Sarasa was originally a young woman with a weak constitution that forced her to carefully regulate her activities and lead to a life of working just to earn leave for immediate use to rest. After going to sleep one night, she was summoned by a goddess who revealed to her that she had been born on Earth by a mistake, as her body required mana to function properly which was the cause of her lethargy and that it would soon lead to her death. The goddess to right things sent her to a world rich in mana, but Sarasa awoke as a child at the front door of a cabin in the middle of nowhere surrounded by wolves.
