In the 21st century, mankind lives on two worlds. Following the collision of an ice asteroid, massive terraforming has made Venus a planet now capable of supporting life. Colonists from Earth tamed the hostile world and have thrived for four generations. But they also brought the darker side of humanity. Venus is about to get hostile again. Hiro Seno, a hotshot motorcycle jockey, witnesses the first strike against his country Aphrodia, by the rival nation of Ishtar. Huge battletanks and warplanes quickly lay waste to the city. The Aphrodian army is quick to mobilize and retaliate... and despite his opposition to warfare, Hiro finds himself fighting for his life on the front lines.

The earth shook. The sea roared. A far greater disaster followed. And then... There is a small house solitary standing by the seaside. A pigtail-braided girl is living there alone since that day. Mail is no longer delivered, but even this morning she's hanging out the laundry as usual. She's unaware that all around her, the clothes-pegs are quarreling, the pillow argues with the umbrella about the outside world, and the new toothbrush is unsuccessfully trying to be polite with the silent, old ones. Do things exist to be used until they are consumed or broken? Are they afraid of being thrown away once their life cycle is complete?

Among the high rises of steel pipes, meshed power lines, and faded neon lights, exists a game that children dare to play within the ruins of the old city. "Otokoyo," a secret game of hide-and-seek, one where all who play wear fox masks and only begins when seven have gathered. But it is no normal game, as all who have played it have gone missing. Many whisper it is the work of demons, but that is just a rumor... or is it? Kakurenbo follows the story of seven children as they play Otokoyo for the first time and discover why if you play, you never return.

A slapstick comedy on a bomb uproar, and a touching story about the ties between the Nohara Family and their dog Shiro. A film in the musical style including the scenes with inserted songs. When the Nohara Family enjoy a trip to Okinawa, a strange object like a flying saucer becomes stuck with Shiro's bottom. That is a special bomb dropped by "The Only Buttocks Aliens," and it has the power to destroy the whole earth. The space monitoring center "UNTI" (Unidentified Nature Team Inspection) begins to pick up the bomb, but a female terrorist group "Hinageshi Opera Company" tries to get the bomb and disturbs UNTI's work.
