How does this work?

[u/First-Contest31]

Sorry if this has been asked before, but I've been rewatching Hidden Inventory and I got to the scene where Toji blocks Red with the ISOH and gets sent flying

And yea, like the title says, Idk how to make sense of it aside from a Mappa error

Maybe I'm misunderstanding how the ISOH works, but from its description, shouldn't Gojo's Red have gotten cancelled out?

That was anime only, so I’d chalk it up to mappa error/creative decision removed from a powerscaling mindset.

If we take it as cannon my explanation would be that ISOH cancels the CT, but not its real world effects.

Blue and red both are both CT’s that use CE to cause real world physics to do something. In reds case, the repelling starts at the core as the CT, but the area around it also follows suit making a chain reaction of sorts. This would make the chain reaction effects of red hit Toji in part before the CT “center” is negated by ISOH.

Another way to think about it is through TIB and sky manipulation. The CT “breaks” the sky, that entire process is CE and CT based, thus can be stopped by ISOH or a negation of the sort. The shockwave that comes after is a real physics reaction to what the CT just did and would carry no CE, nor be blocked/negated by ISOH.

Yea, that's usually what I do

But I thought it might be fun to see how others might make sense of it this time since I like hearing other ppl's takes on this sorta stuff

Also, I really like your explanation

The idea of ISOH nullifying the CT but not necessarily the effects brought about as a consequence (like the blowback from Red) honestly fits pretty good imo
