There once was a young girl, rescued some 200 years ago from a Labyrinth.
However, that girl lost all her memory and emotions.
Her identity was unknown, but from appearance her race could be determined.
Thus, that girl was dropped off at that race's village and began her life there.
The villagers happily welcomed that girl.
That girl never regained her memories.
But a few years later, emotions did return to her.
Soon that bright and cheerful girl fell for a boy of the village, and they became lovers.
Soon they married, but from then a strange problem appeared.
Her sexual appetite grew and grew.
Every night she craved him.
The race that girl belonged to lacks a strong sexual appetite.
Inferior to human or goblins.
Because of that, the boy often felt troubled, but still they lived a quiet life.
Soon afterwards, that girl's body began to change.
Starting from her first time with a boy, every time of the month, she gave birth to something.
A magical crystal.
A small and round magical crystal.
Containing enormous magic power, it could be sold for a high price.
With her husband they discussed it.
Although it made him slightly uncomfortable, nevertheless he accepted her.
Afterwards, the boy sold the magical crystals in the city.
The enormous sums blinded him... But it wasn't his fault, so don't blame the boy.
They were not particularly wealthy, nor did the girl work.
At least, the boy did not treat that girl as a golden goose.
They lived happily together.
It happened 5 years later.
The boy died.
He was murdered.
Carrying valuables so regularly, he was marked by human bandits, and attacked, losing both life and money.
The boy died, and that girl became a widow.
Ten days after his death.
That girl lost control of herself and attacked another boy in the village.
She knew she shouldn't, yet she did.
But the target didn't really mind, so the matter rests.
Ten days passed.
That girl attacked another boy.
Another ten days, then another.
That girl went wild, her actions exposed, and was finally caught by the other girls of the village.
Thus she was cast out of the village.
Thereafter, she lived as a prostitute, a slave, and finally an adventurer, and even now she wanders the world.
