You haven't already embraced the crazy? Keijo!!!!!!! was my favorite anime of last season, and it was "stupid". If you have fun with something, who cares if it's stupid?
First off, Darkness is best (although my appreciation of Kazuma has rapidly skyrocketed as I've realized how central he is to my enjoyment of the show...). Secondly, yes, I am also very much happy that they're giving her more screen time. Episode four was perfection.
