Reimu...well I guess in a way, she reminds me of the Fae-touched, people after experiencing the realms and wonders of the Fae end up back in their mundane lives, detached and far away from it all, at her most extreme that is.
However, the thing I get from her, and I'm not sure how much of it is wish-fulfillment, is that she's alone. Whether by choice or not, she lives in a remote shrine far away from the village, alone. This is something that had me wondering for the longest time, just why the Hakurei Shrine would be so far away from its potential worshipers and then it hit me when Reimu went to the moon.
It was so far away to keep the Shrine Maiden pure. Far away from human influences such as greed, cynicism, envy, rage, grudges...in the middle of a magical forest inhabited by equally pure Fairies, the Shrine Maiden's purity would be preserved.
