To be honest when I saw this I was wondering how he didn't pulverize his hand since I don't think the yukkuri could have absorbed so much of that blast and considering he broke his fucking wall he had to have done some damage.
I'm also confused what happened towards the end. So he killed the Marisa and the Alice, but kept the Komarisa?
He didn't pulverize his hand because the universe hates yukkuris, not humans. And honestly, you don't think something could have happened, but from discussions in the past it seems things that you don't think are possible with yukkuris are possible (and the other way round).
Ever heard of Manga Fight Logic? well this is it, a human wtihout some level of unnatural power shouldn't be able to crack the floor while stomping on an averagely strong soil, even less should be able to crack a wall. Yet this mister bracks both.
And in those stories, those "cracking" the enviroment will never break their limbs out of that logic, it's beyond the point. And as Tea said, the yukkuri world seems more focused on screwing on the yukkuris than on the humans.
I even have this crazy theory that as part of that, humans get a massive power boost as a counter "belief" effect of the yukkuris delusional views of thinking they are strong and can beat humans, which leads to that world to just make humans stronger and stronger, to spite on them.
Marisa KILLED Alice by raping her to death, Mister Saw this and beat the crap of Marisa until it was death for sure, in the end he only had komarisa left, which is a tearjerker considering that now anon will have to explain poor lil komarisa how her adopted mommy got murdered and raped by some, from anon's POV, random stray.
It is because humans are super-powered in whatever universe that this story is set in. There was already a humanoid lion that can explode donuts and a ninja Anon...
Man that ninja anon was so out of nowhere, at least that Lion Doughnut guy made sense because he was a cameo from another story, but the ninja Anon was lol, so out of nowhere.
Agree with the manga/anime-physics there. Anyone sufficiently angry can crack walls and break concrete floors. Add that with yukkuris and well.... you get a ton of abuse out of them.
