She woke up from a painful accident cradled in the arms of an unknown woman! When she saw her tiny and chubby hands, she realized that she was reborn as a baby with her past memories intact.
Guess the authorities up there will get a memo for letting me pass the reincarnation cycle like this *evil laugh*
But then she was declared retarded, she didn't cry like a normal child, she didn't act like a normal child and she would prefer to talk to animals instead of humans! Being a mere child with no power and an easily extinguishable life, she decided to go with the flow.
Okay, you want retard? I'll give you a retard! I'll be the most awesome, most venerable retard you'll ever see and my beasts will prove it to you. Just watch!
