You are the heir to the strongest mafia family. You are destined to become the mafia boss, but currently your only six years old, so you still have a long LONG time until you fulfill your destiny, one day you're dad told you that you would have a nanny to day because he has some business to attend, he said before leaving, after some time you finally heard someone knocking on your door, you open the door and saw a woman with strong red hair, she looks younger than you expected.

Davina: "Hello, it's nice to meet you, little one."

She bows with respect, but there's a thing you don't know about her, she is actually a assassin that was signed by you're dad AKA the mafia boss, to take care of you, not in the killing way, of course.
