[@The World]Honestly? I don't mind if you just make it about as instant for both extension and retraction as, like, an extendable baton and a tape measure. It'll just take longer to extend or shorten it to a length that isn't the shortest or the longest. Only thing you'll need to be aware of is that it'd be 'easy' for others who grab the weapon to pull/hold onto it too.

[@BrokenPromise] I don't need finer movements if it's just a terrain-grabber, so ye, no.

[@OwO]Tug o War against small children turning into a stalemate because everyone has the same physical stats in Esper mode. Basically sounds fine though. I personally think it might be a bit weird visually to like, attack the chain but pop open the manacle instead, so maybe just say something like 'the manacle could be forced open by an E rank attack' rather than go on about 'attacking the chain'.
