The addition of extra hands and fingers nicely keeps this from being a repeat of the previous Shigaraki battle with Erasure involved. There are plenty of smart and powerful heroes present, so I'm certain that they'll come up with something to at least stall him out. But the tension is very real. And yes, the robo-parts for Mirko shooting out to her is really cool. Horikoshi is great at coming up with fun support items, so I've started wondering what his original idea for Deku would've been like.
I'm really happy we get to see Gang Orca's aquarium. Not sure why since I don't even remember where it was referenced, but I'm happy to see it. Same with cameos from Sirius and Moonfish, wonder if Selkie will pop up as well.
Different translations seem to have a somewhat different interpretation about why Toga didn't activate Danger Sense. One is that her sense of love is so warped that it her expression of love (i.e. stabbing) doesn't register as an attack. Another is that she's just too far below Izuku's abilities so she doesn't register as a real threat to him. Not sure which one I prefer.
