L'arc has spiked red hair and is muscular. He has a tattoo of a scythe on his upper arm and appears to be handsome

He is carefree and laid back, taking a very relaxed path to every problem. He is, according to Naofumi, an older-brother kind of character. Even though he has become a king, he likes his freedom. Just like Glass, he has a warrior spirit which is shown during his fight with Naofumi.

He is a good judge of character just by looking at someone. He did have a childish side which shown by the way, when he acted too excited for the ship ride to Cal Mira island. He had the habit of calling the younger persons "Kiddo". He has high morals and doesn't want to hurt any others who are irrelevant to his mission.
