『Dot』 Nico's older brother / (21 years old) - 181cm A demon male with long black hair in a pompadour ponytail and a pair of horns on his forehead of different thickness and size. He can manifest two extra arms from his back that resemble bird legs. Out of concern for Nico's safety, he wears specially made goggles: the frame fits over his large horn, while the lens covers the broken smaller horn. He is traveling with his younger brother, Nico, for a specific purpose. He is a doting older brother who watches Nico grow with pride, affectionately calling Nico's wings "flappers."

『Nico』 Dot's younger brother / (8 years old) - 130cm A boy with white hair that sticks out in places, a unique hairstyle where his eyes seem to trail down like twin braids, and white wings. Because he is still young and finds it difficult to retract them at will, he usually keeps his wings tucked inside his backpack. An innocent and energetic child who admires his brother Dot and wants to copy everything he does, though he is clumsy and prone to mistakes. He is shy around strangers.

『Mim』 Dot's old rival and friend / (21 years old) - 198cm He has lime-green hair, a single small horn, squinting eyes, a monocle, and speaks with a dialect. He was Dot's partner in the military. Now retired, he works as a tailor running a private general store where he makes clothes. His right leg is infested with mycelium and is slowly crystallizing, likely due to an injury sustained during his service. He can manifest arms from his back that resemble insect skeletons. He prefers his black tea hot and without sugar. His room is filled with books, including travel magazines.
