Parallel World Pharmacy

Renowned medical researcher Kanji Yakutani has carried the grief of losing his younger sister to a tumor, a tragedy made worse by the limits of available treatment. Determined to change that, he devotes his life to drug development—until relentless overwork claims him at just 31. Instead of an ending, he awakens in a new world.

Reborn as 10-year-old Falma de Médicis, heir to a respected medical family in the Sain Fleuve Empire, he bears a divine blessing that grants him an unusual art: with an understanding of chemical properties, he can create substances and even diminish them. As Falma studies local pharmacology, he finds medicine trapped in an era of primitive practice—and reserved as a privilege of the nobility. Armed with modern knowledge and his newfound power, he sets out to bring proper care to everyone, regardless of status.
