escaping with the rest of the girls that has survived and Reo, and how Kyou "kills" the baby with a shotgun before aiming at Shun. Luckily for Shun and Reo, Momoki kisses Kyou as they escape. After that Kyou hits Momoki and the readers are revealed a flashback that shows the start of a sex scene between Momoki and Kyou.
Later Shun and Kyou finally face off which results in both Kyou and Uruma's deaths.
