An Idiot in the Stone Age

Masaru Sato is a twenty-three-year-old engineer whose luck is so spectacularly bad that getting fired and stabbed in an alleyway wasn't even the worst part of his Monday. After accidentally insulting the flat-chested goddess responsible for his reincarnation, he is dumped alone into a brutal, prehistoric world without a single magic cheat skill. Armed with nothing but perfect memory recall and an obsession with Bronze Age archaeology, Masaru must use logic, science, and a little bit of friction to survive. But when a simple campfire convinces a tribe of beautiful, overprotective elves that he is a literal god, Masaru realizes his modern knowledge might just be more dangerous than the wilderness itself.
