Higashiyama Haruto is a 34-year-old Japanese history teacher who combines good looks with an honest and friendly personality. When he has been assigned to Nitaka High School, a school for advanced students, Haruto immediately attracts the attention of his female students. But he has a secret that he cannot tell anyone; he wants to be killed by a beautiful high school girl. Obsessed with such a bizarre desire, Haruto approaches four beautiful girls of different types, Maho, Aoi, Kyoko, and Aika, according to the perfect crime scenario he has devised. Who among the four is the high school girl that Haruto has been longing to be killed by for nine years?

Five different directors adapt the works of Japanese author Otsuichi in this collection of unconventional live-action and animated shorts. A woman is murdered under odd circumstances in the title film, "Zoo"; twin sisters are treated differently in "Kazari and Yoko"; two siblings find themselves trapped in "Seven Rooms"; a survivor learns about life and death in "When the Sun Shines"; and parents lose the ability to see each other in "So Far."

Teiichi Akaba is a student at a prestigious private male high school known for producing important politicians and bureaucrats. His dream is to become the prime minster and make his own country. To help achieve his dream, he wants to become elected as his school's student council president. The elected student president receives privileges and a better chance for promotions later in the political & bureaucrat world. A power struggle takes place surrounding the student election.

In the bleak, smoke-choked Keiko Town, a gang of boys forms the Hikari Club to destroy the corrupt adult world. But as they build an AI to carry out their mission, they can’t stop the one thing they fear most—growing up themselves.

Lychee Light Club takes place in an alternate reality where the Club does not fall into disarray after the completion of Litchi, the intelligent human-like robot the club invented to kidnap girls. The cult-like Lychee Light Club has had its ups and downs. Led by the enigmatic, beauty-obsessed Hiroyuki "Zera" Tsunekawa, the club has finally succeeded in using their fruit-powered robot, Litchi, to kidnap the beautiful Kanon. After accomplishing their goals, the Hikari Club has little to do other than delight in their newfound lives. From selling the technology that allows Litchi to run on lychee fruit, to modifying the robot to perform different tasks, there's no telling what antics the Lychee Light Club will get up to next!

A man makes a robot girl and tries to teach her the aspects of daily life. But what is his real goal? Hidamari no Shi is the fourth part of the five-part film Zoo, adapted from the first volume of Otsuichi's novels of the same name. It is the only part of the film made from animation; the other parts are live-action sequences.

The story is a variation on the Tom Hanks classic "Big," but instead of a boy finding himself in a man's body, a sick girl falls asleep one day and does not wake up again for 11 years. In the meantime, her baby sister, Natsumi (Rio Kanno), grows up to become a very studious and serious 12-year-old, studying hard at her summer juku (cram school). When her aunt, a free-spirited photographer (Karie Kahimi), goes missing in South America, her mildly scatter-brained mother (Kaho Minami) and father (Tetsuji Tanaka) go looking for her, leaving the girl, Natsumi, to look after her sleeping sibling, Ai (Rosa Kato). Yes, this is a clear case of child neglect, but Natsumi is such a no-nonsense, responsible type that it seems almost understandable. Soon after Mom and Dad leave, she notices that Ai, incredibly, is up and about, with the body of a woman, but the mind of an 8-year-old.
