Not sure if you did it on purpose (bravo) or by accident (still bravo), but I was talking about this manga but I am happy you linked Pupa.
Thanks 😆
I remember a manga I liked very much.
It was about a brother trying to save his sister from becoming a monster, and his sister trying to remain human while saving her brother using monster powers.
It was a very endearing story and I hope to find it again one day.
