Shirayuki Koyuki Species: Half-human, half-emperor penguin Gender: Female Age: 20 years old Height: About 140 cm A rare girl who carries the blood of both humans and emperor penguins. She is small and has a gentle personality. She is highly resistant to cold and prefers spending time on snow and ice. She can eat raw fish and sometimes takes naps on the ice. She has a black wolf cut with yellow-orange inner color and sleepy amber eyes. She wears sporty cold-weather clothing based on black, white, and yellow-orange tones. She is a bit shy and uncomfortable with sudden movements and loud noises. She keeps her distance from unfamiliar people, but treasures those she has recognized as companions. She not only enjoys being cared for but also looks after her companions and fusses over them. Though her appearance is close to human, her physical abilities and ecology strongly reflect emperor penguin traits.
