I don’t get how charlotte can look so young even before she lost all that mana and become a kid again. She looks a lot younger than carsilion when carsilion is a disciple. I don’t get the ages of the character. Someone explain which is older? Ivan also looks young... jeffrey too.. Dan is half demon so maybe he ages differently so its understandable.
@Seracila in the first few chapters they already said Charlotte received a blessing from some spirit or something (it was a short scene), basically she is near immortal (not the same as invulnerable) and stopped aging physically after that blessing.
About her becoming a kid, that's the mystery we are reading about to find clues
