Eerie Descent: Did I, a Kamen Rider, Wander Onto the Wrong Set?

Zhou Cheng transmigrates, but gets a Kamen Rider System that lets him unlock Showa, Heisei, Reiwa, and even future Kamen Riders by completing missions! Just as Zhou Cheng thinks he can teach the Heisei brats a lesson with Showa-style thuggery, and show the Reiwa kids what Heisei nostalgia is all about, he realizes... he seems to have walked onto the wrong set? So what the heck is this creepy game?! Zombie dungeon: Zhou Cheng: “A thousand-year-old zombie comes back to life and starts killing people? I get it! It’s a Gurongi!” “Then behold my transformation!” Zombie: “??? What do you mean, a nuclear blast kick? Are you even playing fair?!” Impostor dungeon: Impostor: “Die! Everything you have will be mine!” Zhou Cheng: “You can turn into me? (He takes out his belt.) So, are you an Undead or an Orphnoch? Never mind, take my Rider Kick! Henshin!” Impostor: “?” Vampire dungeon: Vampire: “Now, receive the baptism of the blood clan!” Zhou Cheng: “What blood clan? That vampire bat of yours is hideous. Take a look at mine! Kiva, henshin!” Vampire: “Wait, why is his bloodline superior to mine?!” Everyone: “Seriously, how is he so strong? Who is he, anyway?” Zhou Cheng: “Me? I'm just a Kamen Rider passing through. Sure, I ended up in the wrong dungeon, but no matter. I'll fight all the same!”
