Persona Q2: New Cinema Labyrinth Roundabout Special

Akemi Nakajima is a student in the "gifted class" in his high school. After being bullied and beaten by another student who a female student invoked, Nakajima uses his advanced computer skills to create the "Demon Summoning Program." He summons demons to attack the two, but he gets carried away and ultimately kills them. Now sick with the power of the demon realm Makai in his hands, he summons the demon lord Loki. Realizing summoning such a powerful demon was a mistake, Nakajima sets out to reverse the problem he has created by any means.

The story takes place on the last day of the Yasogami High culture festival. During the event, the heroes of Persona 4 see a strange bell tower appear on the school grounds. The heroes of Persona 3 also hear the bell, and are dragged into the future where the Persona 4 cast awaits. The two groups are locked in the school covered in Shadows, but meet two mysterious individuals named Zen and Rei, who have lost their memories. The cast soon learns that Zen and Rei's lost memories may be the key to solving the mystery of the bell tower's sudden appearance.
