(Not) Normal Arc: Kill and Live.After learning from Monokuma about the faulty door on his bedroom's shower room, Makoto is approached by Sayaka, who states she is afraid that someone may be after her, and offers to switch rooms with her to put her at ease. The next day, however, Makoto is horrified to discover Sayaka lying dead in his shower room, stabbed in the stomach with a kitchen knife. As Makoto becomes angered by this tragic turn of events, Monokuma explains that one of the students is responsible for her murder and they must judge for themselves who the killer is in a "class trial". If the class can successfully determine the guilty party, that person alone will be executed, but if they guess wrong, the killer will be set free and everyone else will be put to death. When fashionista Junko Enoshima voices her objection and assaults Monokuma, she is impaled to death by spears as punishment, warning the other students what will happen if they don't follow the rules. After the students' electronic handbooks are updated with details about the murder, Makoto is immediately made a prime suspect when it is shown Sayaka had died in his room. The students begin their investigation, making notes of all the evidence they find, including a message written in Sayaka's blood reading "11037". Before the trial begins, Makoto finds Sayaka's motivational DVD, which reveals that her fellow members in an idol group were all killed by Monokuma, who would only explain why if she managed to graduate. As the students head for the courtroom, Makoto receives cryptic words of advice from the mysterious Kyoko Kirigiri.
