Is Unlimited Void’s biggest weakness simply that everyone knows what it does?
I genuinely can't think of anyone who could beat Gojo if they went into the fight with absolutely zero information about his technique.
And I think Unlimited Void is a huge reason why.
Against an unknown Domain, figuring out what the sure-hit actually does before committing to a counter can be the smart move. Kashimo vs Hakari is a good example: once Kashimo understood that Hakari's sure-hit was simply transferring the rules of the Domain, he knew what he was dealing with.
But trying to do that against Unlimited Void is basically suicide.
Unlimited Void doesn't give you a rules explanation before the dangerous part starts. The information itself is the attack. By the time you've “learned” what the Domain does, you've already been hit by the thing you needed to prevent.
Which makes me wonder if one of Unlimited Void's biggest weaknesses is ironically just how famous Gojo is. His strongest opponents already know that this is one Domain you absolutely cannot afford to experience first and counter second.
