Hiiragi--39-s Practice Diary -final- -k-drive-- 〈2026〉

The practice diary wasn’t a notebook anymore. It was the K-DRIVE itself—every run, every near crash, every impossible turn recorded in its black-box memory. She’d named the file system Hiiragi’s Practice Diary on a whim as a teenager. Volume one: learning to balance. Volume thirty: mastering the corkscrew drift. Volume ninety-two: breaking the district speed record.
