(Spoilers in this review)
The first half of the episode involves Hime doing some part-time work as a model. Nozomi is essentially blackmailed into doing some cosplay with Akechi, a character who was introduced in this episode, who is dating Inukai (who is also a girl), and who is quick to remind Nozomi that working part-time is against school rules. After some talk about career choices, this half ends after Nozomi confronts Akechi over the fact that Akechi also works part-time at a maid cafe.
The second half of the episode involves the main trio reminiscing about the joint class they shared with merfolk. Kyouko turned out to be popular with the guys (it seems like merfolk were attracted to squinty eyes, which were how mermaids were drawn in original Japanese legend), Nozomi was harrassed by a mermaid who was a BL fan and who thought Nozomi looked like a boy, and Hime was stared at by lustful mermen.
Viewers were also introduced to Shizuura, a mermaid who is carried around by her childhood friend, Koma, since she only has fins. Koma looks into acquring some sort of device that would let her walk, but Shizuura talks her out of it.
Centaur no Nayami continues to try strange attempts at social commentary. The constant pushes for equality above all else (including civil rights and life itself, according to the teacher in episode 1), seems poorly thought-out, insensitive, and just awkward.
Akechi’s behavior during this episode was also troubling. From blackmailing Nozomi to groping Manami (in front of her girlfriend, no less), this girl is out of control wild child. How she gets away with such behavior is beyond anyone’s guess. The way the mermaid treated Nozomi also was not okay. But it seems like the series is swiping at anything to get a laugh.
Perhaps I’m getting too analytical and critical for a series like this. I do appreciate that there’s an actual lesbian couple. But Centuar no Nayami has not been a very fun watch so far.
