Once again you are comparing it to things that are simply not on the same level. As well as Yata is still not been proven wrong.Just like Kishi said Edo Madara had no weaknesses?
Stop treating the databook as canon.
Funny because Itachi is still relevant. Unless next you're going to tell me Sasuke is dead? Lol What part of "all things become meaningless" is so hard to understand. The fact is Yata is a tool on another a level higher than anything else in this manga. It is not a hyperbole.Wasn't Kamui stated to be unblockable? Yeah, equal that out. The statements within the databook aren't meant to be taken literal, it's hype just like statements within the manga itself. Taking the Yata Mirror's hype seriously, is not only ridiculous, but it looks as if you're grasping for straws in an attempt to keep Itachi relevant.
