A slice-of-life story about a Guardian Witch and her adopted daughter.
3 Chapters and an extra/sequel has been translated. Don't know if there is more of it tho.

There's 7 parts ! https://www.pixiv.net/user/9817470/series/31181 ...so far

By and large it just makes me go "wtf is going on here?"

(I mean, sure, Witch picks up orphan kid to experiment on / poison, but somehow the kid develops a serious case of Stockholm Syndrome ... but the details later on are pretty sketchy ^^; )

I agree with Pyoro-san here, let me add, the art is stunningly amazing, but everything else is pretty controversial I didn't quite grasp the extent of their relationship, how they end up together, or how twisted someone can be from going to be a adoptive mother to a LOVER ... that's quite the step-up but yeah, I'll support the artist because of yuri

She's actually curing the girl, but she's tsundere. The girl's actions are a little...questionable, though.

By the way, you can support the author since she's releasing the books in English and Portuguese on pixiv booth this month. She also made a post about how pirating her works upsets her, and since she did make a effort to make it available for English speaking public, it would probably help to buy it if you can.

I don't think is controversial because this is a fantasy theme where one girl is a seemingly immortal (and caring in her own way) witch and the other is an orphan who already grew up into a beautiful girl and her feelings grow too.

But yeah! I love the initiative of Pixiv comic, there's another cute one with a "mole" girl in english too, I love pixiv comic because compared with many others it doesn't tell me "not available in your country"

Well, the love potion is kinda controversial, at least.

I’m really into the concept, and the art is amazing, sucks it seems like there’s no extra content
