Welcome to Tracen

The portal opens on Tracen Academy's summer festival, and everyone is enrolled for the day. Join IRIS Interactive for a free immersive Umamusume: Pretty Derby event: live Umas in character, races and idol performances on the main stage, crafts, games, festival food, and a mystery to solve before the last race is called. Come as an Uma, come as a Trainer, or come to watch. The gates are open from noon to seven.

Meet the Umas

Activities

Free

Main Stage

Races and idol performances all day: Make Debut, Yume wo Kakeru!, and the Tracen Ondo, plus a guest taiko set by Ryukyukoku Matsuri Daiko and an aikido demonstration. The SPICA Trainer keeps the program moving.
Free

Off to the Races

RC car racing against the Umas, presented with Kawaii Crawlers RC. Line up at the gate, wait for the fanfare, and try to beat Maruzensky to the finish.
Free

Classroom Chaos

A teru teru bozu craft session in the Tracen classroom. Grass Wonder, Seiun Sky, and Manhattan Cafe will help you charm away the rain clouds.
Free

Running Wild

Tokai Teio, Mayano Top Gun, and Kitasan Black are loose on the festival grounds. Say hi, take photos, and see what they drag you into.
Free

Are You Smarter Than An Uma?

A live game show. Face off against Agnes Digital, Gold Ship, and Obey Your Master in rounds of trivia and challenges. They don't have to be right, and neither do you.
