The real reason behind the scouting of am assassin like Regina seemed really mysterious to the count's family.
Even Rachel herself was shocked looking at the uncanny resemblance she had with the girl. They were around same age too, but since she was appointed by the count no one in his estate would dare to question him.
Regina was seventeen years old when she actually decided to work for the count. Maybe the bounty for the mission was a little more than what she actually expected, but still the overall mission was a fine play to look forward to.
She signed the contract for perhaps more than one reason. Dashin, the guild that she worked at as an assassin never allowed the permission to her to work for a corrupt count like Belford D'Azure, but since she had her own reason there was no stopping her.
