『What Winter Left Behind』 Letty Whiterock (レティ・ホワイトロック Retī Howaitorokku) is a seasonal youkai who's only seen during winter. She seems fittingly cold towards most of the humans she meets, and is feared by humans as she is known to freeze them. She possesses an ability to manipulate chilliness. It's not an ability to create blizzards or make snow fall, but rather an ability to strengthen the "winter" that exists in the natural world. According to Perfect Memento in Strict Sense, since this is equivalent to an ability that manipulates the winter within nature, she possesses tremendous power according to the environment, but she is pretty much powerless outside of winter. By lowering the temperature, humans become less capable of activity, and lose their fighting spirit. Furthermore, since it's not a physical attack, it's impossible to completely avoid it, and it's not possible to take up any countermeasure except doing something to the extent of wearing thick clothing.
