Nayuta Azumi is a young game-developing prodigy who is known as an indie developer—someone who creates games on his own without the help of a major company or distributor. He goes by the name “John Doe” and is known as the “Banksy of the game industry,” as no one knows his true identity. However, he now works at an auto body shop and lives a quiet life away from game development. Meanwhile, a long-established toy manufacturing company called Atom Toys is struggling to compete with overseas prices, thus putting them in danger of going out of business. To turn the company around, Atom Toys begins its search for John Doe so that they can enter the game production business. With no funds or know-how, Atom grasps at straws and desperately scrambles to get in touch with this John Doe.
