Guardian, Saviors of Kamigawa

With the kami poised to overtake the mortals of Kamigawa, a black magician must set aside his own pursuits for the sake of the greater good
 
The victory of the spirit world is at hand. The ronin Toshiro "Toshi" Umezawa has sought to avoid the great conflict between the spirit and human realms. But despite his best efforts, he’s not only involved in it, he’s at the center of it. Together with Princess Michiko—daughter of Daimyo Konda—he must find a way to stave off the impending victory of the kami, while preserving his own life in the bargain.
