Set one year after the end of Persona 4, Naoto is asked to investigate the mysterious disappearances of two Yagakoro students by an old detective friend, Touko Aoi. There, she is partnered with Sousei Kurogami, a mechanical detective and a polar opposite to her in terms of personality and methodology. In their first encounter, she awakens to a new persona Amatsu Mikaboshi, which enables her to amplify Sousei's Persona ability, Tsukuyomi. Together with Sousei, she discovers the Midnight Site, an anonymous site where judgement is passed on others by five judges named after figures in Japanese mythology-- Uzume, Sarutahiko, Omoikane, Tajikarao, and Futotama.
However, it quickly becomes apparent that this case and another under Touko's supervision are related when one of the five judges turns up dead with ballistics pointing to a missing police officer's gun. Naoto and the others must discover the identity of the other judges to protect them and find out the culprit who seeks to kill them.
- Before Persona 4 Arena Ultimax was released, the novel was part of the continuity. However, due to mixed-to-negative reception in Japan the novel was thrown out of continuity when Persona 4 Arena Ultimax was released.
