The world will eventually end, but civilization will never be silent.
On the seventh day after Hermann's death, Asia found a map of a port that did not exist on any map.
Following the last clue left by her teacher, she boarded a black ship sailing beyond the white mist, leaving the world she was familiar with for the first time.

Later, Asia realized that the map never recorded the land.
What it really records is proof that civilization once existed.
