Uma Musume: Cinderella Gray Gaiden - "Bangai"

Obey Your Master

オベイユアマスター

Obey Your Master is an American Umamusume who travels to Japan to participate in the international Japan Cup. While depicted as having an over-the-top demeanor that Japanese citizens view as typical for Americans, this is actually a facade she crafted by emulating a friend to make her opponents underestimate her.

Dicta Striker

ディクタストライカ

Dicta Striker is a student at Tracen Academy, first introduced when Oguri Cap transfers there. After Oguri's first string of victories in races, Striker begins seeing her as her rival. Unfortunately, she would repeatedly miss chances to race against her; first, Oguri did not qualify for the Triple Crown races, and she then turned down a direct challenge from Striker, as she was already intending to run other races.
