Apparently with "なます斬り" she's referring to a dish called kuai, in which fish is sliced thin. I tried translating the few pages that didn't have translations so now it's finished, even if it's a rather abrupt ending. I also took the liberty of removing the tag "series:myon_and_the_pink_demon" from the half of the pool that had it. It looks like such tags are not used any more in favour of pooling images instead.
I can't make sense of the remaining lines. I think the line pointing to Marisa in the top panel says 子煩脳, and that the one in the bottom panel says Marisaの連れる in reference to the little one it's pointing at.
I think some of the speech bubbles should be different. Given that EasyV has a lot more experience than me, I'll post my interpretations here rather than edit them in the case I'm wrong. Second to last page: "This strangeness really disappointed Marisa no ze!!" - "Don't disappoint Marisa any more no ze!!" "What is this something this stray is claiming?" - "The other stray is clamouring for something?" "It seems to be the nature of the stray Reimu's companion" - "It seems to be the stray Reimu's companion"
