The Hyper World (ハイパーワールド Haipā Wārudo) is the home world of Gridman. The inhabitants have a police force called Hyper Agents (ハイパーエージェント Haipā Ējento), of which Gridman is a member. They hunt down criminals, such as Khan Digifier.
It is parallel to the Computer World (コンピュータワールド Konpyūta Wārudo) which Gridman can cross to.
