I normally impersonate Byakuya Togami since I myself have no true identity. I don't have a name, family register, relatives, and anything that could link me with my true identity. In order to have my existence acknowledged, I took other people's data and learned it so I could be able to impersonate them flawlessly. I could impersonate the person in question's voice and personality perfectly. No one could tell the difference between me and the real person that I impersonated.
