There is something I am curious about...how would being an ajin effect their allergies (such as peanuts, or pollen) or substance intolerance (such as lactose or alcohol)? Also if the ajin has asthma and that ajin dies, will they still have asthma?
This is one of those interesting grey areas, only for once it’s actually not based on what little we know about ajin.
Basically, if it’s an allergy developed over the course of your life (for example, I’m lactose intolerant, but I wasn’t for most of my life), that would be reset back to how it was before. If it was something they were born with, they’d get stuck with it.
So like, if they had asthma from smoke inhalation, they’d no longer have asthma. However, if they had it from childhood, they’d probably still have it unfortunately.
I’m sure someone more medically minded could weigh in more specifically though.
