The Uchiha secret

[Anduril]

That would be idiotic ....

an EMS can be unlocked when one of the brothers has lost sight due to the over use of MS and his sibling has also developed MS of the same level...

Now while transplanting the other eye it is necessary that the other eye has still not lost its sight...

So basically its a transplant between one working and one non-working set of sharingan eyes...of two siblings.

That would be truly disturbing, half of the clan giving up their eyes. Who would decide who keeps or donates their eyes and wouldn't someone eventually rebel against this?
