This was the very first announcement trailer for Uma Musume, released back in 2016. It caused a bit of a stir because stable owners looked at it and thought Cygames was turning their horses into lesbian smut for kimoota, so they protested, threatening to revoke the licenses. The game then went into development hell, to the point where the promotional anime was released two years before the actual game.
