Just my opinion, but the only way Diana could have been a worse character was if she had renamed herself 'Lynn Minmei'. Anybody who remembers the original Macross series knows what I'm talking about.
@Talh The actually issue is that Diana isn't the intended user for the spell. It's actually the ultimate yandere attack spell. So that the TARGET of their affection knows how VERY much the yandere loves them.

Heh, I remember when Speed Racer had new episodes coming out (near the end of the series, I admit), and watched the original Macross saga on T.V. (known as Robotech here in the U.S.). Heck I used to watch Gatchaman (A.K.A. G-Force) every afternoon. O.k. this is making me feel old now so maybe I'll watch Bubblegum Crisis or something.
