Yukio's Temporal Weeks in Umamusume: Pretty Derby!

Asahi Yukio is a 17-year-old boy with no friends, and honestly, he likes it that way. Lazy, reclusive, and completely absorbed in gaming, he leads a quiet, uneventful life. That is, until he decides to work for a company called "Hololive" for a while. One random day, Yukio finds himself at some bizarre Human-Animal hybrid reunion. Among the chaos, he meets a group of horse girls known as the "Uma Musumes." Things quickly spiral out of control, and in the middle of the madness, the Trainer makes a strange request: could Yukio switch roles with them, for a decidedly unknown reason. Exhausted by the commotion, Yukio agrees without a second thought. Little did he know, this impulsive decision might just turn out to be a surprisingly good choice.
