Is there anyone who hasn't seen the manga for this anime?...

I really enjoyed the episode that came out last Tuesday. I'm a little confused about what happened with Iko at the end and everything she says. My favorite so far is Nene. I'd love for it to be Apollo, but it's almost impossible because I think it's Rikka, or at least that's what they imply. But going back to Iko, I think it's good that they're developing her relationship with the protagonist, resolving those issues and introducing other characters so that eventually they'll be the others.
