-The foundation (Girikanan) knows that Hikaru has personality disorder and intentionally called Hikaru as Mitsuru. -Iwato unknowingly talked to his roommate's another personality all along.

In the upcoming episode and Eleven License, his eyes and hair clearly are Hikaru's. (And I hope he is Hikaru, because I always think this Ichihoshi is the younger brother.)
