Either Marisa is being tsundere or she's arguing with the strip's title. Possibly both.

It's odd to see her in the strip, she only appeared once before?

EDIT after translation : Oh,she was in tsundere mode.Nah we believe you Marisa,you're totally not going there. :3

The bigger question now: who is she talking to, the 4th wall or someone unseen?

My guess, she is talking to Aya.

Sounds like she's rehearsing her lines in case she meets someone else there.

Sounds about right, either that or the 4th wall just got annihilated.

I think the 4th wall got shattered. The artist seems to be enjoying messing with the flow of things as of late.

So in Nanaroku's version, Marisa tagged along with a Kappa during Subterranean Animism.

Alternatively, camera pulls back and Reimu just says "if you say so."

Knowing Marisa, it's probably at least the second one.

Alice got a really bad influence on you Marisa.
