The Spread Shot of Yukari Yakumo from the world with a never-ending winter (a Touhou LW original). She attacks with blue bullets and purple bullets. Originally, there were no distinct boundaries for the yearly cycle of climate variations local to a region. However, that was inconvenient, so people made a calendar that marked four extreme points (the spring equinox, the summer solstice, the autumn equinox, and the winter solstice) and then split the year into four seasons with specific days that marked the start of each season. Spring, summer, autumn, and winter are the four seasons, and they are separated by the last day of one season (in Japan, this day is called setsubun) and the first day of the next.

The Focus Shot of Yukari Yakumo from the world with a never-ending winter (a Touhou LW original). She attacks with green bullets and blue bullets. "This world" is the world of the living, the real world where people live. And the Netherworld is the world of the afterlife. According to various mythologies all around the globe, back when the world was still new, there was no separation between the living and the dead. There are records that state it was possible to walk from the world of the living to the Netherworld. There is a theory that the custom of stacking stones came about because people wanted to create a boundary between life and death. The weight of the stones would seal the dead who were buried underground.

A Spell Card of Yukari Yakumo from the world with a never-ending winter. In this attack, she makes her opponents realize that humans have entered the domain of youkai. During our world's Spring Snow Incident, Yukari informed Reimu of two things. First, the boundary between humans and youkai in Hakugyokurou had become less distinct. Second, Reimu, who had come to the Netherworld, had left the side of humanity. In Gensokyo, the humans and youkai maintain a relationship where they affect each other in important ways, and it is also taboo for a human to become a youkai.

A Spell Card of Yukari Yakumo from the world with a never-ending winter. More bullets are added as time passes in this attack. There are two things that come to mind when talking about standing on the edge of life and death. Yukari's best friend, the ghost Yuyuko Saigyouji and the situation that arises during battles of bullets. In battles of bullets, the combatants brush with danger at every turn until they experience the patterns and understand the route they must take. They are serious battles where life and death are separated by the thinnest of margins, and it is almost like the combatants breathe in sync with one another. You could call them the ultimate game.

The Last Word of Yukari Yakumo from the world with a never-ending winter (a Touhou LW original). This is the Last Word Yukari prepared for herself during the extended Spring Snow Incident. Apparently, she was planning to use other patterns if the incident was resolved quickly. This attack combines two blizzards that should be fleeting and rarely coincide... The blizzard of snow that covers Gensokyo and the blizzard of petals that decorates the Netherworld. Only a youkai who can manipulate barriers could harmonize them both to create such beauty. This spectacle looks like fantasy, not reality.
