Hmmm. I'm guessing greedy merchants trying to take MC as a pet and sell her. Capturing "divine beasts" and selling them as pets has been a cliche in some fantasy mangas.
I am only guessing, but I'm gonna bet the dudes on the last page are from the local medical association coming to "explain" how our heroine's alternative treatment is cutting into their action. Kind of like what happens in real life. 😑
I like Kumo's cure for cancer. Just cut it out knowing you're going to ruin the organ as you do it, but it's okay, you can just cast healing magic after.
