From eManga:
It is a time of great unrest. A lone ninja wandering in search of his life’s path unexpectedly finds his destiny when he crosses paths with a shrine maiden escaping a terrible fire that was intended to kill everyone at her temple. Together they find they are part of a much larger purpose, as fate brings them into the fold of warlord Sanada Yukimura who is gathering ten of the bravest he can find. Ten who will not only bring him victory, but become the stuff of legends. Kairi Shimotsuki brings an exciting tale of action and intrigue based upon the Edo era legend of the Sanada Ten Braves.
