Kiznaiver (キズナイーバー, Kizunaībā) is a 2016 Japanese anime television series produced by Trigger, Aniplex, and Crunchyroll and written by Mari Okada. The series features character designs by Shirow Miwa.[4] It also features the directorial debut of Hiroshi Kobayashi, assistant director of the anime Rage of Bahamut and episode director for Kill la Kill. Kiznaiver follows a group of high school students who are chosen to be a part of an experimental program which creates bonds between people by forcing them to share each other's pain. It is thematically similar to Trigger's previous works, which deal with problems attributed to character interaction.[5] The series' title and premise are based upon the Japanese words for "wound/scar" (, kizu), and "bond/connection" (, kizuna).


Kiznaiver takes place in the futuristic, fictional Japanese town of Sugomori City. While the city appears to be normal, it was created to test a large-scale experiment known as the Kizna System, which connects people through shared pain and suffering, both physical and emotional. Those who are connected to the system are called "Kiznaivers".

A few days before the start of summer vacation, a mysterious and seemingly emotionless girl, Noriko Sonozaki, tells high school student Katsuhira Agata and several of his classmates that they have been selected to become Kiznaivers. Sharing each other's pain allows them to build bonds between their differing lives and personalities.

High school student Katsuhira Agata is a boy who seems to feel no emotions or pain, and a frequent target of bullying. Shortly before summer break, he meets a strange girl, Noriko, who pushes him down a flight of stairs as part of an experiment. He wakes up in an underground hospital room with several classmates, where Noriko tells them that they are all now Kiznaivers, connected through the experimental Kizna System via scars on their wrists. Katsuhira learns that the fall would have killed him if the Kizna System hadn't dispersed his injuries across the other Kiznaivers.

Noriko traps the Kiznaivers in the building and tasks them with introducing themselves to the group; if they don't cooperate, they're subjected to painful and life-threatening situations. It's eventually revealed that the true goal is to have them confess secrets to each other, such as an unexpected fear of dogs. Katsuhira introduces himself as someone who feels nothing; when his childhood friend, Chidori, confesses her love for him, he suddenly feels happiness and reintroduces himself as someone slowly learning his own feelings.

Noriko tasks the six Kiznaivers with tracking down a missing seventh member, whose pain they can all feel. After no one in their class reacts in pain when the Kiznaivers harm each other, they deduce the missing member to be Yoshiharu Hisomu, the only student that has been absent since the start of school. Later, they confront Hisomu at his apartment; he runs, and they chase him. Katsuhira jumps from an overpass in an attempt to convince Hisomu they're all connected, landing painfully inside a nearby convertible, at which point the group learns Hisomu is sexually aroused by pain. Meanwhile, Noriko gives a conference regarding the Kizna System to government officials with the aim of the "true connection".

In his apartment with the others, Katsuhira awakes from flashbacks involving a young Noriko. Hisomu explains to the group how he takes pleasure in fatally dangerous and unexpected pain; he submitted to the Kizna experiment because Noriko had promised him stimulation. The group further bonds at school the next day, most of them considering the others to be their friends.

On the way to a "Kiznaivers training camp" at a resort inn the day after, Noriko tells the group about the history of the city and the Kizna program. Chidori jealously notices a relationship growing between Katsuhira and Noriko. Meanwhile, another car carries Kamaishi and Yoshizawa, two of Katsuhira's bullies, to the camp, and it's revealed that they are also Kiznaivers.

As the group settles in at their inn, Tenga tries and fails to bring Katsuhira and Chidori closer together. The group meets Kizna Committee members Yamada and Urushibara, and they discover that Kamaishi is a Kiznaiver. Chidori berates Kamaishi about the pain that his bullying of Katsuhira has caused her, which makes Katsuhira realize that he had never been alone in his suffering.

Honoka experiences more visions of her past involving a girl named Ruru. While the Kiznaivers (excluding Yuta) spend the day at Katsuhira's apartment, Honoka leaves alone until she is stopped by Nico, wanting to walk home with her. When she pries on her about her ideals of friendship, Nico calls herself stupid, with her words resulting in Honoka's inner pain transferring to the rest of the group. While Noriko discusses the Kizna experiment's financial situations, a mysterious man approaches Honoka. At a restaurant, while Yuta's friends are enamored by a girls manga under the pen name Charles de Macking, a line in the manga strikes a chord within Yuta, prompting him to leave. As an editor attempts to negotiate with Honoka to obtain the rights to produce her manga as a movie, he is then stopped by Yuta. Claiming to have followed the painful sadness within her, she detests him and soon runs off. As Yuta regroups the other Kiznaivers while sharing with them a piece of Honoka's past as a manga author, Noriko assigns a special mission to them to save her, leading all of them back into the school. When Honoka arrives first noticing the crowd of people and a TV crew, her attempts to escape are stopped by the filmers wanting an interview with Charles de Macking, attracting the attention of the crowd as well. Bombarded by the media and bystanders, Honoka breaks down with a massive pain signal transferring through the Kiznaivers. Despite the intense pain, the rest of the group manages to drive away the filmers and the crowd, deeming the mission complete. However, when Honoka realizes the scenario in regards to their mission, she runs off as Nico emphasizes how severe her case must be if a seventh of the massive pain they all felt had accumulated in herself. While the group decides to confront Ruru's family to connect Honoka's past, Katsuhira first confronts Noriko to express his disappointment in her by how half-hearted the mission felt.

As the group confronted Ruru's family amidst a tense atmosphere, her parents tell them about her terminal kidney illness, her connection to Honoka, and a mysterious parting of ways before her inevitable death. When Honoka reminisces of their time together, it is revealed that as a manga artist duo under the name Charles de Macking, they were the best of friends while only having each other to rely on. However, as work with the manga progressed, Ruru developed feelings for Honoka, causing her to create the wedge that would drive them apart. Moments before Ruru created the final chapter, Honoka expressed her desire to stop drawing manga with her, and while she takes it lightly, she gives a traumatizing message of resentment to Honoka as the final scene from the chapter. As Honoka's heartache resonates with the other Kiznaivers, they set out to form a lasting friendship with her. The next day, the group reaches out to a withdrawn Honoka within her room, and while she does not respond to their calls, they decide to personally confront her to ask if they could be friends with her. Despite not working as planned, Yuta assures the group that Nico's outburst of concern actually touched her heart as evident with their shared pain. As the rain quickly pours down, Honoka goes for a walk and encounters Yuta reading her manga, and much to his surprise, found out that Honoka did not read the final chapter. While she assumes Ruru's hateful message was laid inside, Yuta convinces her to read the final chapter, while telling her she lied about the ending. When asked about the reason for breaking off Ruru's friendship, she did not want to bear the burden of her death should they have stayed together. As they meet up with the other Kiznaivers attempting to blow up fireworks at the beach, Honoka tells them to go for a swim, which they reluctantly do despite the rain and the time. Reaching the end of the manga, her eased heart is felt by the Kiznaivers, as Ruru's message was revealed to have forgiven her. While Honoka states that she cannot be friends with the group, she assures them that being Kiznaivers makes them closer than friends or lovers, remarking to her late friend's message from their manga.

Yamada and Urushibara review the latest analyses from the Kiznaivers' previous mission while noticing Honoka's emotions resonating on a deeper level above pain, prompting the start of another mission. In the middle of a typhoon affecting Sugimori City, the Kiznaivers are spending time together until several Gomorin kidnap them and are taken back to the school. There, Yamada shows the group a video presentation covering the details of a previous Kizna experiment done many years ago on children to connect the entire spectrum of sensations including pain. While they question the previous experiment's inhumane methods despite their true aim for world peace, the Kiznaivers are left at school with another mission to get home safely. While the group plans an escape however, Yamada makes preparations for the true purpose of the mission, to forcefully pair certain Kiznaivers to instigate a romantic connection. Using a flowchart of pairings, they deduce Yuta's feelings for Honoka, as well as Nico's love for Tenga and his love towards Chidori, who still likes Katsuhira. When Noriko traces Katsuhira's romantic feelings to her, she decides to confront him personally despite Urushibara's wishes, wanting to reciprocate his feelings he said "from before". Meanwhile, Yamada manipulates the pairings by separating Tenga and Nico, leaving Chidori and Katsuhira to find a way out. As Nico's flustered emotions are transmitted, an irritated Hisomu attempts to trigger pain and angers Honoka by touching on her internal trauma, leading to Yuta chasing after her. As Yamada confirms the romantic bond between Honoka and Yuta, Chidori and Katsuhira are led to the roof, where she attempts to confess her feelings to him. After her confession however as Noriko comes out to confront him, Katsuhira runs outside and saves her from a crumbling statue, to which a glow emanating from her collar is seen. As she takes it off, she reveals to have her own Kizna Scar on the back of her neck, much to Katsuhira's surprise.

As Noriko reveals her own Kizna Scar to Katsuhira, she tells him of her existence inside of him before collapsing. While Tenga and Nico follow what seems to be Chidori's inner pain to her despairing over Katsuhira's feelings, the group responds to a beaten up Hisomu, in which they take shelter in the AV room. Safe from the Gomorin attacks, Yamada screens Katsuhira and Noriko conversing from the gym onto a projector. As the others watch, Chidori becomes more unnerving at the sight, while Noriko's possession of a Kizna Scar is revealed to the others as ties to her past and Katsuhira's visions. While Tenga rallies the group to head to the gym, a reluctant Chidori comes along due to Nico's persuasion. While Urushibara questions the Kizna experiment's boundaries, Noriko vividly tells Katsuhira of the time they spent 12 years ago with the other Kiznaiver children. As the present-day Kiznaivers experience a tremendous bout of pain, Hisomu traces it back to Katsuhira, much to Chidori's concern. Clenching on to his glowing chest, Noriko unbuttons his shirt to reveal a second Kizna Scar on his body. Reaching out to hug Noriko, Katsuhira pieces together his past, welling up with emotions for the first time since the start of the second Kizna experiment. As the group arrives, Katsuhira responds to Chidori's inner pain as she then runs off, forcing a furious Tenga to yell at him to chase after her. Confronting Noriko, Tenga and the others respond to Nico's emotions, running off as well after Noriko tells Tenga about Nico's hidden feelings for him. As Katsuhira grabs Chidori's hand while she pleads to let her go, Katsuhira and the others hear her inner voice wanting to be held, as their Kizna Scars glow red. As Urushibara goes against Yamada and tries to stop the kids before things get any worse, Katsuhira holds Chidori until a jealous Tenga starts beating him up as his inner feelings for her resonate through the group. As Nico's and Honoka's inner sorrows are resonated as a result of their broken friendship, the culmination of everyone's inner thoughts leaves the group writhing in pain as their red Kizna Scars flicker. When the rain clears out, Urushibara and Noriko confront the recovering Kiznaivers and assures them that their Kizna will be released once summer is over.

The group decides not to keep in touch until the next school year begins, by which point their Kizna Scars have all disappeared. Noriko attempts suicide in a drastic bid for proof of the Kizna experiment's results, but instead falls unconscious while Katsuhira's remaining Kizna Scar reacts to her.

Details of the first Kizna experiment's failure are revealed: Katsuhira and Noriko had been among nineteen test subjects twelve years before. Rather than pain being evenly distributed among them all, Noriko had received the full force of everyone's pain. She began taking medicine to numb her senses, which affected the other children as well, including Katsuhira.

Noriko attempts suicide by jumping off a bridge while black Gomorin share her pain with the entire city, in an effort to unite its citizens. Katsuhira tries to save her; they fall together and survive. Some time later, Katsuhira and Noriko have begun dating and experiencing emotions. Yuta and Honoka have also begun dating, as well as Chidori and Tenga, though Nico still pines for Tenga.
