Remembering the melancholy of human existence. Even ghosts stray from the path of righteousness.
~ Yuyuko Saigyouji

Yuyuko Saigyouji is a character from Touhou Project who debuted as the final boss of Perfect Cherry Blossom. She is the ghost princess of Hakugyokurou, the netherworld of the "formerly-living", but was once a living human. Long ago, after her death from suicide, her body was used to place a seal on the Saigyou Ayakashi, a dangerous youkai cherry tree, to stop it from killing innocent humans. She has the power to invite mortal souls to death, and those souls who perish this way wind up in Hakugyokurou rather than Heaven or Hell. Though it might seem dangerous for such a whimsical, seemingly impulsive personality to wield such a terrible power, Yuyuko appears to have a strong sense of responsibility regarding her power, and never uses it recklessly or out of spite, nor does she use it as a weapon. Ironically, it was this power that drove her to kill herself in the first place. Humans fear Yuyuko because of her fearsome power and a general fear of the supernatural, but she is very cheerful and friendly. Unlike many ghosts, she resembles a living human, and her playful, good-humored personality, otherworldly beauty, and courtesan charm can have a disarming effect. She often makes bizarre and apparently nonsensical remarks and sometimes seems to overlook the obvious, leading to her characterization as an airhead or a ditz. However, at other times, she will reveal an extremely cunning and perceptive side and will also sometimes display an extraordinary level of knowledge. She seems to never take anything too seriously, though, and she loves to tease her straight-laced and eager-to-please assistant, Youmu, who is her opposite in many ways. Probably originating from the term "hungry ghost", she is also known for her incredible appetite and seems to have a food-related metaphor for any situation. Yuyuko is truly "dead and loving it."


During the events of Perfect Cherry Blossom, she enlisted Youmu to find a way to make the tree bloom to resurrect the corpse buried beneath it, apparently unaware that it was her own body. Forced to abandon her plan, as it would only result in her own destruction and the unleashing of the Saigyou Ayakashi's terror once again, she resigned herself to continuing her previous existence.

During Ten Desires, the heroine investigates in Hakugyokurou because they suspect that Yuyuko is not taking care of the spirits properly. But Yuyuko guides the heroine to the Graveyard behind the Myouren Temple.

  • (Touhou 7.5 and 10.5, alternate outfit) Kimono is white with dark blue trim instead of light blue with pink trim. Her hair is blonde as well.
  • (Touhou 13) Same as above, except she has a lighter shade of pink hair and her eyes are dark blue. Her kimono has has a ghost pattern. The kimono has a black trim instead of a dark blue one.



  • The characters for Saigyouji literally mean "West journey temple", and Yuyuko something like "Secluded child" or "Ghostly child." 'yuyu' (or 'yuuyuu', as in Yuu Yuu Hakusho) is reportedly the sound a Japanese ghost makes.
  • She has more Spell Cards in Ten Desires than is usual for a Stage 1 Boss in the Touhou series; in fact, she has more Spell Cards than the game's Stage 2 and 3 Bosses.
  • She is the only Stage 1 Boss, as well as Nazrin who has a purpose in the plot in Ten Desires. However she does not exactly have a role in the plot like Nazrin but rather being blamed for the incident but does know the incident herself.
  • Being re-introduced in Ten Desires, she strangely did not receive a remake on her sprite which stands out the most among the other Ten Desire cast's sprites.
  • One of Yuyuko's Scarlet Weather Rhapsody palettes resembles Ichirin Kumoi. As well, in Touhou Hisoutensoku, the sixth palette resembles Hong Meiling.
  • Yuyuko, along with Toyosatomimi no Miko, is the only final boss whose final spell is not immune to spells.
  • The name Saigyouji comes from a famous Japanese poet, 西行 法師 (Saigyō Hōshi), who lived in the late Heian period and the early Kamakura period. He passed away in a temple, which is why the character "寺"(tera) is added (in this case it is read "ji" although this character is usually read as (tera).
  • According to ZUN, Yuyuko looks like pure, innocent girl who knows nothing, but in fact she knows everything and pulling the strings from behind(Usually using Youmu). In other hands, Yakumo Yukari pretends to be a perfect mastermind who control everything, but she is not invincible, nor omniscient.
  • She is one of the few characters who revive (along with Eirin, Kaguya, Tenshi and Suwako) after being defeated the first time.
