Synopsis
In his life-long obsession to develop new medicines to help people, Kanji Yakutani, a Japanese medical researcher, dies from overwork. To his immense surprise, he finds himself reborn in another world with a medieval culture, in which proper medical treatments are an affordable privilege to the wealthy only. In his new life as Farma de Médicis, he discovers that he has been granted a divine blessing from Panactheos, the God of Medicine. With his divine blessing and his retained knowledge of modern medicine, Farma decides to revolutionize the other world's medical advancements and make proper treatments affordable for the common folk. But as one medical emergency follows another, Farma also has to learn what it means to really live in his new life.

Characters

 * Farma de Médicis (ファルマ・ド・メディシス)
 * A 10-year-old boy who is the otherworldly reincarnation of Kanji Yakutani, a world-famous medical researcher at T University who created countless medical advances and medicines to counter any sickness. After losing his younger sister Chi to an incurable brain tumor during his childhood, Yakutani became obsessed with pharmaceutical research and development of new medicines, which he did exemplary. This drive caused him to die from heart attack due to overwork and fatigue at the age of 31, but he is reincarnated into a medieval world into the renowned de Médicis noble family in the San Fleuve Empire. When he awakens in his reincarnated self, he was told he was previously in a coma due to being struck by lightning and is now acting differently than how he used to be prior to the incident. The Divine Art bestowed upon him allows Farma to create water and, thanks to his knowledge in chemistry, other basic elements, and to perceive medical anomalies, but he was given Elementless ability, which is quite rare, unlike the original Farma who used only Water based spells and skills. He bears a scar on his shoulder as a visible sign of his blessing by Panactheos, and he no longer casts a shadow, which was solved when the Church's bishop gave him an artifact to produce a shadow, alongside the church's hidden staff that only usable by the person blessed and made Apostle by the Medicine God.

A brilliant pharmacist in his own right, he is, however, hobbled by the limitations of his world's medical knowledge.

 * Veron (ベロン)
 * The master of the Saint Fleuve Pharmaceutist Guild, the only institution in the empire for licensing pharmacists in the empire until Farma succeeds in winning Empress Elizabeth's favor. Mostly out of jealousy, he begins sabotaging Farma's efforts to open apothecaries for the common people, resorting to even outright vicious methods. During the Black Death incident, he and the other guild leaders stubbornly refuse to accept Farma's cures and therefore all die from the disease; this and the ineffectiveness of their traditional remedies causes the lower guild ranks to flock to Farma for assistance, which is readily given.
