I don't really like how inconsistent the story, the MC was betrayed by her siblings before, and she will be hunted and tortured before killed by the demons if they found out that she is the grand saint
but she still using the saint powers and knowledge (experience) carelessly (enhancement, try to heal a little scratch, etc.) and keep acting suspiciously, she doesn't even try to seriously hide it (worst effort) :O... even the kingdom best investigator doesn't know anything about the girl while her brother carefreely blurting that she contracted black dragon and then most of the characters from the first plot (family, fabian) are forgotten and even keep introducing new characters for comedic relieve.
well, it's kinda fine since this manga focused on comedy, but don't expect serious plot or progress even from the serious back story (it seriously focused only in comedy)
it's not perfect but still fun to read.
