Dalian is the Black Biblioprincess or the Black Reading Princess. She's the custodian of the Bibliotheca Mystica de Dantalian housing 900,666 Phantom Books. Her key-keeper is Hugh. She's one of the main protagonists of The Mystic Archives of Dantalian.


The name "Dalian" derives from "Dantalian". What little is known of Dalian is that she interacted with Hugh in his childhood, giving him the key for the gates to the Labyrinth Library, and that her previous key-keeper was his grandfather Wesley. Hugh also promised to be her friend and to take her to the outside world. In the manga, she was also present when Wesley took The Harlequinade from his grandson' hands.

Additionally, many characters seem to know Dalian or know of her, which implies that she is much older than she appears, possibly centuries old. Sometimes she calls other people "human", which can imply that she is a different being.

She's been waiting the next key-keeper since Wesley's death. Because she was bored, she read all the books from his collection.


Dalian appears in both light novel/manga and anime adaptation as a young girl with long, black hair reaching her waist, and pale skin. She appears to be between 12 to 13 years old. She has an unusual appearance; with the contrast between her hair and skin, and her style of dress, she is sometimes mistaken for a doll. As described in the light novel, Dalian wears an odd combination of dress and armor, which includes armored boots and tassets. It usually surprises people who never seen her. Both versions sport a metallic ring around the neck and are often carrying or reading a book.


In the anime adaptation, Dalian wears a black, Victorian-style dress with red laces and white frills in its sleeves and hem. She has a small tiara and an ornate pendant, which serves as the lock to the Bibliotheca. When outside, she uses a black bonnet, which has a red rose attached to its front part. When it's cold, she is seen with a black and white overcoat, brown gloves and a white fur hat, with a red rose in its right side. Unlike in the light novel, Dalian's eyes are a dark shade of pink, rather than red. Part of her hair rises when she sees sweets.

Light novel and manga Edit

In the light novel and manga version of The Mystic Archives of Dantalian, Dalian typically wears a white mob cap, in addition to a black and red tea gown with white lining. She wears a padlock chained to her neck, acting as the gates of the Bibliotheca. The ring around her neck has a darker hue and looks sturdier compared with what is seen in the anime. When she's outside, she uses a parasol. Her eyes are a shade of red in the illustrations. However, the light novel describes her eyes as deep black.

Dalian tends to be flippant and rude to everybody, in particular Hugh, whom is usually hit by her. However, despite this, she becomes jealous or possessive whenever he interacts with another woman, for instance Camilla. She has already shown concern for Hugh in difficult situations and even tried to attract his attention by changing her hairstyle. Otherwise, she will be in a bad mood and argue when her wishes are not met. Dalian tries to hide her emotions with a grumpy attitude, though her eyes and blush usually reveal what she's thinking. She hardly loses her calm in a hostile environment. Dalian is shown to respect Wesley Disward and grive for his death.

She is a sweet tooth, placing great importance on buns, scones, and tea. This is often used by Camilla to bribe Dalian. Dalian has great will to solve cases in order to seal the Phantom Books, but otherwise she shows no interest, except for books and tea time. She is able to read books from various areas and languages.

Plot Edit

Turn-Up Book Edit

Dalian is reading in the basement of Wesley's mansion until she's found by Hugh. He mistakes her for a doll at first. He introduces himself. At first, she's suspicious of Hugh. Dalian hits him when she hears her name was mistakenly thought to refer to a pet. They have a conversation in the kitchen, where she eats the bread offered by Hugh, complaining about the lack of sugar. When Hugh tries to find a clue related to The Mystic Archives of Dantalian, Dalian affirms he would not find anything. She learns about Hugh and how he's disappointed by his grandfather's collection. Before he can talk about his golden key, they are interrupted. Someone appears to take Hugh to Lord Henry Conrad's mansion.

Opening the gate

Dalian gives Hugh the right to open the Library's gate for the first time.

Dalian says Hugh would find the evidence proving Conrad killed his grandfather to obtain a valuable book. Inside the mansion, they discover bodies and destruction. They are attacked by a clown, which is shot by Hugh. Soon after, Hugh has a confrontation against a tiger.[1] In the anime adaptation, Hugh confronts a lion instead.[2] They go into hiding. Dalian explains the situation was caused by The Harlequinade, a Phantom Book. She also describes the purpose of The Mystic Archives of Dantalian. When they are stopped by a dragon, Hugh tells Dalian to run away while he stays behind.[1] In the manga, they are opposed by a tiger and other creatures from The Harlequinade.[3] Instead of running away, Dalian reveals to be custodian of The Mystic Archives of Dantalian and gives him the right to open it. Hugh uses his golden key and they obtain a grimorium called "Liber de Nymphis" from inside the Library. She reads it to defeat the creature.[1] Alternatively, in the anime, Hugh uses the Phantom Book to make the dragon disappear.[2] Dalian seals The Harlequinade after finding Conrad's body. They leave the mansion together. Dalian is exposed as "the world in the vase". Thereafter, Hugh starts to take care of Dalian.[1]
