It's a spiritual item.This is what people forget... the item is legendary. It's not insane or unbelievable for it to block any attack because it's a godly item, it's legendary.
I don't see why not. It can block any attack, renders any attack useless, changes any of its physical attributes which includes size (so it can block from behind and below as well)
Until this is contradicted, the Yata mirror will remain impenetrable.
till its proven if i can be defeated it remains unbeatable
we all know Susano itself is not very strong unless we're talking about Perfect Susano which has really strong armor.
^notice the back and sides of Susano unprotected by Yata Mirror, which are clear open spots to lay a hit. xd
Concerning the yata hype there are some questions that need to be ask
1- How does it actually change its attributes according to an attack? Is it automatic? Cuz i don't think the shield possess eyes or some sort of detector to notify the opponent attack in question and act accordingly? Or does it?
2- If the shield in question doesn't change it's properties on its own(meaning it doesn't have a sort of detector to notify the opponent attack first), does it mean it's the user of the weapon who changes its properties manually?
If it's the case, does it mean that if the user himself fails to analyse an attack in time or doesn't change the properties in time according to the opponent attack, would it fail to protect him against said attack?
It does it yes, but the means to do it is important to possibly notify the mechanism of the shield because it's hype doesn't clearly gives us a hint concerning its mechanism. If it does via direct physical contact with the opponent attack for example(the most likely), then this following questionWhat was said and shown by this supernatural item, makes me suppose it can indeed repel anything what directly hits the shield.
@Bogard, the shield makes it by itself, Itachi can't determine the exact properties of an attack. The databook also refers to the shield to be the one changing its properties. It doesn't say that the wielder changes the properties of the shield to repel the attack, but that the shield does it.
Don't try to go by a logical way, asking how it's going to react at the attack by itself. This is a point where one shouldn't search for a logical answer in a Manga. The shield simply does it.
