Ok this'll probably be my last wild speculation and one I don't think anyone has mentioned either, but Solution 9 is Macross City. Five gil says those hover bikes can change into dirt bikes; since we know there are dirt bikes shown in some of the newer Solution 9 artwork. The enigmatic maiden is some sort of cross between Lynn Minmay and Misa Hayase (Lisa Hayes for those who only know Robotech). You can't tell me she doesn't look like she could start singing a very catchy pop song all about love and hope while just actually being a very good diplomat.
