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.

In a peaceful, disarmed world where small robots are utilized as housekeepers, villains act with huge robots instead of weapons. Dr. Keewee converts Michael’s robot into a transformable one in order to teach them a lesson. This is the birth of Galatt, the town hero.

Aum Shinrikyou is a Japanese doomsday cult founded by Shoko Asahara in 1984. It carried out the deadly Tokyo subway sarin attack in 1995 and was found to have been responsible for another smaller sarin attack the previous year. The cult created its own studio called MAT (Manga, Animation, and Team) in 1991 for the sole purpose of recruiting otaku into their cult. This 10 episode OVA mostly focuses around Asahara himself being Christ. All 10 episodes were sold separately during its initial release but a compilation is available on the cult's official YouTube channel.
