Kusuri Uri no Seijo: Enzai de Tsuihousareta Kusushi wa, Henkyou no Chi de Shiawase wo Tsukamu

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 a 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: MU
