Overview

An alluring young student of the medical arts…
A golden kingdom ravaged by an unknown disease…
And the secrets of alchemy that could consume everything…
Vita, an extraordinarily youthful and gifted plague doctor, struggles to find a cure for the strange infection destroying her home.

Having spent her entire life in serious studies, she has no time for relationships or frivolous activities…but for a young, elegant beauty, there are monsters more malicious than viruses…​

Miscellaneous
This update introduces a classic monster: the Mimic. (Somewhere in Nightshade Caves)
The CG composition uses a two-stage format, showing the progression from just being grabbed to being dragged into the chest.
The drawing of a new map is also currently underway. The next area will return to a monster-themed zone, please look forward to it.

v0.41.0 Beta

Added “Slowgrow”, a special medicine to extend the pregnancy cycle.

Miscellaneous
The so-called “Security Patch” allows players to fully experience the game. Without this patch, only partial content may be accessible. Friends who have supported me in previous works will probably understand what this is. I can’t say much, but it’s the only way to protect the project from censors.

Hint
Accessing the new map requires completing certain prerequisites. After Vita rescues all four women, she will discover Sapphyra is missing from the town and find a note left in her place. After reading the note and speaking with Baneberis, Protya, and the traveler in town, the new map will become accessible.

A note from DarkmoonTranslations, co-writer and translator.
Hello! I’ve just done a total rewrite of all lines and translations so far!
Some of the earlier versions had some grammatical errors and untranslated parts, but now everything should be smoother from this point forward.
For example, our slightly pretentious heroine has always had a bit of a French accent as part of this setting (“La Vitalis”); hopefully it should be a little clearer now.
