Yata Mirror The invincible godly mirror, really ?

[Waltz]

However, that's speculation and nothing more.​

 

[Bogard]

Yata mirror already showed the incapacity to repel light since it's first introduction. The hyperbole was already contradicted

 

[~Ethereal~]

Hmm.... what are the feats again?!

 

[Dark Artist]

if you read the manga
you will know that itachi doesn't has a kill intention

he doesn't want to kill kabuto

why should he use his full power on someone he doesn't want to kill ?
