Isekai de Ore wa Ero Keiei no Top ni Naru!

After dying in an accident in modern-day Japan, the protagonist is reincarnated as Kurt Lamelz, the youngest son of a noble family in another world. Dreaming of becoming the strongest in this new world, he’s devastated when the skill granted to him by the gods upon adulthood turns out to be “Prank Magic”—a seemingly useless ability. Shunned by his family and exiled to a remote area, he’s eventually abandoned altogether. Realizing he’ll only continue to fall further into ruin, the protagonist decides to use his modern knowledge to create and sell things that don’t exist in this world. Taking advantage of his single life back in Japan, he focuses on the erotic goods he’d stockpiled and starts selling them like crazy… aiming to become the greatest merchant in the world. And so begins a tale of rising from the bottom!.. [Translated from dlsite]
