Amazon have uploaded the manga cover art. Thanks to their zooming applet it is just about possible to make out the character profiles on the cover:
Ascoeur
GTO associate ES Member
Rank: C-
Birth: SC0363 10 Aug
Age: 16
Sign: Leo
Blood Type: O
SP-ability: Push-pull
Item: Comb
Shorts colour: White
Q-feuille
GTO associate ES Member
Rank: C-
Birth: SC0363 21 Sep
Age: 16
Sign: Gemini
Blood type: A
SP-ability: Parfum
Item: Choco Bon Bomb
Shorts colour: Black
..for "shorts", read "panties".
I now have the manga and have made a couple of corrections to the above where I misread the blurry text on the Amazon image (I misread 10 Aug as 16 Aug, "Choco Bon Bomb" as "Choco Bon Bon" and their rank is "c-" (c minus), not "c")
The Japanese version of their profiles at the back of the manga also has more detail. Ascoeur's comb is described as both a "needlegun" and a "beam sword". Q-feuille's has no furigana so isn't as simple.
