I think its bcuz of the curse didnt they say its worst than death it prob has something so the person who drank it can kill itself （￣へ￣）
I think she have godess luck by her side, because she herself said in the first chapters that there was a chance of 0.1 or something of the poison don't killing the person but instead making them older or younger.
Oohh yeaahh they said that, thats a good point, so the curse is so powerful maybe more a devil power than a curse
That would be so cool! Because at this time I dont like the supposed to be a saint maiden main character, she’s more evil than good, I rather have ciel with the goddess blessing
So there’s something special with her that she can survive poisons like the visenna, i wonder what it is
