Darkness is coming, and crisis is everywhere. In this long dark and desperate night, do you want to see a bonfire with warm words? We are that light.

We don’t want to be the little bully who guards one-third of an acre and eats canned food.

We don’t want to drive the harem on a great escape from east to west.

We don’t want to be a bunch of rats guarding rancid cheese in the gutter.

We don’t want to see the panic on your faces and the desperation in your screams.

So we stand up, fight for ourselves, fight for you, fight for humanity!

As long as we are here, the flames of war will never be extinguished.

We light a warm bonfire in the dark night, and watch the dawn with the brilliance of life.

We are the shield of the earth, the patron saint of mankind!
