Years have flown by since the catastrophic event masterminded by the sinister Junko, a tragedy that left Chisa grappling with the heart-wrenching loss of nearly all her students. In the aftermath of this devastation, she sought solace within the Future Foundation, clawing her way up the ranks to become the formidable leader of the 5th Division. Her mission was both clear and daunting: to confront the ominous force known as Despair. Yet, unbeknownst to her allies, Chisa had become ensnared in a treacherous web of manipulation, tragically morphing into the Ultimate Despair, a sleeper agent for the true harbinger of chaos, playing a crucial role in the unfolding disaster. The narrative took a breathtaking turn when the Class 78th emerged from the brutal killing game, led by the indomitable Makoto, who rallied the shattered remnants to confront and dismantle Junko Enoshima's reign of terror. In a stunning display of unity, he even managed to sway Junko's own sister, Mukuro, to betray her bloodline. Yet, a chilling question loomed: what fate awaited Mukuro? Many within the Foundation clamored for her execution, but Makoto, with unwavering conviction, championed her redemption. Instead of death, they concocted a daring plan to imprison Mukuro, compelling her to assist in the restoration of a fractured world and to hunt down Chisa's students, the remnants of despair. But Chisa herself was still covertly working for the Ultimate Despair; the malevolent Monaca, a student of Junko, had ordered Chisa to sabotage the Future Foundation, twisting Kyosuke into a monstrous figure, and plotting to eliminate both Makoto and Mukuro before they could unravel her sinister plans. Now, Chisa finds herself ensconced in her office, buried beneath a mountain of paperwork, her mind a battlefield of conflicting loyalties and the haunting specter of her past.
