How very interesting.

I would certainly be interested to see where this Fairy Circle idea takes you. Would you mind keeping me informed on what you find? I'm willing to help, if you only ask.

[Because Yukari's been trying to figure out the Door, too. But he hasn't had much luck finding information on that or the deities. Congratulations, Russia, you've piqued Yukari's interest just enough to be willing to work with you.]
