Six kids finish a soccer match and gather to play a video game together. When they defeat the final boss, reality glitches. A portal opens and sucks all of them into the game world itself, a colorful sci-fi landscape called Eureka. Tomoru, Mio, and Dai wake up alongside Professor Galileo, the game's creator who somehow got trapped inside his own creation. The professor explains the only way out: complete missions that appear across the world. Problem is, he has no idea how many missions exist or what order they need to happen in. With no better options, Tomoru drags the professor along on every mission while Mio and Dai follow, treating this digital prison like a series of increasingly weird puzzles to solve. Each mission brings new obstacles, ridiculous logic, and moments where the game's rules feel more like suggestions than actual laws. It's part adventure, part comedy, entirely absurd. Six kids figure out that getting home means embracing the chaos of a world that wasn't designed to be entered by humans, let alone understood by them.
