This was made into the first half of the third OVA. And yeah, it was so much chaos, and very befitting of an OVA. At the time I watched it, though, I hadn't actually started watching Season 2, so when Paula and Haru came in, I didn't really recognize them outside of their appearance in the intro animation. I clearly understood Haru was Kosaki's younger sister and mistrusted Raku, and that Paula was an associate of Seishirou, but beyond that I didn't really know what to expect from them.
The shamelessness of Marika in scaling the divider wall. Does she not even think about the fact that other men are almost certainly on the other side? This is why I keep saying she's deranged. No decency whatsoever in that girl. Even if it was just the two of them, you don't just do shit like that.
Also, the bath house lady saying only 'old farts' come in when four young girls and a young woman (Honda) just walked into the women's side not that long ago. How irresponsible. And what a perfect setup for cliche shenanigans. He really shouldn't have tried to take care of that first request, to be honest, but, well, we wouldn't get the funny, otherwise, I guess.
