Opening a Secondary Account in Uma Musume's World

I've been transported to the world of Uma Musume, but now I'm forced to constantly earn emotion points with a system I'm not sure if it was created by the Yi family! So... is this system really not from the Yi family? What's with all this card pool stuff? Thankfully, the characters are pretty good, but the boss battles are a hassle... Anyway, let's start from all corners, take on the central protagonists with multiple bread and cheese, and run! Also—why haven't all the Uma Musume authors updated yet? I, a reader, have already made a fortune, you idiot!
