For example, did you ever "meet yourself," REIMU?

In that case, I might have. Just the one time, during Tenshi's incident...

Who are you?

... is what I unintentionally asked.

The dominant hand of the Reimu you met was opposite to yours, correct?

That's the exception, a mirror world.

Hmm-hmmm... Then, I completely have no clue.

But Reimu met with you.

In other words, paradoxically, even when you came to the past, it's nothing special! ... The offertory goes without saying.
