Prologue
When Kyoko woke up, she went to the elevator area to find Mahiru, Shuichi, and Venti where she introduced her name but not her ultimate as she didn't wish to share it with others. As the other members of the group came and as they all went to find Kiibo, Makoto, and Komaru, they all decided to go to the stairs but not before getting Shuichi from the elevator area to console him and guide him to the staircase. They go downstairs to find Peko and Rantaro where they find out the cruise was government sponsored. While she went with the others to the elevator, she warns them that this cruise was not as it seems and they should be more aware. They descend to find a island, in which they split up into pairs. She goes with Rantaro as they both discuss on why she hides her ultimate and discussing on how this cruise might turn out. When they all wake up to the beach after being knocked out, they talk about their findings before finding out that the cruise was more of a killing game. After asking questions, she texts Rantaro and finds out he has a plan but he can't say for undisclosed reasons. She wishes him well in the texts before going to him and Shuichi. The three discover that Shuichi found a door that was locked and they decide to observe the door. They meet up with peko, in which the four decides that they have to be aware of everyone no matter what and to be careful in this game. After that, the curfew is announced and the four head to their dorms to go sleep.
