Great Fight Festival arc
Upon accepting the invitation of participating the Great Fight Festival perpetuated by the two members of the Ten Commandments at Vaizel, three elite members of the Assassin Knights entered the Labyrinth where they encountered an Earth Crawler within the depths of the maze they explored and managed to kill the humungous formidable creature with powerful poisons from the tips of their weapons that slowly suffered and died from its effects before continuing on the path for their wish to be fulfilled.

After managing to reach their main destination and exiting the deadly maze, the Assassin Knights met up with several new contestants and some of them are notably Hendrickson, Slader, Griamore and Matrona in front of the pleased hosts of the festivities. Later on, they witnessed the huge gaping hole created by the combined strengths of Meliodas and Ban in a successful attempt to force their way through the walls of the Labyrinth where they met up with their companions along the way.
