U_U Ok... and I care, why? There are other Naruto forums I can go to. This is the internet. U_U
Amaterasu was stated to not die even when MS is not active. However, genjutsu don't stay active once the MS has been deactivated. When Hiruzen fought the Hokages... the genjutsu faded away, right? Hiruzen killing the Hokage is the same way as MS fading away - KA uses MS as the source of power... just like the Hokage uses himself for power.
But none of it applies to KA. What applies to something else doesn't neccesarily apply to KA. Do you understand how KA works btw?
