See Character Titles

Patchouli Knowledge is a very smart, anemic magician from the Scarlet Devil Mansion. Although she has only been a boss in one game, and playable character in three others, she is still a very popular character, showing up in many endings and is referenced quite often. She spends most of her time in the mansion's library reading and writing magic books. It seems that she's capable of very powerful magic of all kinds, using many elements in a single spell, but due to anemia and general poor health she's often unable to recite her spells.

In Embodiment of Scarlet Devil, she attempts to stop the player from going further into the Scarlet Devil Mansion. In the extra stage, she tries again, and uses much more powerful magic, in part because she says she "felt better that day".

She rarely leaves the Scarlet Devil Mansion, but in Immaterial and Missing Power makes an exception to go investigate the recent strange events. In other character's scenarios she's visited by several of them thinking that she, of all people, must know what the strange mist is. However, getting a straight answer from her is anything but easy. In Scarlet Weather Rhapsody, she decided to find what was the cause of the weather disaster. In the events of Subterranean Animism, she noticed the abnormalities in the underground, and had Marisa go with the help of Yukari preparing Marisa's options.

Fun Facts

  • Her first name, "Patchouli," could be taken from name of a herb used in perfumes and incense. Her last name, "Knowledge," appears to be a reference to her amount of knowledge, though few other characters seem to have such literal surnames.
  • After being defeated in Marisa's scenario in IaMP, she utters "mukyu~". Since then, fan works have often depicted her using this sound as a sign of surprise or pouting.
  • In some fan comics, Patchouli is portrayed as an otaku, and sometimes as a fan of the villain Frieza from the manga DragonBall Z.
  • In other fan comics, Patchouli is considered a hikikomori due to her apparent habit of spending all her time in one room (the library) and rarely ever stepping outside. She would only have to keep this up for 6 months to meet the time span given in the definition, and she's been living like that for the past 100 years.
  • Patchouli has been rumored to be the inspiration for the character Yue Ayase from the manga Negima! Magister Negi Magi. Like Patchouli, Yue is a short, quiet girl with long purple hair, an unexcitable personality, an affinity for books (she is a librarian) and magic (she is also known to dress in a witch outfit similar to Marisa's).
  • The crescent on Patchouli's hat could be the crescent in the Sanskrit "Hum", part of the Mantra "Om mani padme hum". In Buddhism, it stands for knowledge and purity and is associated with the color white—all the 7 colors combined.
  • There is an ongoing debate (mostly in 2channel) over whether she is large-breasted or small-breasted, as her baggy clothing makes it impossible to distinguish the size of her breasts. The former claim is based on how she never leaves her room and thus must gain weight since she never gets any exercise, while the latter claim is based on her physical weakness and generally childlike appearance.
  • She has waterproof books that Marisa finds interest in reading in the bath.
  • As of Hisoutensoku Patchouli has had appearances in 9 of the 11 windows games when counting Hisoutensoku as a standalone. This makes her the most featured character second only to the two main characters.
  • Apparently, Patchouli is not only an elemental mage, but also dabbles in demonology, as evidenced by her assistant Koakuma. its possible that Koakuma is a summon made by Patchouli to help her out in the library.
  • Patchouli's magic based on elements of Wood, Fire, Metal, Water and Earth. In Chinese signs of the Zodiac there are five beasts: Azure Dragon, Red Bird, White Tiger, Black Turtle and Yellow Dragon. Each of the five beasts refer to same elements Patchouli use: Azure Dragon - Wood, Red Bird - Fire, White Tiger - Metal, Black Turtle - Water and Yellow Dragon - Earth.

Patchouli Knowledge






The Girl of Knowledge and Shadow
Patchouli Knowledge

Ability: the power to control fire, water, wood, earth, metal, sun, and moon

The 4th stage boss. She is the friend of the young mistress and is a witch who has lived for 100 years. The "One-week Girl".

Her weak constitution makes her poor at physical combat, but she makes up for for that with her sheer variety of magical attacks. Patchouli's ribbon is not a holy charm, but rather an accessory that boosts magic power.

Since she's a genuine witch, her magical power is terrifying. However, because of the asthma she was born with, she often cannot recite the spells. She also seems to have a vitamin A deficiency.

Maybe her windowless library room is dusty. No, obviously, it's very dusty. But, since she spends all her time near books she considers them a part of herself, and cannot stand to be separated from them. This is how she has spent about a hundred years.

The Unmoving Great Library, Patchouli Knowledge
Species: Witch
Residence: Scarlet Devil Mansion
Ability: The ability to use magic (mainly elemental magic)

A witch who has settled down in the Scarlet Devil Mansion. Unlike the mistress of the house, she is not weak against sunlight; however, she does not go out much. She spends her days in a library where the sunlight cannot reach. This is so that the books won't be damaged, but the unhealthy atmosphere is bad for her health.

She doesn't have a very proactive personality, but rather always walks her own path. However, she is always interested where knowledge is concerned and will proactively go and try to acquire it. She does everything by the book, but still makes a lot of mistakes.

Although she is quite skillful, her complete lack of physical fighting ability can't be helped. She pretty much never attempts to directly punch or kick her opponent. She makes up for this with her knowledge of a great variety of powerful magic. She's more at ease using magic than trying to attack physically. Dividing the magic she uses according to the days of the week is a secret hobby of hers, but no one has realized this.

  Patchouli Knowledge





The Great Unmoving Library
Patchouli Knowledge

Species: magician
Ability: power to use magic

A magician that lives in the Scarlet Devil Manor.

She noticed the great number of earth spirits that came from the geyser. On further investigation, they turned out not to be earth spirits, but evil spirits that looked just like phantoms. These evil spirits were spirits that bore a grudge against the world. They were a threat to humans, youkai, and fairies alike.

She wanted to find out what was causing the evil spirits to appear, but going herself would have been quite dangerous. Troubled, Patchouli went to see Yukari. Yukari, who was also surprised by the incident, came up with a plan to make the humans go explore the underground.

Book Synopsis

Bohemian Archive in Japanese Red

Main article: Article and Interview: Patchouli

A Setsubun (Hot-Bean-Throwing) Festival has been staged at the Scarlet Devil Mansion, revealed to have been set up by Patchouli. Upon being questioned regarding this strange festival, amidst the chaos of the Mansion's staff, Patchouli seems to think it ridiculous that Aya would call it "out-of-season"; Patchouli regards the festival as a means of Strengthening the Mansion against the Oni. When asked why, she simply responds that it never hurts to be prepared.

At an unspecified later date, Aya interviews Patchouli in her library, and the two have a relatively pointless conversation regarding the festival until Aya asks if any Oni have been spotted. Patchouli then discusses the Oni with Aya, addressing their weaknesses, and explains the significance of Setsubun in relation to the Oni.

She ends the interview on a note of her own weakness, stating that she hates the sun as it damages her books and messes up her hair.
