Rags Town is the garbage dump of Japan. The place where people who want to forget their pasts run to. In this town, where the rules strictly forbid asking about the past or getting to know people, there is small detective agency called S&A Detectives. The story revolves around Ayamana, the inseparable pair of misfit wannabe detectives, the case Manami takes on impulse, and the trouble that arises from it. On the case they find a woman who is abnormally hot, and who is being chased by a bunch of women with guns. After being dubbed Sara, the detectives try and figure out just what is going on with her. At the same time, all over town teenage girls are burning up and turning into glass. The government is covering everything up, but the detectives, as well as a nosy reporter and the local police, are determined to find out what is happening.

Kou Kitamura and Aoba Tsukishima are often at odds—even though their families happen to be close friends and business partners. Although the only child of a sports shop owner, Kou has never been interested in playing baseball. Despite this, he possesses an impressive batting ability honed by frequent visits to the local baseball batting center run by the Tsukishima family. On the other hand, Aoba loves to play baseball and is a star player with exceptional pitching form. However, these two seemingly complete opposites share something very important to them—Wakaba Tsukishima, Aoba's older sister and Kou's destined sweetheart. Admired by the quarrelsome duo, Wakaba often finds herself the catalyst to their never-ending rivalry. But whether or not they realize that they have more in common than either would care to admit, only time will tell. The game of baseball may just be what the pair needs to ultimately overcome their own personal struggles.

Adult people all over Japan had been captivated by 20th Century Expo, theme parks that reenacted good old days of the 1970s (the last days of Japan's high economic growth). One day the adults disappeared into the theme parks, leaving their children abandoned. That was a plot by Yesterday Once More, an organization who despises the 21st century and tries to bring Japan back to the 20th century with the dreams and hopes. Shinnosuke and his parents, Hiroshi and Misae, fight against the plot of Yesterday Once More in order to live together with family in the 21st century. (Source: Manabu Tsuribe)

Due to the advent of modern technology, kids have abandoned their crayons and paper for electronic tablets, causing the imaginative energy emitted from children's doodles to reach an all-time low. Consequently, the Rakuga Kingdom in the sky, powered by such energy, is now at risk of collapsing onto the cities below. For any hope to avoid such a catastrophe, the kingdom's princess hastily seeks out a hero from Earth capable of wielding the Miracle Crayon. While the kingdom's reformers arrive on land to seize Earth, the magical crayon finds itself in the hands of Shinnosuke Shin-chan Nohara. In a journey that will test the limits of childlike imagination, Shin-chan must harness his creativity to secure the safety of his home and restore peace to both worlds.
