(You encounter Sakuya, who seems to be from the past, reminiscing of an incident from before. It seems like she doesn’t know that she’s now in the present.)

You there, do you know the way to the Scarlet Devil Mansion? It should be expelling scarlet mist, so I'm sure you've seen it... What? That incident has finished? How strange. It shouldn't have finished until all of Gensokyo is dyed crimson. I'm Sakuya Izayoi, the head maid of the Scarlet Devil Mansion.
