Isn't this Nitori's letter, from the outside world?

W-What did you say!?

Well well.

Reimu, Marisa Are you two okay? Well, if you two are reading this letter I'm sure you're fine. Man, guess I made some mistakes that this turned into such a mess, I'm really regretting it now. My bad.

But to be honest. I'd really love to take control of the game world in there from here and manually bring you two back. But the program has somehow ran out of control. It doesn't accept my orders anymore....

Haha, it's unusually commendable to see that Nitori reflect on her mistake.

I wonder.

If this keeps up, the worst that could happens is that your existences might be erased. But with the situation like this, there's really nothing I can do from here.

Wait a second, what does it mean "we might be erased"?

Doesn't this situation seem a little extreme...?

Ooh...

Something's making me nervous...

It still beats doing nothing, so try to achieve it if you can. The primary goal of the game is

The goal is?

Is?
