I mean, I guess this was a decent episode if it means more character background and information. Still not as deep as it could be as it was mostly surface level. It was pretty calm and didn't have much going for it. Pretty much 0 threat at the moment which is not bad if you treat it as a CGDCT show. There seems to be a lot of hints with Renge lately that we do not know much about it, but each episode contains a little revelation so far.
