Uma Musume: Cinderella Gray

Uma Musume: Cinderella Grey — Finally, something that's off the usual trodden path of the field...that's even better than the mainline series itself? Horse Girls, make them female and give them a demihuman representation, and you have quite the double trouble awaiting you on the racetrack. Since Spring 2018, with the arrival of P.A. Works's adaptation of Uma Musume: Pretty Derby, one of a handful of IPs from one of the best modern game companies, CyGames, the series may have started in Japan all those years ago. But with every new iteration of the anime series, which has now brought about a large franchise, fans of UmaMusume are going bonkers left and right, with the latest development being the official English version of the game that has been recently released for smartphones on June 26 of this year (2025) (it's fairly new as of this review) so that international fans are not left out of the Uma Musume craze. Most importantly, in the context of the anime mentioned above, is a manga series that's part of the Uma Musume franchise but one that has its deep roots within the Japanese racehorse history books. This is the spin-off series of Uma Musume: Cinderella Gray, which features Oguri Cap and her claim to fame in Japan that's situated between the time of the late Showa era and the early years of the Heisei era, from 1987 through 1990, produced by Junnosuke Ito, illustrated by Taiyo Kuzumi, and written by Masafumi Sugiura, scriptwriter for Season 1 of the mainline series that has been serializing since June 2020. While I'm not going to do an overview about the real horse reference in question (you can read that for yourself on Wikipedia), the criticality of Cinderella Gray is where the series lies in the many veins of the Uma Musume universe. To be specific (as a pseudo-spoiler alert), you will recognize some of the horse girls who appear in this anime as the generation before the mainline series, but if it's in the vein of Oguri Cap, it's pretty much a prequel to the mainline series, being somewhat way back before Uma Musume's Tracen Academy was even a blip in the eyes of others. The story starts off at Kasamatsu Academy with its own home of horse girls, though if they were to compete competitively, it would only be on a regional level as compared to Tracen Academy aiming for the national and international levels. If you need a direct comparison to how Oguri Cap is like in this spin-off series, think of her similarly towards Season 2 of the mainline series where Tokai Teio takes centerstage, and the talented horsegirl that has a goal to make herself big, at least on a national stage. In Cinderella Gray's case, Oguri Cap has only one important mission to do: run as fast as possible and outdo her competitors, even if the country bumpkin herself doesn't see favour with the rest of the Kasamatsu Academy's horse girls. Namely, their version of the BNW girls of Biwa Hayahide, Narita Taishin, and Winning Ticket, through the likes of Norn Ace, Mini the Lady, and Rudy Lemono, alongside her good horsegirl buddy friend Belno Light and the trainer that makes all of her dreams possible: Joe Kitahara. As with every Uma Musume iteration, trying to push your limits towards the likes of national horse girls is a very tall order, but much like Tokai Teio's spirit, Oguri Cap does things the same, keeping her mother's dreams in mind as she makes it out to the local Kasamatsu Academy to refine her steps, one race at a time. And though she comes off as aloof (which gives some comedy space to her character), even under the pressure of the group of bullies who would try and sully her, she only has her ardent supporter of Belno Light help bail her out of trouble and take care of her everyday needs, like a helpless mother figure to her otherwise monotonous horse girl daughter. But still, the heart of Uma Musume is readily there, as Oguri Cap soon proves herself under the training of Joe and amasses local wins enough to make it to the famed Graded races in Japan, eventually meeting with her generation's bigwig rivals of Tamamo Cross, Super Creek, and Inari One (though they too appeared briefly in Season 1 of the mainline series). It's classic Uma Musume through and through. No doubt that with a CyGames IP, both P.A. Works and Studio Kai have experimented much with the mainline series, and they did an admirable job, considering that their animation arm was established but not ready for full-time anime production at the time. And come 5 years later, with PriConne's adaptation being the very first primetime anime production back in Spring 2020, after the mainline series' Road to the Top movie, CyGamesPictures is back with a vengeance, tackling their own IP franchise, and Cinderella Gray defintely benefits from an in-house, home-ground playing field of an immense production and great animation. No doubt that the studio has done well with the underrated hit of Apocalypse Hotel this Spring season as well, so it shouldn't really come as a surprise when the interconnected IP gets pretty much the same treatment as well. Really some great work that continues to seed the great image of CyGames and their animation division. The OST, I think, is top-notch, but given the work records of music composer Kenji Kawai, that's pretty much a given. And while I find that [Alexandros]'s OP here was decent, knowing their track record on Ao Ashi's 1st OP makes me feel that there's something holding the rock band back that feels incomplete. But not a bad effort at all. Even Oguri Cap's VA's ED performance is alright; there's not much to say about that as an above-average song. As the first spin-off in a rather huge franchise, Cinderella Gray just adds another layer to the Uma Musume complexity that's to be expected from the stories of real-life Japanese horses, but given CyGames and its flair that just makes the marriage of history and modernization all that powerful. And yet, this is only the 1st half of the split-cour adaptation, so expect more things to come when the anime comes back in Fall. Uma Musume: Never doubt the competition, because you ARE the competition.
