After living for long time in the city, yukkuri has evolved. They learned how to survive in the street, but forgotten about life in the wild.
Snow rarely falls and there's always food source in form of human's garbage. This means the stray yukkuri never need to spend their winter in hiding.
Marisa and Reimu hide inside their cardboard house. Inside, pages from old newspaper are scattered, but it's not enough to protect them from the cold brought by snow. Both of them starts rubbing each others until Marisa told Reimu to stop.
Other than rub rub, there's another way for yukkuri to keep themselves warm, that is with food. But again, Marisa told Reimu to hold from eating their food supply. They don't know how long they will be trapped in their home.
Marisa is a smart yukkuri, but other families are not so lucky.
In one house, a Marisa and Alice pair rubbed each others for too long and can't hold back from refreshing. With babies, they know only death awaits them.
In another house, a Marisa and Patchouli pair also refreshed, much to Patchouli's unamusement. But that's not all. The excreted liquid quickly rob away heat and freeze them.
In another house, a Deibu has eaten all the food supply and force her husband to go hunting, which of course means death.
Yet in another house, a Chen and Ran pair has been prepared, but the weight of snow crushed their house and killed them both.
Marisa and Reimu's house is luckily build under human's roof, protecting them from snow.
The next day, snow finally stopped. The warmth of sun is source of joy to those who had withstand the cold, the hunger, and their brutal wives.
Quickly, a Myon jumps out, only to be trapped in the 7cm thick snow.
A Marisa is smarter, she used her hat to row out of the snow. But you can only see her move if you keep watching closely. It's that slow.
Marisa know the danger and still await, holding back her wife and the hunger looming over them.
Besides, the smarter yukkuri has seen how the melting snow is not fun even for human.
When activity increases, human cleaned the snow from the street and those big suii that brings death to yukkuri also cleaned snow from the street.
Another Marisa went to hunt, but as she returned, her feet is disabled by water from the melting snow. Only death awaits for her now.
Finally, after another day, Marisa walks out of her house with Reimu. They will go to the hunting ground now.
Reimu is so hungry, she almost ate the snow. This is also a bad thing, Marisa knows. Snow will rob away their body temperature and the large intake of water will cause diarhea. Even healthy adult yukkuri would be in trouble with that.
Reimu told Marisa something strange. They can move like Suii.
Marisa tried, and they moved quickly on the street. But unfortunately, they can't turn and both crashed on the wall. Luckily, the snow cushioned their crash.
This is when Marisa and Reimu realized their feet are injured.
The water is frozen last night, making the street into a skating rink. But the ice is thin, and in many places, sharp surface of the ashpalt is pointing out. Marisa and Reimu slide quickly on that and grated their own feet. They never realized this because their feet are numb because of the cold.
They know they're in trouble, so now they have to move to get food and rest to recover. Stray yukkuri can't survive with injured feet.
They hold their pain and move slowly. Because of the coldness, paste doesn't leak out from their wounds.
There's a rumbling voice. Reimu doesn't know what it is, but Marisa who's experienced in hunting know it very well. It's a big Suii!
With injured feet, there's not much they can do. Marisa watched as suddenly, Reimu is replaced by a black blotch on the street.
Recovering from her sadness, Marisa continued to the garbage site. She's ready to break taboo now.
There's unwritten rule among city yukkuri about hunting ground. First, they must not scatter the garbage around. They must not make noise and no fighting in the hunting ground. This is because if human founds out, then all the yukkuri who hunts there will lost their hunting ground or even got killed.
Of course, eating on the hunting ground is also forbidden. But Marisa need food to recover herself, she can't wait anymore.
Unfortunately, the garbage site is empty. Unlike usually, the residents here starts obeying the garbage pickup schedule and thus there's no food today.
Marisa gave up and crawl back to her house. But the ice is melting, can she even reached her house ?
The next day, a plastic bag with Marisa in it is buried under other plastic bags. It's the burnable trash day.
