『Dot』 Nico's older brother / (21 years old) - 181cm A demon male with a pair of horns of different thickness and size on his forehead, and long black hair in a pomade-style ponytail. He can manifest two extra arms from his back that resemble bird legs. Because he is worried about Nico getting hurt by the horns, he wears specially made goggles where the larger horn fits into the frame and the smaller, broken horn is covered by the lens. He is traveling with his younger brother Nico for a specific purpose. He is a brother who feels proud watching Nico grow, and he affectionately calls Nico's wings 'flappers'.

『Nico』 Dot's younger brother / (8 years old) - 130cm A boy with white hair that is messy in places, a hairstyle where eyes are linked together like two braided strands, and white wings. Since he is still young and finds it difficult to retract them at will, he usually carries his wings tucked inside his backpack. He admires his brother Dot and is an innocent, active child who wants to copy everything his brother does, but he is clumsy and makes frequent mistakes. He is shy around strangers.

『Mim』 Dot's old rival-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 military partner in the past. Currently retired, he runs a private general store as a tailor and makes clothes. His right leg is infested with mycelium and is slowly crystallizing, possibly due to an injury sustained during his military 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.
