I am not human; I am shinigami. My duty is to protect humanity from non-human threats while maintaining the balance. This place, the creatures (including the staff) are threatening such balance, placing humans in mortal peril. It is my duty to prevent them from accomplishing their goals by any and all means necessary.

I know they are not human because I have the ability to see the souls of those who possess them. Humans possess souls. The staff, the creatures at night? They do not have souls. They are not human. I don't expect you or any other human to believe me, much less understand, but I do expect you to do what you have to in order to survive. Live.
