“Oh Lord Lunareio, you are the only one who can save our world.”...My name is Rikuya Takatsuki, and I didn’t ask to be summoned to some fantasy world with my classmates. But there I was, expected to be a hero and protect the Kingdom from Realm Eaters, dimensional monsters chewing through reality.Apparently, all the races summoned forth heroes of legend, which was sort of a shocker to me since it wasn’t the cliché “slay the demon king” trope.Sounds cool, right? Wrong. While everyone else got flashy powers and legendary classes, I was slapped with the FFF Auto Hero class—no skills, no perks, and no respect.The kingdom handed me some pocket change and politely told me to scram.Fine by me. I was all set on enjoying the easy life in this new world anyways, when out of nowhere a bunch of cultists kidnapped me, claiming I’m their prophesied god or whatever.They gave me a mansion, unlimited snacks, and zero responsibilities, so of course, I played along.But then my so-called useless class kicked in. Turns out Auto Hero means my body hijacks itself whenever there’s danger, turning me into some kind of unstoppable killing machine. Efficient? Sure. Ethical? Not so much. Now everyone thinks I’m this terrifying cult leader who takes down monsters, corrupt kings, and anyone dumb enough to stand in my way.While my classmates enjoy their shiny hero lives, I’m here in the shadows, leading a cult, toppling kingdoms, and pretending I have some grand plan. The truth? I’m just winging it.I mean... what’s the worst that could happen?
