Hugh Anthony Disward


Inside the Labyrinth Library

The real title of this Phantom Book was never revealed in the series. It was used by Hugh to leave a collapsed room about to be set on fire by Roy Hurston. It's present in the Pedigree story.


It’s a grimoire left by a magician who worshipped the Outer God (外なる神 Sotonarukami), a deity who lives in the cracks between dimensions.[1]

The Phantom Book is sealed inside the Labyrinth Library under the number 29,576.[2] According to Hugh, Phantom Books with such a power are not rare.[1]


Its user can open a gate to another world and use it to transfer himself and others from one point to another without moving in the space between them.

In the series, three characters were able to leave a sealed room to reach a safe spot nearby thanks to its powers.[1]

When the Phantom Book is used in the manga, a huge winged object resembling a caduceus comes out from the clouds in the sky, pointing to the ground.[2]

The winged object born from the unnamed Phantom Book


Roy Hurston is about to kill Hugh, Dalian and the Beast of Ashwell. The mad man had just learned that his grandfather Boyd considered him a failure, naming Chez as the new head of the family and inheritor of The Pedigree of All Creations. After shooting Boyd dead, Roy was ready to set his secret laboratory on fire and kill the others. Hugh couldn’t find a spot to escape. After all, an explosion made the underground room partially collapse. Chez, in the form of a beast, was trying to support the ceiling. Roy watches them from above while pouring gasoline. Dalian gives Hugh the right to open the gate. Roy throws a lighter at the same time that Hugh opens the Labyrinth Library.

Roy laughs hysterically while looking down the burnt remains of Boyd’s workroom. He stops when Hugh, Dalian and the Beast of Ashwell appear behind him. Hugh closes the book he’s holding, explaining they had just used a Phantom Book to open a gate to another world.[1]


  • The term "Outer Gods" is present in the Cthulhu Mythos, a fictional universe in the works of American author H. P. Lovecraft and other contributors, usually said to have originated from Lovecraft’s short story The Call of Cthulhu, written in 1926. Some of these deities dwell in other dimensions.[3][4]
