I think it's implied that by doing that skin thing, her filling will come out and Marisa will die. I mean Marisa was all "Even If I die doing this, I'll save the little one!" So we can say, in a way, this is a kill'em all scenario, just that Marisa will take a bit longer to die.
I dunno, she's not bleeding much at all. There's just some oozing but the main... uh... substance of her filling looks to be holding together pretty well.
I imagine she'll start to ooze quite a bit as she tries to move around.
I generally think that's why yukkuri are able to take so much damage that they're mutilated beyond recognition yet can still survive. Their past, for the most part, is still inside them and allows them to live, if only barely. Also kind of funny how their own thrashing around from the pain in this condition does more to kill them than the initial damage may have. It's kind of like stubbing your toe and then shaking your foot off and your bones all fall out.
Yu...And so. Once again Marisa fell into the abyss of despair.YAAAAAAAAAAAAAAAAAAAAAAAAAA~~~~~!! LITTLE ONE, WHY DID YOU BECOME LIKE THIS!
