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 has a childish side which was made evident when he became giddy over the ship ride to Cal Mira Archipelago. He has a habit of calling the younger persons "Kiddo." He has high morals and doesn't want to hurt anyone who is irrelevant to his mission. He is charismatic enough to attract good people to his side.
