That same day the students find a victim in Makoto's room in the shower room: Yasuhiro Hagakure, with a knife in his stomach. This is also identical to the first case murder of the actual game.
Makoto begins investigate in his room and the murder scene in order to gather clues and evidence while also asking other students. Not too much later, Monokuma announces that they all need to meet up for the Class Trial in order to find Yasuhiro's murderer. In a similar fashion to the first case of the game (albeit very condensed and not as detailed) it's pointed out how clean the room is as the killer must of used a lint roller, and on the aforementioned lint roller is potato chip grease. Hifumi Yamada is accused of being the Blackened due to this, which he later breaks down and admits to. The students vote correctly for him, after which he goes through his execution: "Kiwotsukete, Buko-hime! Dai Kaijū Shinkō!!".
- Hifumi is the only character to have an Execution shown outside the artbook that wasn't in any of the games.
- Differences from the playable "Trial Version":
- The "Demo" doesn't stop in the middle of the trial, as it does in the playable Trial Version, and instead continues proceeding up until after the execution.
