When  some  rouge  spirits  start  harrassing  a  local  forest, and  get  their
clutches on Azusa; Yohko manages to save the day.  Then the really bad
news  starts,  when  their  fight  awakens  the  demon  king.  Not  much  is
really said about him, although he seems to be tough enough that perhaps
even Yohko can't handle him alone.  He is the only minor character
introduced in episode 2.
