Drug Dealer Saint

My "off-the-beaten-path potion" saves everyone! The life reversal of an oppressed medicine doctor! Kuna, an incompetent and oppressed magician, is banished to the "Forest of Death" for a crime she did not commit. There, she meets a wolf named Roy, who leads her to the town of Wes, where the legend of a saint is passed down from generation to generation. Kuna is befriended by Luca, an adventurer who accidentally saves her life, and she discovers the joy of helping others as a medicine doctor, but what's that? Wasn't my potion a "miss," meaning that it had no effect? Meanwhile, in the village of Aco, where she was born and raised, something strange is happening. I'm an unaware genius medicine doctor, and I'll be happy here in exile! (Source: Kadokawa, translated)
