An unknowing Sudou Kaname is invited to try out a new mysterious mobile app game called Darwin's Game, but later realizes that he's in for more than he's bargained for when he finds out that there's no way to quit the game.

Darwin's Game focuses on 17-year old Kaname Sudou, who accepts an online invitation from a friend to play a mobile game called Darwin's Game. He had no idea that the game involves a fight between the two players and you might actually die both in the game and in real life. To win the fight, players are given a Sigil, an evolutionary ability that varies from player to player and only the most skillful players will be able to clear the game and survive. Kaname determines to clear the game, find the creators of the game and take revenge upon them.—Scientiiaa
