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 Voilelibrary, 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.
