Corporate worker Reiji wakes up in another world with no combat skills to speak of, only a Medicine Maker ability that lets him brew unusually powerful potions. He sets up a small drugstore in a rural village, and word of his remedies spreads fast enough to turn the business into a real success as he settles into life alongside coworkers Noela and Mina. Reiji's daily rounds handle problems as ordinary as vision trouble and as strange as a fire-breathing dragon with a persistent cough.
