Trapped at Tracen: A Trainer's Endless Three Years

At Tracen Academy, a group of Uma Musume live their lives. They have adorable animal ears and tails, and simple personalities. In his previous life, he had loved being locked up in the Uma Musume mobile game. After arriving in this world, he should have become a trainer and spent three years striving alongside the Uma Musume toward the future. But the Three Goddesses had other plans. "Lamb-kun, Uma Musume are idols to humans, but can't humans become idols to Uma Musume too?" "You! Go play Uma Musume: Pretty Derby!" "Since you loved being locked up before, there's no harm in doing it again in this life, right?" The Three Goddesses came to him in person and demanded that the poor transmigrator become an idol for the Uma Musume. But why did he have to livestream himself playing Uma Musume? Why was he still being locked up after coming to the world of Uma Musume?! Anyway, another three-year run between being a trainer and being locked up began! He livestreamed under a hidden identity while working at Tracen, but gradually, a whole crowd of Uma Musume gathered around him. Just like the Uma Musume in the game, they always gazed at the trainer with possessive eyes. Could the game and reality be connected? Some trainers' souls are forever locked away in the basement.
