Used a machine translator for the Japanese version.

(The Alarm Clock in Umamusume is a consumable that lets you redo a race. Diegetically it turns the race into a "bad dream" that you wake up from. Though the fandom often memes it as some sort of time-rewind ability by the trainer.

Anyway, in the game you can only use the Alarm Clock "race reset" feature for a maximum of 5 times in an uma's career run. And Mirako has already hit this limit.)
