So, the thought is that my character used to be a princess of a country that got taken over and absorbed into another. You were a spy master and assassin that the royals ordered to protect and care for her until, she could live on her own safely. She was about two years old at the time. You accept the mission and take the role of her older brother. Timeskip to about eleven years and shd goes to school and you, you have become the leader of a Mafia or Yakuza and use them to protect her and rule over the neighborhood.
