Real-life figure Miyamoto Musashi was the most celebrated samurai of all time.

The quintessential warrior philosopher, Musashi authored A Book of Five Rings, a theoretical guide to military strategy still used today.

Musashi sets out for Nara intent on challenging the warrior monks of legendary Hôzôin Temple.

But will Musashi's growing feelings for his childhood friend Otsû prove to be a fatal distraction in his match against In'ei, the austere master of Hôzôin's deadly spear technique?
