This is a promice of even more hilarious development in every sense of the word.
By the way, I sometimes want to see Chio developing same way as Hitomi from Hinamatsuri. Except Chio always stays JK no matter what insane stuff she "plays".

I can't recall any chapter that was totally brainless ecchi. The closest I can think of is the going commando one, and even then I still liked the group dynamic. Or maybe the chapter before this one? But it was mostly talking and even when they stripped we never got shown any egregious groping (though I imagine it probably happened).
I think most of the ecchi stuff in this manga either works with or at least accompanies some genuinely fun jokes and scenarios. Are you of the opinion that ecchi in any context is automatically brainless?
@IHavoc
the only time i really felt like it was too far in the ecchi zone for me was whenever it spent time focusing on the kabaddi stuff. the ass-poking part was obnoxious too, even though that's a real thing kids do in japan. i don't think ecchi is inherently bad, but it suits a harem manga more than a comedy manga imo.
