Gridman the Hyper Agent: boys invent great hero (電光超人グリッドマン boys invent great hero Denkō Chōjin Guriddoman Boizu Inbento Gurēto Hīrō) is an animated short based on Gridman the Hyper Agent and its sequel picture novel Gridman the Hyper Agent: The Demon King's Counterattack. The short was directed by Akira Amemiya and produced by Studio Trigger for the Japan Animator Expo and debuted on January 16, 2015. It features the return of Takeshi Todo and the brief appearance of Gridman Sigma, another Hyper Agent like Gridman who never made it to the show's final cut.

The entire short took place 22 years after Gridman's final battle with Kahn Digifer. Takeshi Todo, a former brainwashed servant of Khan, reflects on the past incidents as monster attacks take place in real life. Using the Acceptor, he transforms into Gridman Sigma before facing the monsters.


22 years ago, a boy named Takeshi Todo, attempted to take over the world together with the devil of the Computer World. He reformed himself after the battle and now needs the power of the Hyper Agent. Again, the evil is going to appear in the real world. A materialized monster is now approaching! Enter the battle code! The Access Code is..."GRIDMAN".
