Forced Shutdown

Forced Shutdown It is a system used to purge the "New World Program" as a last resort if anything were to go wrong. It will result in freeing all the students 'alive' in the game, but will be unable to ovewrite their memories with that of the memories from the game (thus, returning them back to what they were before entering the program). Makoto created this system just in case if something went wrong like Usami spreading despair instead of hope. It was programmed to be activated by atleast half of the class (8 students) by pressing both "Graduation" & "Retention" at the same time. Once activated, not even the teacher/AI in charge can stop it. It also acts as AI Junko's execution.

Execution
When the "Forced Shutdown" is activated, cracks began forming in the space. It soon shattered, revealing Usami in her Magical Girl form. AI Junko attempts to crush her with her right hand, but Usami dodged and pierced an electric spear on her hand. This causes AI Junko to be electricuted and caused her to drop her cellphone. AI Junko then tried to smash Usami again with her left hand, but Usami dodged & pierced her other hand with another electric spear. After being electricuted again, AI Junko can't move her hands since they're pinned down by the electric spears. Usami then used a colorful, sticky wipe which stuck to AI Junko's forehead. Usami then pulled AI Junko and causing her to smash her face on the ground & lose consciousness. Usami then kicked AI Junko on the forehead, causing her to regain consciousness and free her hands. But Usami began flying aroud AI Junko's body, leaving a rainbow trail. The rainbow trail then tighten, acting like a rope and constricting AI Enoshima. Usami then formed a rainbow circle with her wand, which was casting a spell. That spell caused the rainbow trail that was constricting AI Junko to glow. It then exploded, causing AI Junko to break into millions of cubes, thus 'killing' her. As AI Junko's body break apart in nothingness, Usami spins around into the air and exploded into millions of colorful hearts, as a sign that she has finished her job in stopping AI Junko and her love for her students.

Aftermath
After the Forced Shutdown succeed Makoto Naegi, Kyoko Kirigiri and Byakuya Togami left from the Island. And the remaining students vow to stay at the island as a requirement of the Forced Shutdown.
