Well, if the preview was any indication of things to come, Haruka (and this timespace) might need all the firepower they can muster. Even if it's a bunch delinquent knights from another dimension... Althought it's hard to see where the story is actually heading for. So far almost all fights have been bickering amongst the dragon knights. Maybe fighting against Shangrila is a purposeless thing to do anyway. It's also emphasized by the fact Noein is the only real Shangrila being. Dunno. This is like a story of Haruka finding herself, and everything happening around her is of secondary importance, and doesn't matter in the long run.

Edit: What I'm trying to say that this is a kind of philosophical story, or a long-winded chinese chess match between Noein and Haruka. Right now I don't think the actions of the others play that big a role; they only help Haruka to form her own opinions, reflect her actions, and seek the path she's going to tread.
