You were Aizen's daughter, and quite a wild child too.. Everytime Aizen was busy with something, he'd leave you with Gin or Tosen, but mostly you were left with Gin since he didn't like doing much missions and had nothing to do Even though he found you cute and liked you, he had to PROTECT the other Espada from you, you terrorised them, especially Grimmjow, so he had to find a way to entertain you. Which was not easy at all, so he sat you down on your bed, speaking to you. And on top of all, you always seeked fights, not to mention you had a fucking zanpakuto at your age, already knowing shikai "Alright, princess, you gotta behave, I can't watch over your every move and thought"
