King's Game

Ria calls Nami stupid for killing herself even though her punishment wasn't death. She repeats she is King, stating that since she made Nami touch her instead of letting her do it herself, it was not considered valid. However, Nobuaki still doesn't kill her. After tasing him, she scolds him for his lack of resolve, stating she isn't actually king but wants to enjoy the King's Game, which will be difficult to do if Nobuaki is so boring, and beat the King. Later, his classmate Yousuke begins doing research and finds information about the King's game, including the fact each classmate got a one-character text from the King before their death, and that the game was played 30 years ago in a village called Yonaki. Yousuke then dies, amongst almost half the class who broke the latest rule to not to do anything 'unnecessary', which was crying, deduced by Nobuaki. While waiting for the train to the village, Nobuaki gets hit in the head, and wakes up in a room with his hands tied. Kaori accuses Nobuaki of being the King and killing Yousuke. Nobuaki explains the situation and tells Kaori Yousuke likes her and he told Nobuaki to protect her if anything happened to him. His words cause Kaori to cry and she dies for breaking the rule.
