Parallel World Pharmacy
Kanji Yakutani, a pharmacological researcher in modern-day Japan, is reincarnated as Falma de Médicis, the son of the de Médicis family, a family of court pharmacists. Falma despairs at the medical science in this world, which is rife with incorrect treatments, and spells and charms that cannot be called medicine. Thus, he combines his modern pharmacology skills from his previous life with cheats such as Substance Creation and Substance Erasure from this parallel world, and makes full use of the divine arts to combat all kinds of illnesses. In order to provide the people with truly effective remedies, he opens the Parallel World Pharmacy.
