   6 agents from Japan were sent to Seoul to find the hidden base of the Ravens, though they had to blend in the crowd to avoid unnecessary attention while on this Mission.

   While "Blending" in they decided to go back to University to find any clues about the Ravens, but instead they cross paths with 6 boys that will change their lives forever.
