In case that brief plot synopsis wasn't enough of a clue - Yes, it appears that episode five of this series has entered us into the world of the filler episode. With Haru supposedly away having a medical following his exploits in the last episode, it's left to Minamo and Sota to steal the show, with a light-hearted and ultimately entirely pointless little escapade.

In all honesty, it wasn't too bad as filler episodes go, but then again it wasn't actually all that great either. We didn't learn anything new, the fighting sequences were cool in that rather jaded 'oh wow, martial arts!' way that seems to plague every fight scene in every form of cultural medium these days, and.... well, let's just say if you miss out on this episode I don't think you'll be regretting it late in the series.
Roll on episode six, and hopefully a return to the proper point of the show. I was really expecting Real Drive to be largely filler-free, or at least with enough quality in hand to provide something more interesting than some cheap light relief, and perhaps it's that believe that's left me so disappointed in what I've just seen here. Like I said, it's not a bad episode in the grand scheme of all things anime, but I really can't dish out any points for effort after such a weak attempt at a side-story.
