Uma Musume: They're Peeking at My Diary, All of Tracen Was Excited

Xu Zong accidentally traveled to Tresen Academy and became Spica's trainer, activating the diary system. He earned rewards by keeping a daily diary about his horse training. However, Xu Zong had no idea his diary would be read by horse girls like Tokui Zhou, Narita Road, Zhuo Fu, Donghai Emperor, and Northern Xuanju. Mebiro McQueen: "Wait, the fat horse in the diary, it's not talking about me, right? How am I fat?" Emperor of the East Sea: "Why does everyone know that I like to drink honey?" Narita Road: "Who's the crybaby? I... Even if I win, I won't cry, probably!" Excellent Quality: "Why do you say I'm a bronze medal collector? Woo woo woo, trainer, you're so mean." Northern Black Horse: "What's an assist card? Beware of the Hammer? Who is the Hammer!" Satomi Mitsuru: "Huh? Why do you call me Brother Diamond?" Teju Zhou: "Who is Teju Dai? Wait, do I have a sister?" Airi Hayabusa: "Is Shima an isotope in a parallel world?" Xu Zong's diary is full of strange things, and the horse racing girls are all looking forward to it. As the content becomes more and more, the horse racing girls learn more about isotopes in parallel worlds.
