I Shall Survive Using Potions! manga volume 3 features story by FUNA and art by Sukima.

Sometimes, you just can't help yourself. And if that means showing up kingdom after kingdom of nobles, well, it's even better! Or so Kaoru thinks, as she establishes herself as a divine messenger. But as word of her potions and abilities spread, so too does the threat of war and external involvement. As old faces return for another piece of the action and new threats emerge across the continent, can the Eyes of the Goddess keep their benefactor safe from harm?
