Game Over (Mastermind!Chiaki Au)

WARNING: HEAVY SDR2 SPOILERS AHEAD. IF YOU HAVE NOT FINISHED SDR2 PLEASE DO NOT PROCEED UNLESS YOU WISH TO GET SPOILED.
To give the remnants more despair when they got into the Neo World program, Izuru Kamakura programmed the AI of Junko Enoshima into the AI of their long dead former friend and classmate - Chiaki Nanami. Everyone thinks of Chiaki as slightly suspicious, but they could never see her as the Mastermind, they see her only as this sweet girl who wants to be friends with everyone. However, Hajime's view changes when Chiaki obviously steers them off track in the fifth trial. Is Chiaki really what she seems, or is something darker hiding just below the surface?
