Kiznaiver (キズナイーバー) 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 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), and "bond/connection" (絆); other than the word "naive" (ナイーブ).
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.
