A helicopter carrying top-secret plans crashes, igniting out-and-out chaos. Musashi is on her own as she faces off against armed terrorists who'll stop at nothing to retrieve the documents. But events take an unexpected turn when the plans are intercepted by a student who can't be trusted to comply with Ultimate Blue.
As Musashi works to recover the dossier, gang warfare erupts, distracting her further from her goal. It's another race against time and struggle against the odds for this teen-age secret agent.
