Rainbow Sonic Boom at Tresen Academy

I transmigrated into the world of Uma Musume and became a rainbow-haired horse girl. Never mind the inexplicable sense of deja vu or the absurdity of being able to run fast enough to create a sonic boom. Why do I have memories of the dark horse-racing world? And what's with the scar on my face?! Could this be the world of warhorse girls instead of Uma Musume?!

"Miss Dauntless Pegasus, what do you think about your opponent's online claim that you're a bad sport for flying in a race against runners?"

"Fake news! I don't even have wings. How could I possibly fly? I suggest that this little horse girl go back and study physics instead of going around misleading people!"

"Uh... So, what do you think about the race?"

"Well... running comes first, friendship second, and Nature third!"

"You son of a horse!"
