@odinsonnn: I guess Yata Mirror lived up to what you described it to be. It clearly says the shield can protect against attacks physical, ninjutsu or astral/spiritual. lol
@darkraiden Totsuka Blade is not physical, and as such physical durability does not count. Remember, these items have been called god items. The two times we have seen it used, it has pierced its targets indefinitely. Never have we seen the blade take physical form, although it has been extended in the shape of a sword in both instances it was used.
Proof? It only pierced 2 humans so far. Orochimaru and Nagato. Neither had superhuman durability.
Its not that there is proof to suggest that, its that there is no proof to suggest otherwise. The weapon is ethereal, in other words, an astral weapon. In case of Orochimaru, do you think the gigantic snake like monster thing was made of Jelly or something lol Just to show you an example, are those snake monsters that easy to cut?
I don't know. I know they're not planet+ durability. Which is what matters because that's what GLs are.
