The story about the factory's sudden extermination and the bond and love of a family that stood up against their inevitable destined destruction.
I really like the Reimu-type's "Evacuate into mommy's mouth okay!", so this is a story with that element.
...No matter how I see it, I always think that the inside of Reimu's mouth is far too large, but don't mind the details noze!
