In a village long forgotten by the rest of civilization held a dark tradition.
"Should a child of the devil be born, it must be taken away from its human womb, and punished for replacing the true child."
As it was an ancient rite, it was always followed by the villagers, no one finding it to be inhumane, only justice.
However, one year, it wasn't one demon child, but two. Twins, to be accurate. Fraternal twins. Shocked, as this had never happened in the thousands of years that this village has existed, they separated the twins between the mother and father, believing they held less evil as there were two.
The mother, holding many beliefs against the demon children since her brother had been killed by one who went on rampage, decided to punish the boy in the worst ways she could think of...
When he spoke while she was talking, his tongue was taken.
When he touched her, he was slapped or sometimes, even whipped.
When he woke up later than her, he was forced to stay awake the whole day.
Without a name or a reason for why he was punished so severely, he lived the same way for 9 years, until he was taken from his mother by the other villagers, not told why or where.
The father, on the other hand, had sympathy for the demon children, sad by how roughly they were treated, and decided to treat the girl nicely. Of course, he continued with the traditions of not giving her a name, but other than that he tried to treat her just like how he would've treated his own daughter.
However, just like the boy, the girl was taken away as well at the age of 9, the father giving her up reluctantly.
This is the story of the demon twins, and their fateful encounter with one another.
