Yukari Yakumo

The youkai of boundaries, who awakens at spring.
Her main ability allows her to manipulate boundaries of all sorts.

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.

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.

Ran Yakumo

Extra Boss, and Yukari's shikigami. She does Yukari's work for her while her master sleeps. Her main ability is control of shikigami.

Every year, when cherry blossoms are about to bloom, she visits the Netherworld for flower viewing. The cherry blossoms seemed to be lasting somewhat longer than usual this year. Just as she was considering that, some living humans dropped in. She watched them with interest for a few moments.

She later heard that her shikigami had been defeated by them, so she plotted a little revenge.

In truth, she is a fox turned youkai. Like Chen, her shape is unchanged and she has a well-rounded personality. Even without looking closely, it's obvious that she has several tails. As a matter of fact, when it matters, she has plenty of power even without support from a shikigami.

Chen

Stage 2 Boss, a shikigami that possesses a cat living in the mountain. Her primary ability is black magic.

She is Ran's shikigami, which makes her a shikigami of a shikigami of a youkai. Although she's a shikigami, her normal form is not a charm or anything like that; she always remains in her human-like form. Even without being in shikigami possession she can speak the human language and fly around, but her abilities will be limited to merely surprising people. Also, while non-possessed, neither her appearance nor personality changes, but she still sits by a kotatsu in the winter.
