Daisy Bellefort's eldest son. He has the same ability to use teleportation magic as his mother and father. He has taken care of his father since he was alive. After his father died, he helped protect the city in his father's place, and protected his mother and younger sister, Celine Bellefort. Until his younger sister was 10 years old, she told him that she wanted to help lighten Brian's burden, so please teach her swordsmanship. After that, he taught his younger sister swordsmanship and fighting skills. When she was able to train by herself, his younger sister began to train much better than the average child, and often helped deal with bandits and monsters that disturbed the city. He studied at a large school in Bellefort, and was often targeted by girls in the school. The school's name was Bellede, and when his younger sister was 15 years old, she also enrolled there.
