Have you been looked at by a healing esper or medical professional yet? Are you unsure of where you should be going and who should be in charge of making you be better? Are you likely to go wandering into mysterious healing circles without knowing what might happen inside them?
Baek Ji-woo will fix that!
This is not optional. All who are even mildly confused about what is wrong with them will submit to Ji-woo's tender organizational ministrations.
(She does, also, need to swing by and do some lung damage clean up after Airmed, and sometimes occasionally does some quick minor bone setting for Aumento, but, you know. Primarily it's using her ability to know just what the fuck is going on in the human body, without much towards meddling.)
