# Kiznaiver

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. 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 seven high school students who are chosen to be a part of an experimental program promoting world peace which creates bonds between people by forcing them to share each other's pain. The series' title and premise are based upon the Japanese words for "wound/scar" (傷, kizu), and "bond/connection" (絆, kizuna); other than the word "naive" (ナイーブ, naibu).

## Plot

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.

He wakes up in an underground hospital room with five other classmates, where Noriko tells them how she abducted and experimented on them, enlisting the aid of people dressed as white Gomorin, Sugomori City's mascot. However, all but Katsuhira leave the room in disinterest. As Katsuhira learns that the fall would have killed him if the experiment had not dispersed his injuries across the other classmates, Noriko reveals that all the classmates are now Kiznaivers, connected through the experimental Kizna System via scars on their wrists. ||||||

This feeling occurs more than once during the day, prompting Noriko to task the six Kiznaivers with tracking down a missing seventh member, whose pain they all can 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. They try to confront Yoshiharu at his apartment, but he runs away and a chase ensues. Finding Yoshiharu by an overpass, Katsuhira jumps off in an attempt to convince him that they are all connected.

After Yoshiharu finally shows up to class, Nico advises the Kiznaivers to exchange email addresses as a step to become friends. Noriko invites the Kiznaivers to a "summer camp" at a resort, where she later informs them about the history and her involvement of the Kizna System experimented in Sugomori City. On the way through the woods, Chidori jealously notices a relationship growing between Katsuhira and Noriko, much to Hajime's attention. Meanwhile, another car approaches the resort carrying Kamaishi and Yoshizawa, two of Katsuhira's bullies, revealing that they are also Kiznaivers. ||||||

Meanwhile, Honoka reminisces about her time with Ruru when they were a manga artist duo under the pen name Charles de Macking. They were best friends, but Ruru started developing feelings for Honoka, which created a wedge and drove them apart, so Ruru made the last chapter on her own. As Honoka's heartache resonates within the other Kiznaivers, they set out to form a lasting friendship with her. Although a withdrawn Honoka ignores their calls in her room, her heart is touched when Nico has an outburst of concern. During a downpour, Honoka encounters Tsuguhito reading her manga, but he is surprised to learn that she has never read the last chapter. As Tsuguhito and Honoka meet up with the other Kiznaivers attempting to light up sparklers at the beach, Honoka suggests that they should swim, despite the weather.

As a typhoon approaches Sugimori City, the Kiznaivers are kidnapped by several Gomorin and taken back to the school. Yamada shows them a slideshow presentation covering the details of a previous Kizna experiment done many years ago on children to connect the entire spectrum of sensations including pain. When Hajime questions the inhumane methods despite the true aim for world peace, Yamada leaves the Kiznaivers at school with another mission to get home safely. However, this is part of Yamada's plan to stimulate romantic connections among the Kiznaivers, who have been chased to separate areas of the school and must find a way out.

| Noriko collapses after telling Katsuhira that he exists within her. After the other Kiznaivers take shelter in the audio-visual room, Yamada remotely screens Katsuhira and Noriko in the gymnasium onto a projector, revealing to the others how Noriko's Kizna scar is tied to Katsuhira's visions of the past. As Hajime rallies the other Kiznaivers to the gymnasium, Katsuhira is finally able to piece together his past from twelve years ago with other experimented children. Noriko unbuttons Katsuhira's shirt, which unveils a second Kizna scar on his chest, and he embraces her in tears. When the other Kiznaivers arrive, Katsuhira is prompted to chase after Chidori. Katsuhira grabs Chidori's hand and her Kizna scar glows red, while her inner voice begs to be held. As Urushibara goes against Yamada and tries to stop the Kiznaivers before things get any worse, the Kiznaivers begin to suffer from their inner sorrows as a result of their broken friendship, and the culmination of everyone's inner thoughts leaves them writhing in pain as their red Kizna scars flicker.

| The Kiznaivers decide not to keep in touch until the next school year begins, due to being able to sense each other's inner sorrows, which by then all their Kizna scars have disappeared. After Yamada starts his class with discreet humiliation for the Kiznaivers, this encourages Nico to reconnect with Katsuhira and Yoshiharu. Noriko attempts a suicidal jump from the roof in a drastic bid for proof of the results of the Kizna System, and Katsuhira's remaining Kizna scar reacts to her. Katsuhira, Nico, and Yoshiharu find the passage into the underground subway station, meeting up with Urushibara, who says that Noriko only fell unconscious. Urushibara further explains that Katsuhira and Noriko were among nineteen test subjects during the first Kiznaiver experiment twelve years ago. Noriko received the full force of the pain rather than the pain being evenly distributed among the others. She began taking medicine to numb her senses, which affected the other children as well, including Katsuhira. When Katsuhira finds five other children who were released twelve years ago, childhood memories pour out of him as they look at him with still faces. ||||||

| While Katsuhira is still overwhelmed by his past before him, a bedridden Noriko confides in Yamada that she jumped off the roof because she was searching for something that she saw twelve years ago. After saying goodbye to Urushibara, Nico points out to Katsuhira and Yoshiharu that they will have to connect on their own, since they cannot rely on the Kizna System anymore. At the apartment, Katsuhira calls Chidori to tell her that he met the five released children described as dolls, apologizes to her for never understanding, and thanks her for protecting him. The next day, as Katsuhira and Noriko interrupt class to talk in private, Katsuhira believes that he wanted to help Noriko in the Kizna System in order to regain his pain, but she says that he is wrong. After class, Katsuhira gathers the other Kiznaivers to assess the validity of their friendship since the very start. Later talking to Urushibara, the Kiznaivers discover that they are still bonded even though they are no longer connected through the Kizna System.

Kamaishi and Yoshizawa have received special Kizna scars on their abdomens, but Hajime is still strong enough to defeat them. As Katsuhira and Urushibara finally approach Noriko at the main bridge which has slightly opened, the other Kiznaivers express their friendship in the Kizna System. However, Katsuhira wants Noriko to share her wounds with him and let go. Noriko attempts suicide by jumping off the main bridge and plunges into the river below. Katsuhira falls in and tries to save her, both of them surviving in the end, with Katsuhira rejoicing over being able to feel pain again. Tsuguhito and Honoka share an ice cream cone together, hinting that Honoka wants Tsuguhito to put on some weight.
