It is up to Yusuke, along with the assembled Science Police, to use the various powers of Kuuga in order to stop and defeat the Gurongi Tribesmen from their continuous killing and ensure the happiness of others. However, as endgame draws near, Yusuke learns that there is a horrible revelation behind Kuuga and the Gurongis' leader.
