 The remaining participants proceed to the next set of puzzle rooms . As Sigma , Phi , and Tenmyouji complete their room , they uncover a holographic message of the old woman , the same woman Tenmyouji has been looking for , Akane Kurashiki . Akane and Zero Sr. had developed the AB project , a project that encompassed the Nonary Game and the Ambidex Game , to train Sigma and Phi to transport their consciousnesses through time . This occurs shortly thereafter , and this time , they subdue Dio before he can kill Akane . Akane explains that the game 's dangerous elements were necessary to speed up one 's brain to transport one 's consciousness through time , and each participant was infected with Radical @-@ 6 to amplify this increase . The Nonary Game was designed so Sigma and Phi could experience multiple timelines and retain what they learn in each one . Sigma and Phi 's consciousnesses are then returned to the present , where they find everyone has cooperated to acquire enough points to escape .
