"The champignon witch" is about an apparently ageless witch living in a dark forest with some familiars, she has to avoid contact to other people as her breath as well as skin contact is toxic. Her name is Luna, and she makes medicine for a living, which she sells every three months to a pharmacy in town. Her life changes when she watches a young couple on one of those trips and can't stop thinking about the young man. So there finally was a translation of the first volume (unfortunately not in English, but German and as far as I know, French as well), available. Ipicked it up as the anime should come out next year. Overall, this first volume sets up the scenery and introduces us to Luna. It's drawn very cute although not all themes of the story are just pure cutesy, people avoid Luna due to her toxicity and she has some special magic tricks which I won't describe for spoiler reasons.
Her being a "champignon witch" was what had piqued my interest, the "special magic" is new and interesting (to me) and I hope to see more in further volumes. There are informational pages explaining the house, her clothing, her surroundings and more, which might be off-putting for those who only want "show don't tell". I give it 9/10 for some novel aspects and the aesthetics.

PS: This is my first review ever, so please be kind ;)
