- Description from Novelupdates

Follow Kairi Izumi—a quiet, eccentric, and somewhat conspicuous girl— who never felt like anything but an NPC in a story. Working behind the scenes, unnoticed by others had always been part of her daily life, dwelling with medicine and toxins.So, it's not surprising that she wasn't tad attractive according to others.That is, until one day... that guy, he confessed to me.Wait a minute—doesn't that mean I'm a heroine now? Hang on, how is that even possible? Me? Heroine? No way! I’m just a girl from a small village who likes to help others. I don’t particularly stand out, and compared to the other girls, I’m not even that attractive.And so, a question lingers, driving the unfolding of this dumbfounding narrative forward:Wait, what do you mean I got reincarnated to be a heroine?That's weird because usually a heroine is not strong let alone smart - they are usually dumb, cute and pretty. Definitely not me. I mean, how is that possible? Me? Heroine? No way!

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.

Every night, he prayed. To every god on Earth.“Please, transport me to a fantasy world when I wake up tomorrow.”And then one day, his prayers were answered.Just not in the way he had hoped for.
