For three long years, Akira has been saving to buy his very own computer. So when the Model 9821 finally goes on sale, he races to the store only to discover that it sold out in just 5 minutes! Yet, as luck would have it, Akira also manages to stumble across a man who just happens to be willing to sell him the exact model he was looking for! Unfortunately, Akira doesn't look close enough at the packaging. Instead of the 9821, he ends up with a Model 2198 - a super-advanced, biomechanical computer girl named Mimi!
