The manga starts off with a very odd killing. Then, it jumps to a few days later where Yousuke (not to be confused with Kyousuke) ends up breaking a small shrine. It later gives him the guardian Suzaku--just in time too, for he must face the murderer that opened the manga. As it progresses up to the four volumes as of this summary, it introduces the other three people who also have guardians, that destroy monsters.
