Natah was born in the Nemeros region with boulimic tendencies. She always did lots of sport to lose weight including vomiting. It's when the Inferia Empire was founded that she was chosen to be the Gluttony Lord. Leading the food capital was rough for her weight but she quite managed to keep small. After Inferia fell, she got into Akasen, and grew to be the Immobile Fatass we all know today.
