How odd. She has all this medical knowledge. We know she graduated from college to have a lazy and steady life. Becoming a nurse much less a doctor would mean a lot more work on her plate. Meaning that she never aimed to have a foot in the medical field. Is the Japanese curriculum so extensive that it includes so much medical education that she can so easily put into practice? Yes, it's magic, but the human body is so complicated that things are strategically twisted around each other and many parts look the same.
Also, for being such a lazy person, she's really taking in her Mary Sue halo and helping anyone who pounds at her door without a care. You show that you can think for yourself but your actions show otherwise. You somehow graduated college by probably not helping everyone along the way or you would look waaay more tired and stressed. So far this isn't very realistic.
With that said, thank you translator for taking the time to share this with us.
