You Pretend to Be a Nether Demon to Scare Me, but I Can Really Combine My Armor

Fang Ran, an ordinary college student, is out for a night run when he unexpectedly awakens a tokusatsu invasion System. As long as he completes the missions the System assigns, he can earn all kinds of rewards! For his first mission, the System sends him to a designated location to defeat a Netherworld Demon that has descended upon the human world. When Fang Ran arrives, he happens to find a prank video creator wearing a Netherworld Demon costume, holding a prop, and hiding in the shadows to scare people on livestream. Looking at the “Netherworld Demon” before him, claws bared, Fang Ran doesn't hesitate for a second. “Armor, assemble!” A brilliant light shoots into the sky as magnificent armor covers his body! The viewers in the livestream chat think it's all a staged performance with special effects, and flood the screen with cheers. Then Fang Ran casually strikes a steel lamppost by the roadside and knocks it over. The prank streamer is so terrified he wets himself. He scrambles away and yanks off his mask. “Bro, I'm human! I'm just making a video!” Fang Ran is just about to remove his armor when a chilling laugh rings out from the darkness. The real Netherworld Demon has appeared!
