Katsuhira Agata is a quiet and reserved teenage boy whose sense of pain has all but vanished. His friend, Chidori Takashiro, can only faintly remember the days before Katsuhira had undergone this profound change. Now, his muffled and complacent demeanor make Katsuhira a constant target for bullies, who exploit him for egregious sums of money. But their fists only just manage to make him blink, as even emotions are far from his grasp. However, one day Katsuhira, Chidori, and four other teenagers are abducted and forced to join the Kizuna System as official Kiznaivers. Those taking part are connected through pain: if one member is injured, the others will feel an equal amount of agony. These individuals must become the lab rats and scapegoats of an incomplete system designed with world peace in mind. With their fates literally intertwined, the Kiznaivers must expose their true selves to each other, or risk failing much more than just the Kizuna System.

Seiya Kanie, a smart and extremely narcissistic high school student, believes that the beautiful but reserved Isuzu Sento has invited him on a date at an amusement park called Amagi Brilliant Park. Much to his chagrin, not only is the location a run-down facility, the supposed date is merely a recruitment tour where Sento and Princess Latifa Fleuranza, the owner of the theme park, ask him to become the park's new manager. Their cause for desperation? As stipulated in a land-use contract, Amagi has less than three months to meet a quota of 500,000 guests, or the park will be closed for good and the land redeveloped by a greedy real-estate company. Seiya is won over by the revelation that Amagi is no ordinary amusement park; many of its employees are Maple Landers—mysterious magical beings who live in the human world and are nourished by the energy created by people having fun. Entrusted with the hopes and dreams of this far-off enchanted land, Seiya must now use his many skills to bring Amagi back on its feet, or watch it crumble before his eyes.

The cheerful Yuuki Cross and the gruff Zero Kiryuu are members of the disciplinary committee at Cross Academy, which houses two very distinct classes: the Day Class and the Night Class. Their job consists of upholding order between the classes when they switch out. While that may not seem like an especially difficult task, the Day Class is unaware of the truth behind the Night Class—their utterly gorgeous students are vampires. Ten years ago, Yuuki was saved from a vampire attack by Kaname Kuran, a Pureblood vampire. Now, Kaname is the leader of the Night Class, and Yuuki's disciplinary committee position allows her to see him again, making her feelings for him grow complicated. Meanwhile, Zero bears a white-hot hatred of all vampires and believes they can never live in harmony with humans. But a secret from Zero's past soon threatens the fragile peace of all at the academy, and things may never be the same again.
