Oh yeah there's that other hero, heh he's going to rock Noboyuki's world for sure. Anyway yeah I think there's at enough detail in Rena's dreams for him to easily connect to her, I've even referenced her almost directly twice, at least to my memory, could've been more. 

Ok, sure might be time for them to finally start talking, might be Nonoyuki who starts talking unless his next dream does more to reveal its about himself.
