The Spread Shot of Yuyuko Saigyouji from the world of heavy spring snows (a Touhou LW original). She loses herself to the spring temperament in this attack. Nobody really understood why Yuyuko caused the Spring Snow Incident. Even Youmu, her bodyguard-slash-gardener-slash-teacher, seemed to think it was just another one of her whims. Yuyuko is driven by feelings hidden so deeply inside her that they are a mystery perhaps even to herself. All that's known for certain is that she really wanted to meet Fujimi's daughter. But why?

The Focus Shot of Yuyuko Saigyouji from the world of heavy spring snows (a Touhou LW original). She absorbs her opponents' spring temperament and tempts them to die. Yuyuko has existed as a ghost for a thousand years, so it is almost impossible for an ordinary human to understand what goes through her mind. Perhaps she wanted a friend. But she already has Yukari. Maybe she wanted a family. But she already has Youmu. Then again, ghosts are former humans, and just like humans, their actions aren't always driven by wants or needs. The converse is also true. Sometimes they don't act even when they need to. Perhaps it really did all start as a simple whim.

A Spell Card of Yuyuko Saigyouji from the world of heavy spring snows. She loses herself to the spring temperament in this attack. Yuyuko no longer has her memories from when she was human, from when she was alive. Some believe she was the daughter of Saigyou, but then why is her last name Saigyouji? Perhaps she was the daughter of a different poet. The biggest problem with her being the daughter of Saigyou is that the dates don't line up with the secondary true data. Saigyou died 800 years ago, but Yuyuko is supposed to have been dead for a thousand years. Only Yukari, who knew Yuyuko from before she died, knows the truth. All that's really known about Yuyuko's father is that he was an incredibly gifted poet who happened across Gensokyo in his travels. From this, it can be inferred that he was quite an adventurous individual. Maybe he only called himself a poet to hide the fact that he was actually a professional youkai exterminator. That might help explain how the Saigyou Ayakashi, which was presumably growing somewhere in Gensokyo, ended up in Hakugyokurou's garden in the Netherworld after his death.

A Spell Card of Yuyuko Saigyouji from the world of heavy spring snows. She absorbs her opponent's spring temperament and tempts them to die. Perhaps it is Yuyuko's memories from when she was still alive that drive her to meet Fujimi's daughter. Yuyuko has the ability to tempt others to their death, which bears a stark resemblance to how the Saigyou Ayakashi's beauty once tempted countless people to lie down and die beneath its branches. Conversely, the record she found in Hakugyokurou's library that mentioned Fujimi's daughter tempted Yuyuko to live.

The Last Word of Yuyuko Saigyouji from the world of heavy spring snows (a Touhou LW original). She seeks the last sprinkling of spring in this attack. Yuyuko and the daughter of Fujimi are like Achilles and the tortoise. Given enough time, it feels like Yuyuko should be able to meet her, but she never will. Time, divided into infinitely smaller chunks, creates a singularity that wouldn't otherwise exist. Yuyuko is obsessed with gathering spring in order to meet Fujimi's daughter, but this obsession also brings her great joy that could potentially last forever. Her never-ending conceptual journey toward the Omega Point is not bound by constraints of time or space, meaning her hair can grow longer, and she can grow taller. The spring she has collected has become so dense that its gravitational pull has trapped Yuyuko in a dream, a delusion of distorted spacetime. The only way to free her is to fight against gravity itself.
