Patchouli Knowledge is a friend of Remilia and can often be found in the Scarlet Devil Mansion's great library. Unashamed by the nickname "Unmoving Great Library," she possesses great knowledge on a vast number of topics.

Sakuya Izayoi is the Scarlet Devil Mansion's head maid. With her ability to manipulate time, she supports both the public and private affairs of the mansion.

Jack-o-Lanterns are a common symbol of Halloween, but they were originally carved from turnips and were used to ward off evil. At the time when the Halloween tradition began to take root in America, many pumpkins were harvested each year. This is said to be why pumpkins came to replace turnips... Actually, let's give the history lesson a rest. In modern times, most regions that celebrate Halloween do so by enjoying the spooky atmosphere it brings. As such, knowledge of its history isn't nearly as important as getting into the festival spirit.

Scrambled Youkai Network Patchouli was busy preparing for the party when Sakuya appeared with a specially made pumpkin pie and a sand timer in hand and suggested she take a break. According to Sakuya, Remilia had given Patchouli permission to rest for thirty minutes. "Remilia really is getting carried away, asking Patchouli to time her break with a sand timer like this," thought Sakuya as she let out a sigh.

Patchouli munched away happily on the pie while drinking a cup of her favorite tea, which Sakuya had brewed for her. She was enjoying her pie so much that she failed to notice the sand timer atop the table was about to run out, signaling the end of her break. Then, without saying a word, Sakuya stopped time and flipped the timer, for she wished to preserve Patchouli's happiness a little while longer.
