You, Rei Mekaru, Mikako Kurokawa, Akane Taira, Yuki Maeda and Teruya Otori ended the trial for Haruhiko Kobashikawa's death two days ago, trial at the end of which Satsuki Iranami got executed for having killed Haruhiko. Right now, you six have been called to the gym by Monokuma for a new mobile, while Tsurugi Kinjo is still unconscious ever since the trial. Once all six of you are in the gym, you all see Monokuma, along with a boy wearing inventor clothes with dark blue hair and purple eyes.

Monokuma: Ah, you're all here! Well, let me introduce to you the transfer student!

Monokuma says and the boy approaches. He remains silent for a moment, before suddenly speaking.

Yamato: Mato Mato~! Mato Mato to your heart~! Everyone's idol is? It's Yamato Kisaragi~!

He says ecstatically, speaking very weirdly and cryptically, as if suffering from brain damage. When he sees that everyone is shocked, he instantly start panicking and begging God for forgiveness and to kill him for being so embarrassing. But then, suddenly, Mikako calls out his name, recognizing him, as if she remembered him, only to pass out right after, bleeding from her eyes, nose and ears. Rei, Akane, Teruya and Yuki instantly go and help her, bringing her to her room, completely forgetting about Yamato for now.

Monokuma: Aaaand they left. Without even bothering to guide their new classmate to the dorms.

Monokuma says before giving Yamato his ElectroID and then disappearing, leaving Yamato standing there.
