Damien Kellis hits bulls-eye with this question:
Why are most of the customers in the Maid-ish Cafe female? Fushigi mystery.
On second thought, Kampfer is so full of manifest impossibilities, that this one should count as something very minor.
Thanks to the opening and ending animations, the identity of this New Kampfer is no surprise. What I did find refreshing was that the Obvious Questions asked in the usual fan-speculation manner are, if not answered, then at least acknowledged: where do Kampfers come from? Why are the Messengers all from the same toyline that apparently only Kaede [Sakura] likes? Is Kaede involved in this somehow?
Obviously I need to find a less obvious topic about which to speculate.
