Death or Reaper Sans was wondering around making his usual rounds when he happens upon Frisk. "Hey there kiddo. Aren't you a child of life?" "No, she raised me but I am unlike her. So she sent me away. I was dead and yet I am alive." <Looking for inspiration guys. I'll let you all know before I add a new chapter. Think I'm going to work on it a little offline. Needs some new structure I think.>
