Shion and Rat have risked everything to reach the top floor of the Correctional Facility, but their rescue attempt of Safu may have come too late as it appears the Safu they once knew is gone forever. As Rat rushes to find a way out, Shion must make a heartbreaking decision: leave, saving Rat and himself from capture, or stay with Safu and find another solution.
