He is a tall, slender man with the Path of Piece necklace around his forehead and long white hair. He wears priest-like clothing.
During his brief appearance, he was shown to be a kindhearted person, always putting the needs of his subjects before his own and even remembering the names of many of them. He is shown to be too trustful and putting a lot of faith in people which led to many characters (namely Tatsumi) having an impression of him not being able to lead the organization properly. He has shown to be concerned about the welfare of people he had just met like Tatsumi and Mine, further affirming his image of a good but not capable leader.
The Lord was first shown during a speech, talking about how the citizens must not give in to despair and grief.
He was then shown wandering the outskirts of Kyoroch with a small group of bodyguards and followers. There, he first met Tatsumi and Mine, who were on a scouting mission. He told them not to fight but instead profess their love for each other, predicting their future relationship.
After Bolic was killed by Night Raid, He met Tatsumi & Mine again during their time in Kyoroch. He mentioned minor details surrounding the path of peace's origins. Soon after, The Lord launched the rebellion against the Empire.
According to Bolic and himself, the reason why he is able to gather so many people around him is his ability to see the future and his ability to heal others. While The Lord has said that he is "blessed" by god, it is later revealed that his abilities are in fact part of his Danger Beast heritage.
