Shiro Kawamoto is a hunter making ends meet in a country changed during Commodore Perry's fateful visit. His encounter with an American named Geoffrey Brommel brings him on a path of vengeance. At first, the two were nothing more than acquaintances, but when the Americans incur the wrath of a mythical kitsune, his life, and his country, hang in the balance. The mythical fox leaves him with one warning: deal with the Americans, or all of Japan will suffer. With little options left, Shiro must take matters into his own hands, yet his own timidness and lack of English speech put him in more danger than ever. If Japan is to ever know peace, then Shiro must decide between taking the peaceful approach, or defending his homeland, no matter the cost.
