Кусакабе Юкі

A timid snow woman whose body is always cold. She will sometimes spread cold air while experiencing negative emotions and is susceptible to heat. She initially dislikes her demi nature, fearing that she could harm others, though Tetsuo manages to show her that the only things she can actually freeze are her tears and sweat. She's also secretly a manga enthusiast and has a taste for multiple genres.
