There is a youkai that has only been seen during winter.

A youkai that prefers cold places, Letty Whiterock is feared for ensnaring humans and freezing them, rendering them powerless to fight back.

To keep it simple, she is a type of Yuki-onna.

This youkai appears as a woman wearing light clothing that doesn't seem like it would protect her from the cold.

She appears during unusually cold days, though it is unknown whether the coldness is due to her appearance instead.

The extreme coldness might make you lose any will to fight(*1).

If caught by her tricks, it isn't an exaggeration to say that the fight is over before it even began.

It does not mean that she directly makes the wind blow and snow fall, but since she can enhance the winter that exists within nature, she can exhibit ridiculous powers which seem impossible for one youkai.

Despite being controlled by nature, her power is extremely strong.

After causing a thorough riot during winter, she suddenly disappears when spring comes.

It seems she hides somewhere until the next winter.

1: An example would be your not being able to get out of bed in the morning.

"I only see her on cold days." (Anonymous)

Probably because of such reasons, this youkai does not leave a good impression.

"When there is a snowstorm outside, I can't go outside because I'm afraid she might appear. However, my house is safe because it has good heating." (Owner of Kourindou)

I would advise that people go out only on clear days during winter, if possible.

However, if you shut yourself up in your house for a long time, the snow piled up on the roof will cause your house to collapse, so beware.

The thing called cold air is very troublesome. It is not a physically thrown cold object (*2), but something that lowers the temperature of the whole area.

Even healthy people can become sick. Even active people become inactive. They lose their fighting spirit.

There may be no way to completely avoid it.

First and foremost, wear warm clothes.

This is the most important thing.

It is enough if your body can move while you flee.

In particular, if the extremities of your body become cold, your circulation might worsen, so you should take care to eat well.

If you are careless and happen to see her while wearing light clothes, it is hopelessly difficult to escape, because the coldness extends for a wide range.

If you are not resistant to the cold, it is unlikely you will survive for long.

However, even though this youkai is fearsome, she only appears during winter.

When spring comes and it becomes warmer, there is nothing to fear.

If you find this youkai during summer, it might be your best chance to strike (*3).

2: Like from that of a certain fairy.

3: However, there has been no report of seeing her when it is not winter.
