I'm going to kill everyone who calls me Hill.

I, the Valkyrie Xi'er Fuleai, am a master of mowing the abyss, a weak, cute and considerate little butterfly, the owner of the Death Book, and the official licensee of the back seat of the flat-back motorcycle. I want to say here that my name is Xi'er! Those who call me Xi'er, wait for me. When I find the way home, I will kill you all!
(Everyone: OK Hill, no problem Hill.)
