The gang overpowers Natsuko and reach the summit, just as they get their next order to cut their body parts to make a human doll. Ryou offers to sacrifice first so Natsuko helps him cut his leg using a chainsaw. Seeing Ryou dead, Aya tries to strangle Natsuko but Natsuko just cuts her body off with her chainsaw. With only Nobuaki, Riona, and Natsuko remaining, they finally calm down to brainstorm how to end the game once and for all. They combine the one-letter texts from the dead classmates and finally discover the truth about the King's Game: It is, in fact, an apocalyptic virus-type of game that would never end until all of humanity is destroyed. Even offering up all of their lives to end the game wouldn't matter because it will get the same result. Natsuko tries to kill Nobuaki by strangling him for confirming her suspicions of him giving everyone false hope, but Riona attacks Natsuko with the chainsaw and fatally wounds her. With Natsuko seemingly dead, Riona begins declaring her love for Nobuaki but using the last of her breath, Natsuko kills Nobuaki with the chainsaw, claiming she loved Nobuaki first and refusing to let Riona take him. As the only surviving classmate, Riona drags Nobuaki's corpse to the beach and implicitly commits suicide by drowning herself along with Nobuaki's dead body. In the end, all 32 students have succumbed to death due to the apocalyptic virus known as... The King's Game. In the epilogue, somewhere in Japan, a random student gets a text from the King, saying the King's Game has begun once again.
