Synopsis

After losing his little sister to an incurable disease, world-famous medical researcher Kanji Yakutani gave it his all to cure patients by dedicating his life to inventing new medicines. After working himself to death at the age of 31, the former pharmacist wakes up as a 10-year-old child whose body has been struck by lightning. He discovers that he has been reincarnated into a medieval world as Falma, a child of the respected De Médicis family.

In a world where divine arts—magic granted through blessings from guardian deities—exist, Falma realizes that his body is host to the guardian deity of medicine. The boy has been granted the mythical divine arts of creation and reduction as well as the ability to instantly diagnose illnesses in people's bodies.

He soon discovers the terrible state of medicine in this world: only nobles are able to afford medical care, which is ineffective at best and detrimental at worst. Using modern knowledge and his divine powers, Falma gradually makes a name for himself as a pharmacist despite his young age, even earning the recognition of the imperial court. When he finally acquires a proper pharmacy of his own, he sets out to pursue his goal of improving healthcare in the San Fleuve Empire and making it accessible to all.

What happens when your little sister dies from an "incurable" disease? You dedicate your life to studying medicine.. Then die from overworking yourself.

Story: 7
The story is pretty well written, being one of the better isekai mangas i've read. It starts out by showing Yakutani Kanji's workplace which he seems to never get a break from, causing him to develope extreme fatigue which he eventually dies from; New world here we come!

Art: 7
The art is pretty good, some parts i've felt it was drawn poorly but overall there isn't really anything to say about it.

Characters: 6
The characters are average at best, no one really stands out ...

So to start off I Don't read much 'slice of life' type manga but i did enjoy this one. When the MC goes to diagnose people and treat them he gives detailed descriptions on what the disease/illness is and how to treat it medically.

Also seeing how in this world the medical field is basically like the middle ages makes me really appreciate how medicine has really advanced since then.
The Art style ...

While there's not much difference between the anime and the manga, the manga definitely gets across the "This person has a ridiculous amount of knowledge and can think in graphs" style that the character really needs to sell the Pharmacist fantasy

Story and character wise it's really good, character motivations are solid and there's very little "win button" resolution to things when it comes to treatment. It leans hard on the idea of the best treatments taking time and not being a miracle cure all, which I definitely like, makes it feel far more grounded.

If I had a complaint it'd be the ...
