The All-Purpose Apothecary Isn’t Plotting Revenge

The protagonist, who worked as a pharmacist in Japan, is reincarnated as Marianna, the royal palace's exclusive pharmacist. However, the medical situation in her new home is sloppy, and as a result of acting for the patients, she incurs the wrath of her superiors and is fired from the royal palace. "I'll do it myself," Marianna says with renewed determination, and moves to the Dianthus territory. Together with a handsome duke who for some reason takes a liking to Marianna and won't let her go, and her cute, fluffy spirit companion, she uses her cheat-level compounding skills and pharmaceutical knowledge to develop new drugs and improve the medical system!
