How long has Reimu been missing? For those of us that have characters that are friendly with youkai, we may have heard of Reimu, or Marisa, at least in passing from the youkai we've associated with, as those two had to be pretty infamous among youkai. What with the random beatings (and the saving the world, or course) all across gensokyo, and all.
Short and simple.
No one has heard of Reimu or Marisa.
No one has heard of or been to the Hakurei Shrine.
No one has mentioned the names Reimu or Marisa.
The last time Marisa was seen by a human was when she saved Takuma about ten years ago.
So consider Reimu to have fallen off the radar.
Note; Nanaya doesn't know of the shrine. When she passed by it she just thought it was an abandonned, rat and insect infested dump that could collapse at any moment. Also according to her profile her home is on the mountains behind Hakurei shrine. Idk about everyone else, but in my mind, I see The mountains containing the entrance to Makai as being behind the Shrine.
So therefore, I'm designating that mountain, or atleast a mountain next to it as where Nanaya's cave is. So Nanaya Does NOT live on Youkai Mountain. She cannot see the shrine from her cave either. Nor does she or Kasen visit the shrine. Kasen has not told her anything about the shrine or Reimu, and Nanaya has not approached the shrine at all. She has passed by it once while traveling through the forest. She was not close enough to see much of any details. All she saw was an abandonned and overgrown building that was being returned to nature.
Since I think I've made my points quite clear, That is all for now.
Oh, also, nagging me
will not give you more detailed answers. It'll just piss me off.
