"How long will the word "incest" will keep Kotono at bay?"

Go ahead and add that one to the pantheon of great anime philosophical quandaries...

About half of this episode was the brother literally listing off the unique charms of his sisters that he is totally not going to change around now that he has the combined backing of both the fandom and the law. Glasses girl's entire scene has reduced her character to 'the one that says lewd things with a straight face'. Author-kun is struggling already to craft a narrative and keep the fanservice up to par without stepping on each other.

That said, Minami has already stolen the best girl title, as I'm sure you all agree.

I feel sorry for Shion, as he gets little screen time as he doesn't have his sister's affection, and is practically absent in the OP, I noticed. I wonder what his character is going to be used for, narratively?
