Minato Atami is summoned to another world with the ability to create elixirs, the ultimate healing potions. However, the potions he makes are nothing but plain water to anyone who drinks them. Branded a 'useless reincarnator', he is promptly kicked out of the temple. As someone who has always dreamed of another world, Minato instead finds himself free to do as he pleases, so he decides to enjoy this new world! Then, after suffering a near-fatal injury, he realizes his true ability. That's right. His ability is to create absolutely cheat-like potions that have no effect whatsoever on others, but work only on himself! And there's no limit to how many he can make!! Minato fights endlessly and continues leveling up, eventually becoming an unstoppable force in another world!!
