-- Again, I believe it is neccessary in order for Souchirou to mature from being the "brat" that he is. Maya's presence made Souchirou aware of the oppostie sex(remember how Chiaki, Bob's girlfriend, teases Souchirou for being unexperienced when it comes to women). Currently, she inspires and drives Nagi to a point so that he might be able to grow fully into a warrior and a man.
2. Was his "love" that superfical?
-- It was honest, and innocent as well. Being "unexperienced" as he is, he doesn't really know what his feelings are. Is it admiration? Is it love? Is it superficial? These are questions that Nagi would get to answer as his character develops. I wouldn't really call it superficial though. It's love of a virgin heart, let's cut the guy some slack ^^.
3. Couldn't have Maya played the role she needed to without that added complication?
-- She could have, but as we have seen, she has no control over it. These "complications" arise as the story progresses. It gives rise to controversies that pique the interests of young minds such as ours. Well, I sincerely have no issues against these controversies though, since I am indifferent as to who Nagi would choose in the end. And that's why we live to see who that person is ^^.
4. Or does Nagi's feelings (and Maya's I suppose) have greater plot value then the author's letting on?
--Could be, or could be not. Who knows. Maybe Oh Great! is just following the rules of manga by adding these messed up web of love between the characters. Maybe it was meant to add interest to the story and plot. Maybe it's just a way of expressing comedic relief. In the end, it's HOW the readers interpret the plot, and not much of how the mangaka conveyed it.
Could've sworn I posted something regarding this... Ah well. Sorry if I'm reposting my views.
I really think that Maya has interest in Souichirou because of his powers. That's why I think she said that she would have married him if Aya hadn't claimed him--she saw her potential as a warrior, I don't think necessarily because she's in love with him.
I'm officially pro Maya-Mitsuomi, so maybe she was gonna pull a Mitsuomi-Shin's girlfriend number? I don't know. Maya's kinda complicated because she seems very confident and she's pretty strong but she feels as though she's only a sheath for the Reiki.
