Izanagi + EMS
The EMS has eternal light, which means, no blindness from using EMS.
However, using jutsus like Izanagi, should still come at a great cost imo.
If you can just use Izanagi without consequences, that would mean you cant die.
1-So it should have a cooldown, like Shisui had with Koto Amatsukami or because of a chakra drain.
Meaning when you use Izanagi with your right/left eye, you cant do that again for x amount of time.
Meaning you cant use Izanagi for a while, after 2 times (both eyes).
This way, you can keep your eyesight as an EMS user, but it will not be insanely overpowered.
2-The other option could of course just be, that the eye you use it with, closes, even though you have EMS.
What do you think?
Which option do you like and why?
Or do you think it works differently and how?
