A letter has arrived, Mistress.

Mm, thank you for bringing it.

Oh ho...what a rare treat, it's from Reimu.

It appears to be a perfectly normal postcard, nothing out of the ordinary. However...

Heh...heh heh heh...Meiling...I have just noticed something amazing.

Normally, for stamps pasted onto this type of postcard, one licks the back of the stamp and affixes it, am I correct?

Hmm, well, I believe so.

In other words...

...there is a possibility that the sender, Reimu Hakurei, licked this stamp and attached it..

I feel as if I've caught the first glimpse in a while of your fearsomeness, Mistress...
