Weird tropes find their way into anime, and I’m not just talking about tentacle porn. Judgment aside, cat girls, superpowered transfer students and Vespa-riding aliens are objectively a little eyebrow-raising as television plot hooks. To be an anime fan, you get used to things you wouldn’t normally poke with a five-foot pole. Regardless, I was completely unprepared for Uma Musume Pretty Derby, a “moe anthropomorphism” anime that, like others of its genre, portrays non-human subjects as megacute people.
