On this episode, Kazehaya gets a reward from Ellis. Later, he helps Ellis with another problem.
So it's cool to learn more about Ellis and her background. Also it seems there will be another antagonist on the next episode. Although I wonder if Ellis will ever find out that Kazehaya is Ren Ashbell and will Claire ever stop being emotionally stupid? Other than that, I can't wait to see Kazehaya do another face off. Overall, a filler for the next plot and some fan service.
Conclusion: A filler for the next plot and some fan service.
