With the exception of the attempt to use the investiture purple, both Yoshioka and Konoe have negative results, instead of making more chains, she is accidentally breaking the existing one, teleportation as such was already somewhat unstable in the previous areas, so this ended up not happening, rather she felt like her crystal had a different form
Jack's theory turns out to be more correct, it's not that the effects are opposite, it's more like if the actions they want to perform have to be the opposite, since their action made the chain stronger, canceling the almost breaking created by the witch
(That is, the controls are inverted instead of the effects)
The ice wall where Rex's sword was, start to break, they dont have much time before fall to the abyss
