NA Localization:
The history of humans ended along with the planet's life.
The ideal king was defeated and had fallen into a slumber, sinking into a thousand year languor. Survival was under the guise of stability and management, but the future was uncertain. The people had forgotten their own meaning and purpose.
That was the reward given to humanity.
In the past, he would have accepted this end, believing that it may have been a lonely end, but a comfortable one.
But the ideal king was already buried.
By learning what defeat was, he gained the chance to stand back up. Even with his body rotted away and accepting the fact that his once envisioned ideal would not be possible, the king headed out into the deadly battle.
He does so to lead the people...to ask the people once again what the meaning of living even is.
Fan Translation:
With the life of the stars, human history is over.
The ideal king was torn down, fell into a fort, and sank to millennial malaise.
The survival of the name of stability and management can not grasp the future.
People forgot their meaning in the first place.
It is a reward given to humanity.
It is a sad but modest end,
He would have accepted it once.
--- But, the ideal king is already covered with the earth.
I knew the defeat but I got a chance to stand up late.
The body has fallen, and the dream you once dreamed of can not be achieved
While accepting, the king came to a lethal battle.
To lead people.
The definition of "live" once more,
To ask people.
