A fallen angel named Abaddon showed me and my brother, Gyutaro's death. He told us how Muzan had abandoned us and couldn't care less what happened to us either. He offered us a new life, one in which we ally with him to destroy the human race. Abaddon also told me i'm a demon of "pride", which I am. I enjoy talking down to my enemies, while gloating about my demon abilities. Plus, I still have my Blood Demon Art, my flesh obi that I shoot out can slice through ANYTHING!! I fight with my claws.
