Episode 18

Unbeaten Champion (無敗と連覇, Muhai to Renpa) is the 5th episode of the 2nd season Uma Musume: Pretty Derby anime.

Summary
The day of the Spring Tennoushou is just around the corner and fans of either racer argue whom will be the winner of the race. On Gold's personal online video channel, she interviews Trainer that instantly falls apart.

Tokai trains with Daiwa and Vodka, while McQueen trains with Gold and Spe, and the two of them easily out run their teammates. Trainer notes how both McQueen and Tokai have powered up significantly. At another time, Bourbon is once again chased by a stalker and manages to once again out run the person. In the Fortune Teller tent, Mejiro Palmer accompanied by Daitaku asks about how the Spring Tennoushou race will turn out as she's participating in it. Matikanefukukitaru foretells that Palmer must ultim-outrun her competition.

While jogging, Tokai runs into Turbo and the two briefly talk. Eventually, the day of the Spring Tennoushou race arrives, Tokai and McQueen do some early morning practice. By the time of the race, the two commentators, Misato and Junko give their thoughts and opinions on both Tokai and McQueen. They sequentially introduce the other racers partaking in the race and in the audience watching is Nice and Ikuno. Walking down the tunnel way onto the racetrack, McQueen and Tokai have a brief chat with each other. McQueen exits the tunnel first and receives a warm introduction that's sadly only 2nd to the introduction that Tokai received.

Right before the start of the race, Palmer finds a broken piece of McQueen's horseshoe on the ground and because of this the race is temporarily delayed until it's mended. Once the race finally starts, McQueen manages to out pace Tokai in it and win. Although, Tokai is disheartened by the loss, she doesn't hold it against McQueen and embraces her while congratulating her for her win in the race.
