Ousama Game The Animation

Synopsis

It turns out the punishment text was for Masatoshi. Riona is furious at Nobuaki for his insensitivity. After 8 more hours however, Nobuaki tries the same trick by running the opposite direction, but the text was instead sent for Aimi who was grateful for Nobuaki's earlier actions and sacrificed herself by running the opposite way. Nobuaki reveals to Riona the conclusion of his first King's game where he and Chiemi were given an order to kill the person they love the most, and Chiemi had killed herself for Nobuaki to survive, and Nobuaki got a text from the King with the choice to either continue the game or get punished. Meanwhile, Natsuko reaches the summit first and uses various tactics to deter her incoming classmates Takuya, Yuuna, and Rina, resulting in their deaths. Nobuaki and Riona catch up with Ryou and Aya, and within minutes before the 8-hour mark, approach the summit but Natsuko stands in the way. With just 5 students remaining, can Nobuaki put a stop to the murderous King's Game once and for all?
