>Are we aware of any such rules or customs there?
>To the best of your knowledge, the Dragon shrine has only one rule that the other shrines do not share, and that is no footwear of any kind, outside of socks, may be worn while within the shrine.
>That's the only official rule, anyway. It does have one unofficial rule as well that's unique to that shrine, and that's 'Try not to let Tenshi get too full of herself.' Or so Reimu has told you. The head miko of the Dragon shrine, one Tenshi Hinanai, has a fair sized ego, and often has a spot of trouble reigning it in when the Hakurei heir is not present. Reimu encourages people to either ignore Tenshi when she gets on herself, or deflate her ego a little. You yourself find this a little unkind, though you can sort of see her point. You've met Tenshi yourself, and Reimu is very right in her description of Tenshi's level of pride. She could be very overbearing, but she's not a bad person. Rough around the edges, definitely, but not bad.
>Knowing Rin as you do, she could very well take Tenshi's bluntness the wrong way. You have a feeling that your kasha and Tenshi wouldn't mix all that well, should Tenshi cross your path at the shrine.
