Man, a lot of talking about Yuri-chan and Akane-mama, but surprisingly nothing about the whole class suddenly bowing in such a well-coordinated manner that it makes the Chinese army look like a bunch of clumsy amateurs.
As one Niconico poster said:
"Yes, yes, now this is a group of well-trained perverts!" LOL.
Jokes aside, it's such great closure on this part. With some juicy details too, we didn't see how much the family let Sou explain what happened without throwing one of their fits and shutting him up, but apparently the family did know that it started with something between Hana and Sou. A shame that there will probably not be enough space to let the family meet the Konnos and Kakki.
I see some complaints about Yuri's success, and I honestly don't see where they come from.
The series constantly shows that good self-control is a rare and highly valued characteristic in the 1:39 world.
Sou started interacting with her because she was funny to tease, and then he thought of her as someone detached enough from him to be objective but good-willed enough to be reliable.
The family started to get the idea that she's exceptional when they tried to corner her and she landed a counter right to the jaw by making them know that not only was she not part of the problematic bunch that hugged, but that she was the one being hugged (Sakura called her onee-chan in that scene as well, IIRC).
Her mental pandemonium was exceptionally good at handling the high pressure that made everyone almost pass out without showing distress.
What more are you asking for?
The humor is about her getting highly sought-after stuff she doesn't ask for, not about her being unfit for it. She isn't King from OPM.
