Parallel World Pharmacy

A brilliant pharmacologist, driven by the guilt of losing his little sister to a tumor that existing medicine couldn't save, works himself to death trying to develop better cancer treatments. He wakes up as Falma de Médicis, a 10-year-old noble's son in a medieval fantasy world where healthcare is basically a luxury good for the rich and everyone else just suffers. The twist: he's been blessed by the God of Medicine with the ability to create and destroy matter at a molecular level, which is a pretty handy skill when you're trying to reinvent an entire medical system from scratch. This 12-episode TV series follows Falma as he uses his past-life knowledge of modern pharmacology to develop affordable treatments and open a pharmacy that actually serves common people, butting heads with a society where the medical establishment gatekeeps everything. If you liked the "rebuilding civilization with science" angle of Dr. Stone or the way Ascendance of a Bookworm handles a reincarnated protagonist slowly reshaping a rigid class system, this hits a similar note but through a medical lens. The pacing is steady rather than action-heavy, think more problem-solving and ethical dilemmas than big fight scenes. Studio Diomedéa keeps the production clean and the world-building grounded enough that the medical concepts don't feel hand-wavy. It's a quieter isekai that actually has something specific on its mind, and that focus on healthcare accessibility gives it more substance than the premise might suggest.
