Carn wakes up from a vivid dream where he spent a thousand years as a gargoyle, guarding a demon lord's tomb.In this dream, he possessed supernatural powers, including the ability to teleport and instantly kill anyone within range who broke eye contact with him. Heroes, saintesses, adventurers, all fell before him.When he returns to his normal life, things take a strange turn. Carn realizes he still has the gargoyle’s powers, and the world he has woken up to seems different.But adjusting to the new reality is not the real issue. Carn brings back something nobody in this world has imagined. Not only he imports his powers to this alternate Earth, but he also carries over his gargoyle instinct and his hobby. He loves snapping human necks.Whether it's ordinary humans, explorers, super soldiers, cyborgs, mutated beasts, monsters, or mysterious entities from other dimensions, Carn eagerly anticipates snapping their necks, one neck at a time...In secret, of course.

After everything that Zaroth had was stolen from him, he decided to live solely for his desires, morals be damned!Close to his death, he resurrects and tames a mythical dragon, who turns out to be a breathtaking woman.Learning that in order to explore her body, he must grow stronger so he doesn’t die during the act, Zaroth sets a clear goal for himself: to get stronger.“But I’m curious about something.”“Hm? What is it?” Luna asked, raising an eyebrow.“You said you judged me. How did you do that? Why was I worthy?”Luna’s smile darkened, her eyes glowing with a dangerous intensity.“Despite knowing you would die, you didn’t pray to the gods. On the contrary, you declared that you would kill every single one of them like the dogs they are. In my life, you’re the only one who’s ever made such a declaration, which is why I couldn’t leave you behind—someone who dares to share my dream.”
