Welcome to Raven University! Kung saan hindi pang akademikong asignatura ang iyong aaralin, kundi kung paano lumaban para mabuhay at... pumatay. This secret and hidden school is built where abducted persons train for combats and play a human dark game. Where fighting is the only thing to stay alive...and killing is the only way to escape. Beware! Your comrades can turn as your killer today. What will you choose to shed? Blood or Tears?
