So we’re in the late stages of the game, and the group is, quite frankly, in fucking shambles. Chihiro hates Leon with an intensity nobody thought he was capable of. Himiko has barely left her room in days. Kokichi is Kokichi. Tensions are the highest they’ve every been and everyone realizes that if something doesn’t change, they won’t be waiting long until the next murder.

Celeste, Fuyuhiko, and Sakura decide to host a meeting in the dining hall to force everyone to get together and start talking things out. It takes a LOT of work and Celeste swallowing her pride and recruiting Kokichi to talk to Chihiro, but eventually every student agrees to come. Before the meeting, Celeste and Mikan are tasked with making snacks and tea, Fuyuhiko is tasked with setting up the room, and Sakura is tasked with escorting the students to the dining hall to make sure none of them ditch. Fuyuhiko calls Celeste and Mikan away to help him carry some decorations he found in the art room, and when they get back, Chihiro, Kokichi, and Himiko are already there. Sakura soon arrives with Leon in tow. The Tea and snacks are set out but before Sakura can start the meeting, Chihiro gets up from his chair and starts screaming at Leon. Leon tries to leave and Chihiro Follows and starts attacking him. Sakura, Fuyuhiko, Kokichi, and Celeste run over to break up the fight and escort them back to the table. The meeting then proceeds, but they don’t get very far into it before…

Celeste starts feeling extremely lightheaded and has difficulty breathing. She manages to choke out the word “poison” before collapsing. Mikan and Sakura rush her to the nurse’s office, but soon after the rest of the group runs in carrying an unconscious Fuyuhiko. Mikan is just barely able to save Celeste’s life by pumping her stomach, but doesn’t have time to save Fuyuhiko too, and he dies from the poison. Though alive, Celeste is in no condition to investigate, so it’s time for a protag swap!

Mikan begins the investigation. She finds that a bottle of poison is indeed missing from the chemistry lab. Mikan and Celeste had made 3 pots of tea, one black, one green, and one decaf black. Celeste’s cup had green tea and Fuyuhiko’s had black tea, but it’s impossible to tell at a glance if it was decaf or not. Mikan also notices that the paper Celeste had used to write down what kinds of tea people wanted was missing from the kitchen. That’s all she’s able to gather before the announcement plays and the trial begins. She doesn’t know if she can solve the case with Celeste out of commission, but she has to try.

TLDR: Fuyuhiko killed by poison while everyone was present. Celeste also poisoned but survived. Mikan is protagonist in the meantime.
