My Uma Musume Secret Identities

As a devoted fan, our protagonist transmigrates to the world of his dreams: Uma Musume.

He originally wanted to create a dark horse-racing world, but all his secret identities defected to the enemy, Trape Academy.

Huh? Why do my secret identities seem more like the protagonists than I do?

Wait, I'm basically an utterly evil villain now!!!!!

Some Arisu: I'm the protagonist, damn it!
