Shortly after an investigation of the murder scene, the school trial begins to find Kiyotaka Ishimaru's and Hifumi Yamada's murderer. Yasuhiro Hagakure is the main suspect of this trial, because of Hifumi's dying words: "Yasuhiro", which is obviously his name, and so mostly everyone thinks it can only mean that Hifumi was killed by him. The 'Robo Justice' outfit also fits better on him than on anyone else, and it only adds to an increasing suspicion of him being the culprit.
After more discussion, Celestia Ludenberg is decided as the culprit. She denies it, but the students find some evidence that strongly suggests that she is the one responsible for Hifumi's death, and the one who planned out Taka's death for him. Hifumi was her accomplice, but was later murdered by her shortly after him murdering Taka.
Celeste tricked him into thinking that Taka had stolen Alter Ego from the locker room, but was actually stolen by Celeste herself, and all went according to her plan. It is also revealed that her real name is actually Taeko Yasuhiro, and she murdered Hifumi only because she wanted her dream to come true: to own and live in a castle with servants attending to her every needs, and the 10 billion yen Monokuma offered as a reward for graduating could be used to increase her chances of her dream coming true.
The episode ends with Kyoko and Makoto Naegi conversing with each other: Makoto asking her why she doesn't trust him if they're friends. Kyoko says that she'll try to trust him, and then tells him of a secret room in the boy's restroom in the second floor, and that there are no cameras in there. Makoto goes to investigate, and finds a book with a note in it that says: "We must not leave this place." He is then caught off guard and attacked by a mysterious masked person. After being knocked unconscious, he wakes up and find the bookshelf he got the book from, empty.Then, he opened a door only to find Monokuma and Sakura Ogami both with shining eyes, most likely talking about something.
