I find that Rahxephon Episode 26 a little confusing...... Cos...at the ending Haruka was with itsuki kisaragi???
At the end i was wondering if Itsuki Kisaragi is Ayato older self....
That isn't Itsuki (though Ayato does look a lot like him then, makes you wonder)
Basically, at the end, Ayato rewrote the world to be a happier place for himself (he's aged correctly without the Tokyo Jupiter time difference),Haruka and even Quon.
