The "Unmoving Great Library". Stage 4 boss of [[Touhou]]'s [[Embodiment of Scarlet Devil]] and later a recurring playable character in the first few fighting games.

A magician youkai, resident librarian and instructor of the [[Scarlet Devil Mansion]]. She has mastery over the seven elements corresponding to Japanese weekday names - Sun, Moon, Fire, Metal, Wood, Water and Earth - earning her the nickname "One-Week Wizard", but her reclusive lifestyle (she's apparently not left her library in 100 years, which is interpreted in some doujins as signs of [[hikikomori]] behavior) has taken a toll on her health, limiting her powers by way of asthma and anemia. Due to her baggy clothing, her bust size and overall body shape are still open to debate.

On [[NicoNico]], she is linked to [[Gachimuchi]] thanks to "a certain misheard line":https://www.nicovideo.jp/watch/sm2852390 uttered by [[Billy Herrington]]. Such images are tagged with: "Patchouli, Urgh!" in Pixiv.
