The "Leftover of Winter". Stage 1 boss of Touhou's Perfect Cherry Blossom.
A seasonal yuki onna in control of cold, leading to her doujin portrayal as friends with Cirno. She is only visible during winter, but her status on other times of the year is debatable (either she melts or hibernates somewhere). She is infamous, however, for her large hit box, which led to jokes about her being fat. This has lead to pictures of her with a curvy or plump figure with large breasts.
