Director Commentary for Episode 5 (Mitsugo Biyori ~2-ransei~):

I'm quite fond of the clerk in the underwear department (Which is why she appears in episode 8 as well)

The cut where Futaba slowly rises from the underwear was inspired from the launch scene of my favorite show, Space Battleship Yamato (https://youtu.be/G_p1-Qm-3SA?feature=shared&t=270). To accommodate, a jet engine sound was requested to be added.

In the pool episode, Hitoha utters "Damn pig!" for the first time but, for some stations,
this phrase was censored. What a shame.

The Parent Day section is very much a favorite of mine. In the manga, Soujiro screams and runs out the classroom, but,
there was an opportunity take it further. Because of this, I wanted to make best use of the CG-made hallways with him storming through
the halls, breaking through glass and diving onto the police where he's finally taken away.

The running scene was also a homage to Episode 74 of Urusei Yatsura "Ghost Story! Old Man Willow!!" and right before Soujirou bursts through window, he strikes the classic Rumiko pose. Since animating on CG was such a problem for the animators,
I took the responsibility of drafting the key frames

Combined with Misawa-san's work on the police theme, this created a ridiculous scene.
