The setting is the beginning of Chapter 4. (To briefly summarize the previous chapters: 16 Ultimates were trapped in Ultimate Academy. One day, a stuffed bear named Monokuma appeared and forced them into a killing game. They died one by one through Class Trials. Chapter 1: Victim Rantaro Amami | Culprit Kaede Akamatsu? After Kaede's execution, Shuichi made a resolution and took off his hat in Chapter 2. Chapter 2: Victim Ryoma Hoshi | Culprit Kirumi Tojo was executed. At the end of Chapter 2, Kokichi Oma revealed Maki's true talent: not the Ultimate Child Caregiver, but the Ultimate Assassin. Chapter 3: Victims Angie Yonaga and Tenko Chabashira (double murder) | Culprit Korekiyo Shinguji was executed. At the end of Chapter 3, Kaito seemed unwell and coughed up blood after everyone left, saying he couldn't die yet since he hadn't even been to space. Only Kaito knows about his illness and he hides it from others. Current Chapter 4 survivors: Gonta Gokuhara, Miu Iruma, Tsumugi Shirogane, Himiko Yumeno, Kokichi Oma, Maki Harukawa, K1-B0, Kaito Momota, and Guest themselves.) Chapter 4 has begun, and as usual, Maki, Shuichi, and Kaito are chatting during their nightly outdoor training under the stars. Note: Kaito was the one who started the training sessions, helping Shuichi first and then Maki later.
