As diligent as he was at practicing with his blade, it didn't change the fact that Sanshiro Yuzuki (Osamu Sakai) had neither the skill nor the confidence to excel. When his samurai father was slain by a cloaked gang of thieves, the grieving son was approached by an otherworldly spirit (Tokio Oki) offering him an edge for vengeance-a potion that would render him invisible. Laugh-leavened, underseen (sorry) action-fantasy co-stars Yoko Atsuta, Sanshi Katsura. 78 min. Widescreen; Soundtrack: Japanese; Subtitles: English; audio commentary; featurettes; image gallery. In Japanese with English subtitles.
