Sir, do you agree that other countries call you the King of War?
I don't agree. I prefer people to call me a devil.
You think I started the war, no no, you are wrong.
My secret to survival is to never join a war, especially with yourself.
Moreover, my existence is to bring nuclear peace to the world, and our Umbrella is the light of mankind.
