Uma Musume Pretty Derby: To The Basement Novel

A guide for trainers at Uma Musume academy outlines strict behavioral protocols. Trainers must avoid all romantic involvement—with colleagues and Uma Musume alike—and maintain professional distance at all times. Physical contact is prohibited, including head pats, touching ears, or touching tails. Trainers should decline meal invitations from Uma Musume and keep their rooms secured at night. Should disturbances occur, trainers must remain inside and contact security rather than investigate. If an Uma Musume confesses romantic feelings, trainers must politely refuse without revealing emotion, then immediately seek campus protection and potential resignation assistance. Male trainers who are particularly handsome, charismatic, and gentle in demeanor are strongly advised to resign, as remaining at the academy will lead to inevitable consequences in the dark basement. Mizuno Sora, a trainer with perfect evaluation scores in Appearance, Scent, and Voice, faces an internal conflict regarding his future at the academy.
