I just wanted to rest in peace. Why did I have to reincarnate into this world???

Ren regains the memories of his past life, expecting to live a normal second chance in an ordinary world. However, as fragments of his current life resurface, he realizes the truth-this is no ordinary place. This is the world of Uma Musume, where girls with horse ears and tails captivate the public through the wildly popular sport of horse racing. As a former player of the game, Ren can't help but feel thrilled. What fan wouldn't dream of becoming a trainer and guiding their favorite horse girl to victory? Determined, he sets his sights on that path. Unfortunately, Ren regained his memories far too early. None of the beloved characters he once knew have debuted yet, leaving him in unfamiliar territory.
