Ironically, reddit has apparently blocked the r/anime bot. (Presumably related to all their api changes.)

this time you’re a mermaid fighting Abyssal Evil. Sounds cool, right? Has it been done before? Not even close, and we’re here …

Kind of, in Aquaria, though its more of a metroidvania.

As romcom misunderstandings go, at least the one in this episode didn’t feel too contrived.

I still hate it, though! :)
