The anime horse girl who's terrorizing gacha players in Umamusume is based on a real, chaotic racing horse who once instantly obliterated 12 billion yen in betting losses

If you've been on social media at all this week, there's a good chance you've encountered the horse-crazed masses who've succumbed to the absurd siren call of Umamusume: Pretty Derby. It's a gacha game about horse racing, except the horses are anime girls, and it's got a pretty compelling spreadsheet simulator underneath all the gratuitous wobbling and the inherent villainy of its gacha trappings.

Of the titular umamusume, one horse girl has quickly become a fan favorite since the game got its western release at the end of June.
