"Every two months when the full moon arrives, the energy in 'The Mirror Beyond the Clouds' becomes so saturated that it can no longer be contained, leaking out. The black mirror surface on this side will randomly reflect a location. And the other side of the mirror, Tsukumono Village, will overlap with that random location. The overlap lasts for about half an hour."
"God, the residents of Tsukumono Village are mostly harmless smaller youkai. However, when Tsukumono Village overlaps with some dangerous place, we Tsukumogami are forced to battle with dangerously mad monsters. In the past six months, we've experienced two spatial overlaps, and a lot of Tsukumogami were destroyed by the monsters, not even the God Artisan could save them..."
The three musical instrument Tsukumogami took turns speaking slowly, all looking very depressed.
In the afternoon, these elders filled the room with music, creating quite a lively atmosphere.
