One month has passed since the conclusion of the Treasure Hunt Game. Kaname has formed his own clan and is undergoing training at Danjo Boxing Club. Danjo, who is the leader of the boxing club, challenges Kaname to a no-holds-barred Vale Tudo style match to gauge Kaname’s training progress and to decide if he is a worthy partner to form an alliance. Kaname stands his ground and unflinchingly battles Danjo, who is one of the top fighters in Darwin’s Game. Just as the battle is about to reach its climax, they are interrupted by the sudden appearance of an unexpected figure.
