^ Hmm... I believe you have to SEE the finger in order to fall in Ephemeral. In that case, I could see Guy being crazy enough by training himself to fight without opening his eyes at all.

Still, Gai is capable of dispelling genjutsu, when he broke out of A-ranked Temple of Nirvana Technique, so even he is hit by Ephemeral, he could dispell it with less effort than Naruto.
