I agree with the other reviews that this season was better and more eventful, however I feel like a 3rd season is necessary to explain some backstories. I feel like there were a couple loose ends that they failed to explain. For example:
-the guy from the Hyou family just suddenly decided to leave Shuurei alone doesn’t make sense
-shusui’s relation to the Hyou family
-the Hyou family in general?? (The ghost + Riou)
-the corrupt Ou Ki story
-what is Seiga’s deal tho???
I can go on forever but despite all this, I THOROUGHLY enjoyed the anime! I rly liked the second season, especially certain new characters (Tan-Tan!)
