Grand Magic Games arc
When the Fairy Tail Rescue Team finds Arcadios lying injured on the ground, Kama surrounds them with his fellow executors. As his team attacks the Fairy Tail Mages, Kama simply watches until everyone ends up separated because of the explosion that occurred when Grow Flow was destroyed. Kama ends up with Natsu Dragneel who he proceeds to fight saying that he will execute him for his sins. Unleashing his scythes, Kama immediately attacks Natsu with fast slashes aiming for his neck, Natsu then quickly dodges them and when he finds an opening, grabs one of Kama's scythes and destroys it.

Kama is surprised and is eventually disarmed by Natsu making him defenseless. Natsu continually punches Kama with no chances of a counterattack. With his back to the wall, Kama questions Natsu whether he understands that his actions will subject him as an enemy of the Kingdom Of Fiore but a furious Natsu finishes him stating that for the sake of his friends and family he is willed to view anyone his enemy. Natsu lands a flaming punch on him as Kama bursts through the wall ending in with the same place where his other fellow executioners lie unconscious around him, defeated. Natsu asks Kama where the exit is located otherwise he will be the one who will "execute" him.

A while later, Kama and the rest of his partners manage to recover from their battle, and together head out to continue their mission and locate Natsu and his group. Finding the Fairy Tail Mages battling the Royal Army whilst trying to escape Mercurius in the underground passages of the castle, Kama approaches Natsu, stating that whilst he understands Natsu's philosophies, he wants his own to be understood too. Out-rightly stating that he will never let sinners escape the kingdom, Kama is met with Natsu's angry response. With the battle looking in favor of the Kingdom of Fiore, Kama tells Natsu and his friends to surrender. However this advantage is short lived as the shadow under Uosuke begins to grow. The shadow then consumes the Royal Army and Garou Knights in the blind confusion of the moment, leaving only the Fairy Tail Mages in the tunnels.

After the Dragon crisis is dealt with and left in the past, the King organizes a ball at the palace, for all the Mages who helped hold off the Dragons to enjoy. Kama, along with his team's members, appears to be alive and well, as when Natsu appears wearing the King's attire, Arcadios orders them to stop him. However, Kama tells Arcadios that they are no match for Natsu.

Magic and Abilities
Expert Scythe Specialist: While described as possessing a form of Magic thought for killing efficiently, Kama has only been shown employing his two scythes during his battle with Natsu Dragneel, demonstrating remarkable ability in swinging them despite their massive size, and, true to his beliefs, aiming for his foe's neck with great accuracy despite the sheer speed of his slashes.

Enhanced Strength: Kama has displayed a high degree of physical strength, being capable of effortlessly swinging around each of his large scythes with a single hand. The attacks he performs with these very same weapons are shown to be powerful enough to cut solid stone, slicing cleanly through pillars and walls without losing their momentum.

Enhanced Durability: Kama appears to be considerably durable, being struck by Natsu's Fire Dragon's Iron Fist and sent crashing through a stone wall (which was reduced to pieces in the process) only to emerge seemingly unscathed afterwards, merely displaying shock at his opponent's will to make an enemy of the Kingdom. He was also the only member of his group to remain awake after his defeat, which had him sent crashing through yet another stone wall.

Equipment
Double Scythes: Kama carries around two identical scythes with peculiar hand-like extensions from the opposite side of the blade. He carries these on his back with the handles crossed and are deadly in their own right. In the anime, these weapons also possess Magical abilities, being used to mark a target with purple handprints and allowing the scythes to follow them.
 * Guillotine Justice: Kama joins his scythes in a manner opposite to each other, causing the weapons to act in a propeller-like fashion, continuously spinning at great speed that proceeds to rush to the marked target.
