The Perennial Wisdom’s Owner is Hugh and Dalian’s acquaintance. Also known as old man, he’s the owner of a second-hand bookshop who provides consultation on books to the couple.


The old man’s second-hand bookshop is located next to the capital, in the oldest academic town of the country. It’s found on a side street lined with restaurants and retail outlets. It’s a two-story building with tall bookshelves filled to capacity with books orderly arranged. Books which don’t fit the bookshelves are piled up on the floor. The silent place has not only scientific books, but also drama and popular novels. It’s not easy to find since its front, including its sign, is covered in soot. Its interior smells of dust, ink and paper. The entrance is accessed by climbing a creaky and narrow wooden staircase. Dalian gets in a good mood when she visits the bookstore.[1][2][3] In the anime, the place is known as The Perennial Wisdom.[4]

The old man stays behind a wooden counter at the back of the store. He knows Dalian for a long time. He knows that she’s a Biblioprincess and that she does not age. The owner has extensive knowledge about books, including Phantom Books, so Hugh and Dalian have the habit of consulting with him.[5] The old man has even information about figures from the underworld.[6] He sends letters to Hugh and Dalian when he obtains Phantom Books.[5] He also visits the Disward estate when he wants to borrow a book from Dalian.[7] He’s probably an acquaintance of the Disward family, since he has memories of Hugh as a child.[5]


The old man likes to playfully tease Dalian and Hugh. He sells strange books at a high price. He respects Dalian and he enjoys watching her examine Phantom Books. The old man has a calm, carefree personality. Dalian notices that, after many years, he never lost his liveliness. The old man addresses Hugh in a casual manner, which makes the latter uncomfortable.[5]


He’s a short gray-haired old man with round glasses, deep lines in his face and wrinkled fingers. He has clear, piercing eyes.[5] In the anime, he uses a black bow tie, and he's as tall as Hugh. He wears formal brown clothing over a white shirt.[4]


Book of Wisdom[]

Dalian wakes up Hugh before dawn. She plans to buy some books at the capital. They visit a bookstore located in an academic town. Dalian gets in a good mood. She wants to buy entire bookshelves, but Hugh tells her to choose only five or six books. They meet Kamilla, Hugh’s childhood friend, who was looking for a textbook for her students.[1] In the anime, the old man is shown writing on his desk.[4]

Book of Equivalence[]

The old man obtained a Phantom Book. He sends a letter to Hugh and Dalian. The old man wants Dalian to examine it. Hugh and Dalian reach the bookstore in the afternoon. The old man tells Hugh that he’s late. The old man bows politely to Dalian. In his eyes, she never seems to change. Dalian notices that he’s as lively as ever. As always, he has strange books for sale at a high price. Dalian offers Hugh’s organs in exchange for the books. The old man was surprised to learn that Hugh became Dalian’s key-keeper. The old man remembers when a three-years-old Hugh got himself lost in Wesley’s library and cried all night.

With no patience, Dalian tells the old man to show her the book. He rummages around his desk, moving books and stacks of paper, raising dust. After some time, he laughs awkwardly. He realizes that he sold the book by accident. In the morning, a client bought an entire bookshelf with items at a discount. The old man mistakenly included the book. Dalian slams his table, furious. The old man tells them about the client. It was a charming young lady who gave him a ride. The old man and the client talked on the way. The old man doesn’t know her name, but he describes her unusual clothes. Hugh and Dalian realize that the old man is referring to Kamilla. The couple worries that Kamilla will hurt herself while using the Book of Equivalence. Hugh and Dalian run out of the bookstore.[5]

Book of Soul Exchange[]

Dalian wants to read the sequel of Lenny Lents’ works. Hugh and Dalian visit his house. There, they meet Paula. The latter affirms to be Lents’ wife, but the couple suspects her. Hugh goes to a telegraph station. He sends a telegram to the old man, asking information about Paula. Later, the old man answers Hugh by telegram. Hugh learns that Paula Dickinson is a crazy fan who torments Lents’ life. Lents dies after the events of Book of Soul Exchange, so Dalian decides to write the sequel herself with the help of Hugh. She even asked the old man to gather some fanmade stories involving Lents’ characters to use as reference.[8]

The cover depicts a young girl holding a violin. The old man teases Hugh by saying that the woman is indeed very attractive. The old man reveals that she’s Christabel Sistine, a famous violinist who plays the impossible sonatas of Guglielmo Baldini. The old man heard that people pay a fortune to listen to her. He removes a newspaper from the pile of papers on his desk. The article reveals that Christabel is building her own concert hall. The old man heard that Christabel is being supported by a cunning entrepreneur. The old man starts to organize the books around.[3]

Heath, now resurrected before the events which triggered the disaster, has the opportunity to destroy the book. When Hugh returns, he learns that the book became a heap of scraps. He ensures Dalian that he will apologize to the old man.[7]

The Template Book[]

Hugh and Dalian meet Leon Kim Keynes. The latter is being threatened by an immortal man. The next morning, Hugh and Dalian visit the second-hand bookshop. The old man usually doesn’t see them so early. Dalian is looking for a killer, but the old man explains that he only sells books. Hugh asks for information about a book carried by the assassin Wesley Clade. Hugh talks about Clade, but the old man apparently already knows about him. The old man somehow learned that the assassin is threatening the Keynes family. The old man explains that Clade shared a dormitory with author Zenova Hallward. The author’s description of Clade became a Phantom Book. Clade will have eternal life and young appearance as long as the Template Book exists. The old man rummages through a pile of books. He gives a book to Hugh. The book is a copy of the Template Book. Clade printed and distributed copies of the Phantom Book throughout the world in order to preserve the forbidden knowledge.[6]
