Spica figuring things out faster than the protagonist is hilarious. She's got such an emotionless expression, just accepts the ideas Ares puts forth, and gets stuff done efficiently. She's secretly the real protagonist. Toudou's magic boobs are also hilarious, like a hidden air bag for little girls who fall into her chest.
@BCS: Ares thinks Toudou is a boy, hence why he uses male pronouns.

I think that would be missing the point, since none of the characters are trying to keep the gender ambiguous. All of them think they know which gender Toudou is, but some of them are wrong.
