Ep. 11: Nobuaki confronts Natsuko while revealing past King's Game trauma and Aimi's sacrifice.
Aired on December 14, 2017

The punishment message was intended for Masatoshi, leaving Riona angry at Nobuaki’s insensitivity. Nobuaki attempts a diversion by running in the opposite direction, but the text actually targets Aimi, who sacrifices herself to save him. Nobuaki then shares a dark secret from his first King's Game: he and Chiemi were ordered to kill their loved ones, and she killed herself so he could survive, leaving him with a choice from the King. Meanwhile, Natsuko reaches the summit first and kills Takuya, Yuuna, and Rina using various tactics. As the eight-hour mark approaches, Nobuaki and Riona join Ryou and Aya at the summit, where Natsuko blocks their path. With only five students left, the group faces a final confrontation to end the deadly game.
