So, while I am a little lost as to Langris' motivations, I can also appreciate what he does this episode. The spectacle we got to witness was really something interesting, and it effectively opens up a handful of paths for where his character could go now. As for the rest of the plot, we're going to be tapping into that starting from next episode, and it seems mildly intriguing, so I hope it's not just boring. It is, however, very comical that a vast majority of people attending the training arc are just the Black Bulls.
