"The strength to protect, huh? But what are you really protecting? A tomorrow that will only end up being worse than today? You're as strong as ever. But... It's too late! There's no hope for you now! Go down to the lowest floor, and see for yourself!" The heroes went down there.

If that were possible, all wars would have ended long ago! I can only see one future! One where selfish, foolish humans think about nothing other than themselves and steal more and more from one another... It's a tragic future!"
