Great speculation, but one critique would be your use of science to describe lightning in a shonen manga -__-. Trust me it is very menial to include it, all you needed to say in the end was that the Sharingan/Raikiri combo is enough to counter Kirin.

That being said this only leaves one person who can actually pull off this specific counter, Kakashi. Something could be said about the Raikage, and also Naruto is probably a given.

Good thread nevertheless.
