The Spread Shot of Nue Houjuu from the world where a mysterious treasure ship flies through the skies (a Touhou LW original). She hurls completely unidentifiable lightning at her foes. "Nue" are a type of youkai that are often said to resemble raijuu. In fact, it's possible that all raijuu are nue. However, by their very nature, nue are unidentifiable. Debating what exactly nue are plays right into their hands.

The Focus Shot of Nue Houjuu from the world where a mysterious treasure ship flies through the skies (a Touhou LW original). She sends completely unidentifiable bird shadows to attack her foes. It's sometimes said that the strange birds that attacked the capital during the Heian era were actually nue, a type of youkai. Originally, "nue" referred to White's thrushes, and the mysterious youkai which came to be known as "nue" had no name. Since youkai come out at night, their true form is often unknown. If you yourself happen to see one, its appearance may well surprise you.

A Spell Card of Nue Houjuu from the world where a mysterious treasure ship flies through the skies. She sends colorful UFOs to attack. The UFOs are actually fragments of the Flying Storehouse that she renders unidentifiable with her Seeds of Unknown Form. However, when people in Gensokyo first saw mysterious things flying in the sky that they couldn't identify, they assumed they were UFOs. (It's actually surprising that so many of them knew about UFOs.) People really do see what they want to see―which works to the advantage of youkai, but is also somewhat disappointing.

A Spell Card of Nue Houjuu from the world where a mysterious treasure ship flies through the skies. She recalls her memories of being exterminated. In the past, there have been a handful of exterminations of nue and beings resembling nue. The records show the reasons for these exterminations were often rather loose claims that they were spreading misfortune or causing people to fall ill. However, that's only because little was written about youkai by future generations, who wanted to write extensively about the bravery of youkai exterminators instead. It's possible that youkai of the past possessed powerful enough magic to disrupt systems of government and enough raw firepower to level cities. If they were any weaker than that, the youkai exterminators wouldn't be so highly regarded.

The Last Word of Nue Houjuu from the world where a mysterious treasure ship flies through the skies (a Touhou LW original). She thrusts disorder upon an orderly civilization in this attack. During the Heian era, the beautiful, barriered-off Imperial capital sat on a grid. It was designed using the four cardinal points and became a symbol of the light of civilization and humanity's wisdom. It was a huge hindrance to youkai as well as an unpleasant place to be. Crucially, it stopped them from being able to enjoy the Night Parade with the humans. And so the nue, who despised highly organized structures, were called upon to attack it. The unidentifiable youkai couldn't wait to throw the city into chaos, and there was no one better than them to break through the city's barriers and do just that.
