then how would tobi replace his eye if he cant open it??No dear boy,Izanagi can only be used once;the eye that uses it closes permanently.Its duration varies from user to use.
Even if it's still closed, you can still remove the eye. The eye that used Izanagi was the eye that closes, so when replaced that eye doesn't close, because it hasn't used Izanagi.then how would tobi replace his eye if he cant open it??
the doesn't shut it just goes blind, look at itachi's same thingthen how would tobi replace his eye if he cant open it??
