Actually, I'm afraid that in this particular game if the lynchee is killed by any means other than lynching, the lyncher loses, although apparently they can still win by convincing the town to lynch a dead body. How would I know this? I am the lyncher!
And dd or kd told me that I can still win if we somehow lynch Ultros, which means either we can lynch a dead person, someone has a resurrection role, or Ultros's death was faked.
