From the back of the book:
The Shinkoukenjin are the mortal descendants of the four guardian gods of Kyoto. Together, they fight things that are beneath the Shinigami's notice. Things that have nothing to do with the spirit world. They fight horrors that are alive and well, that threaten mortal life and limb. Sometimes they win, sometimes they lose, but they always fight with honor and integrity.
