|Mastermind Behind the Spiriting Away|
The youkai of boundaries, who awakens at spring.
Her main ability allows her to manipulate boundaries of all sorts.
She and Yuyuko have known each other for a long time, but Yukari is not a ghost. She lives in the remotest place in Gensokyo. Her lifestyle involves a lot of staring at the Hakurei Border.
When humans from the outer world wander into Gensokyo, it's all thanks to fluctuations in the boundary caused by Yukari. There is an enchanting element about the phenomenon which people like to call "Spirited Away"; if it is ever discovered that spiriting away is not the work of gods, but the meddling of a youkai girl, the term will lose all of its mystique.
Yukari usually doesn't act on her own, preferring instead to have Ran handle the details of daily life. But, since she is almost always asleep, she has no idea what Ran does while she sleeps.
When she heard that Ran had been defeated by someone, she became mildly surprised before going back to sleep.
After waking up from her nap, she finally noticed that spring had graced her place of residence. The truth is that spring had been around for the past 10 days, but she forgot it whenever she went to bed and woke up just as surprised the next time.
She couldn't sleep carelessly until Ran fully recovered, but she opted to sleep on the problem.
The next time she woke up, she received a request from Yuyuko asking her to restore the boundary between the world of the living and the world of the dead. It was a ridiculous request since Yuyuko was the one who weakened it to begin with, so Yukari rubbed the sleep from her eyes and set out for repairs.
It had been quite a while since Yukari's last visit to the Netherworld, and she was curious to see that it was bustling with excitement. She thought the Saigyouji family were more quiet, laid-back folk, but she shrugged and decided Yuyuko had just had a change in taste.
She met the gardener, Youmu, along the way and heard about the situation. Youmu admitted that they seemed to be in quite a mess, but it sounded like well-earned punishment to Yukari.
Everyone always seemed to be bent out of shape about that youkai cherry tree, and nothing else. Surely, it had drained the spirit from too many human lives. Yukari knew it was dangerous. However, she realized there was nothing she could do about it.
Yukari had known Yuyuko since before her death. She also knew that it was not Yuyuko who was sealed by the Saigyou Ayakashi...
- ... but that it was Yuyuko's body that was sealing the Saigyou Ayakashi.
