Naegi catches Oogami Sakura fighting with Monobear, leading him to suspect she’s the mastermind’s agent. The fourth floor contains the chem lab, music room, data processing room and principal’s office, but the latter two are locked, and Monobear creates a new rule prohibiting breaking down locked doors. Fujisaki’s Alter Ego AI discovers new facts about Hope’s Peak Academy, including a past incident that led to the plan to incarcerate students executed by the principal.
Monobear announces Oogami was his agent, causing strife amongst the students and leading to a fight between Asahina and Fukawa. Later, Alter Ego tells Naegi and Kirigiri he wants to fight with them; they connect him to the network in the hidden room. Later, they and Asahina find Oogami locked in the Rec Room. Naegi breaks the window to unloc the door, and they discover Oogami is dead. Asahina believes the culprit could only be Togami, Fukawa, or Hagakure.
This was a hefty episode with a lot going on, hence the long synopsis. Not only is progress made in discovering who’s behind all this in the first place (thanks to Alter Ego), Monobear’s mole is revealed, and turns out to be the person we least suspected (other than Naegi). In order to ensure the safety of certain unnamed hostages, Oogami was to kill someone if there was ever a lull in the killing. But with a steady pace of murders more than half the student body is gone, and Oogami must have had enough to decide to turn on her master.
At first we were wondering why Monobear was being so lenient with her (Junko met a sticky end for opposing him, after all), but then it’s clear he turns her into a catalyst for more murder by outing her. The Togami/Fukawa/Hagakure alliance clashes with the Oogami’s loyal friend Asahina, with the calm, logical Naegi and Kirigiri in the middle. Oogami ends up dead in a classic locked-room murder mystery. As usual, while there’s a list of obvious potential culprits, Oogami’s actual killer may well be none of them.
