I thought everybody had figured out that the spatula part was the greatest weakness of the "infinite" string, since you most rapid hit multiattacks seem to be fairly simple to ex block, and if you bunker the spatula segment then kohaku has to not be attempting to drop a plant to be able to block it. Which makes the string not completely tight.
if it was as impossible as you make out to break it then nobody would ever get out of it, and there are plenty of fmaids vids where people consistently do. never said it wasn't a pretty strong string, but nero in said vid that was commented on didn't even really try a bunker.
(besides, you're just jealous. 4c nero ain't got shit on 5b)
