I found
this small piece of information on Famitsu today:
The ending theme for the Sky Girls TV series is named
True Blue and it's going to be performed by
Gotou Saori who is also Sonomiya Karen-chan's seiyuu. <3 She also performed the OVA's ending theme, which was called
Shooting star.
Virgin's high! (by
MELL) was already mentioned as the opening theme for the TV series.
BTW, Elize (the blonde character) looks so darn cute from those design drafts. <3 Hoping for another
tsuntsun "forehead-chan" like Minase Iori from the Aimasu anime. Elize's seiyuu, Tsuji Ayumi, played mostly minor roles in the anime world. Her recently completed one was Venus Versus Virus' Laura/Lola.
