Nami and Luffy are distant and the crew doesn't know why. Until they faced the marines, something unexpected happened...

(Y/n) a young boy, 17 years old, all alone, no name (yet), and no Idea why he exists, only that wherever he goes, death is not far behind by. What will happen when he meets Team RWBY? I don't own RWBY, the art, and weapons that will have the male reader.
