Watching the fake Demon Lord act as her trainer, the Savior wondered: Was this really okay?
Watching the Savior act as his Uma Musume, the fake Demon Lord seriously wondered whether this girl had even the slightest trace of a savior in her. A dragon girl competing against Uma Musume was ridiculous enough already.
This is a chaotic, disorderly story. You might see a dragon girl training alongside a group of scrapped Uma Musume whose stats are practically on par with hers. You might even see Uma Musume from different worlds competing against one another. After all, the scrapped world connected to the main one links to more than just a single Uma Musume world, so anything is possible.
(Could we see stories about Tokai Rudolf and Symboli Rudolf, or Gold Ship racing on Mars in a Gundam?)
(Quiet. You're asking too many questions in this slow-burn story.)
