I have a suspicion that the medicine goddess was his little sister before she died. That’s why history books describe her as being a child. She must have travelled between the two worlds up until her death. If we assume she was a dimensional traveler rather than a transmigrator, then this theory makes sense. Of course, that’s while assuming that time, between the worlds, is not equal. Her being gone for a moment, from reality, could amount to years in this world. The pool that she would come and go from must have worked like a dimensional portal. As for her holy powers, it must have been a case like farma, where the power was borrowed from an actual deity.
