Years had passed since the devastating calamity instigated by Junko, yet its echoes still reverberated through the halls of Monaca Elementary. Junko had infiltrated the classroom, cloaked in an aura of warmth and affection, skillfully weaving a web of manipulation that led to the formation of the Warriors of Hope, with Monaca at the helm. Aware of Junko's ulterior motives, Monaca played her part, leveraging her position as a representative of the Towa Group to assist in the mass production of Monokumas for the impending tragedy.

Deceptively, she spun tales to her father and the other adults, claiming her ambition was to develop advanced robots designed for domestic assistance and emergency response. Her family's detachment, coupled with her brilliance, granted her the freedom to pursue her ambitions, provided she delivered profits without probing too deeply into her schemes. The Monokuma Units birthed by the Towa Group transformed into ruthless instruments of destruction during the tragedy.

In a sinister twist, Monaca also began crafting Monokuma-themed helmets capable of brainwashing their wearers into obedient pawns, thus birthing the Monokuma Kids. Even after Junko's demise, Nagisa, Masaru, Jataro, and Kotoko found themselves adrift, uncertain of their next steps. Junko had instilled in them the vision of a utopia for children, one that required the eradication of all adults—whom she labeled "the Demons." Monaca, ever the manipulator, urged them to cling to hope and to carry forth Junko's legacy, further twisting their minds by claiming that the vile Demons were responsible for their beloved "big sis Junko's" death.

In a calculated move, they captured Nagito, designating him as the Servant, while Monaca conspired with him to transform Makoto's sister, Komaru, into the next incarnation of Junko Enoshima. Now, Monaca Towa sat in her electric wheelchair, flanked by her loyal followers, as they deliberated the fate of Komaru, the air thick with tension and anticipation.
