In the Toriko series would you like Guilty to return to having a "normal" female cast or would you like them to continue the theme that started in Homura of having a slightly stronger cast of female's (at least in the physical sense).
Personally I think a mix of those two options would be a good thing - basically out of the 5 female cast we usually get, have 2 - 3 of them know martial arts, or be physically stronger then the rest of the female cast.
Naturally one of those reasons is that one of the female's would be already an adult, who is usually stronger compared to a teenager...
