You loss your light if u strain your ms like itachi and sasuke did, but the thing is that both there light where almost gone and now sasuke's back (no need for details)
My question here is that what if am loss the light in my sharingan(not sayin I have one) and I transplant the right one into the left,would that give mi ems and the light back seen as I combined two ms......
I want to know what you think
