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's Voile library, and a close friend to Remilia Scarlet. 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 uttered by Billy Herrington. Such images are tagged with: "Patchouli, Urgh!" in Pixiv.
She has long purple hair with blunt bangs, matching eyes, and multiple blue and red/pink hair bows. She wears a pink or white mob cap with a crescent ornament on it, as well as a ribbon, and single or double bun covers. She also wears a vertically striped, purple dress under a pink robe with long, wide sleeves, and has white shoes or purple boots with bows on them.
