Figure of Hourai's Long Test of Courage

The Last Word of Fujiwara no Mokou, who has almost reached the end (a Touhou LW original). She reminisces about the time when the world was set free once again. Who would have thought that the moon was a giant memory bank? But there is no observer more adept and ancient than the moon, that has looked toward the Earth since time immemorial.

It is impossible to store information perfectly for all eternity without it eroding. But perhaps the people of the moon, who created the Hourai Elixir, know of a way to make it possible. If so, Mokou's lost friends might still be hidden within the moon.
