I'm usually against the whole stereotypical childhood friend romance thing but I'd be happy with a Ikki x Ringo because they weren't "home free, but hiding their feelings/unable to express" the whole time, Ringo had a huge wall stopping her from being able to open up. And they've worked it out with a revolutionairy battle for the characters (mainly Ikki).
I'm wondering what happened with Akito and Aeon clock when Ikki ran for it because I don't remember seeing Akito at Kazu's house :O

Kururu reminds me of Lacus from GS and how she pretty much took the lead role later into the story. So that's who I'm rooting for.
Ikki always treated Ringo like a sister, and although she feels otherwise he never had any other feelings for her. Kururu on the other hand has been bonding with Ikki in a much more interpersonal level.
Duh ringo still has a chance & here is why:
1. she loves him & she showed it
2. she is one of the two girls that Ikki calls by there name without adding san or sama.
