In a world where every event was computer programs, mysterious monsters known as "Promin" maintain the world. However, many Promins have corrupted into bugs known as "Bugmin" like real-life viruses and bugs. Left alone, they may eventually turn into a big problem. The boy Yuuto, with Wanda, and the pair use a camera-like device and essential items to capture Bugmin. Promin themselves can do things like "accelerate," "spew fire," or "create," through an ability known as "Kamiwaza" (miracle), and can fend off Bugmin with it. At first, the Bugmin only cause little, bothersome things, but it will soon elevate into a global scale threat. Can one boy and one dog save the world?
