Correction; "Reimu!, little ones!, it looks like mr.human has gone somewhere else!" ---> she didn't recognize miss' feet and it was dark. "Now is the chance to get inside mr.kotatsu" "Yufufu even if little ones don't rush mr.kotatsu won't be gone away"
Also; it looks like they were going to claim/make 'home declaration' while miss is 'away'. Rightfully owning mr.kotatsu. ---> see 2 post previous.
So on top of claiming that kotatsus just grow on their own, this Marisa (and possibly the rest of her family) don't even recognize legs as being part of the human.
I know I shouldn't be surprised by the backwards workings of the yukkuri mind, but I am.
