King's Game: The Animation - S01

Transferring to a new school is hard enough, but Nobuaki Kanazawa isn’t interested in making friends. His antisocial attitude makes sense when his class gets a text from someone called "The King," announcing the start of the "King's Game." Everyone has to follow the orders given-failure to comply, quitting, or ignoring a command within 24 hours means death. Nobuaki has played this game before and watched people die. He tries to warn his classmates, but they don’t listen until the first victims fall. Trapped in a nightmare with no way out, Nobuaki faces a grim choice: save himself at the cost of others, or try to protect his classmates like he couldn’t the last time.
