Now that’s something I would think odd. Since sword tenchi could hold Ryoko back in that fight with Ryoko and Tenchi, and it is the thing keeping Ryoko sealed, I do wonder how Ryoko would be able to break free herself
See now we’re just speculating. None of this was communicated through the anime which is the creators’ fault. I think it’s a bit silly to think she somehow over the course of 700 years gathered energy and was about to break free just a day before Tenchi stumbled into the cave. At any rate, it doesn’t make a difference to the show itself.
