Unless this page explains something (which I doubt it is, because this is Marisa's speech), this is indeed the ending. Quite disappointed if you ask me. But based on previous events, we can roughly guess what fate the Marisa squad will be. The father's one eye is blinded and her body is molded, not only that, she has a cut hat; one child has lost their accessories and is bald, the other is too small. Lament your fate, Marisa, for having a deibu wife (but seriously thought, why did she just leave and don't do anything else, that thing kill her children, that's mean that thing is not a yukkuri anymore, but an unneasy thing, and yukkuri must get rid of all uneasy things).
That's just how Eisei draws their kos. :3 Eisei's yukkuri are cuddly and cute.
I think you misunderstood something, mate. Maricha is small even for a ko, maybe she's just a toddler, look at her sister, she's still small (and cute) but not that small, compared to her, Maricha is tiny.
"Mister Human... Please listen to my words noze
Marisa is already... dying nanoze
Therefore, at least let Marisa's cute, cute little ones
do "room-sharing" with Mister Human noze
They will definitely make Mister Human feel easy noze..."
