World-class pharmacologist Kanji Yakutani awakens to find himself reincarnated in another world as Farma de Médicis. No longer able to pursue the cutting-edge drug research he did on Earth, he must adjust to life in this new world and in his new family.

Having discovered a variety of new abilities and learned of the poor availability of medicine in this new world, Farma begins testing what he can do with Substance Creation, Substance Elimination, and his Diagnostic Eye. If he can master the use of Divine Arts, as well as his special abilities, perhaps he can help the people of this world the way he longed to do in his previous life.

Farma's efforts to create a pharmacy for everyone, nobles and commoners alike, aren't achieving the desired results. But with some help and advice from family and friends, Farma might be able to turn things around.

Things are looking up in the Saint Fleuve Empire, with Farma's initiatives improving the overall health of the populace. However, word arrives of a mysterious new illness that threatens to sweep the nation. Farma rushes to prepare for this frightening scenario.
