The younger of the two siblings. Gilson is a hyperactive and mischievous child who yearns for someone to play with, hence he attempts to get the monks to play with him, even if it means trouble for them. He befriends a stray dog to which he named Breeze. He has no knowledge of his mother being dead since his sister, Gami, could not bring herself to tell him. Although he is troublesome, he cares greatly for Gami, helping her to walk and bringing her food.
