It connects the readers’ minds.


Emilie Gisela;
Mother Eva Gisela



For the light novel chapter, see Chapter 4 (light novel 5).

Book of Connection or Liber Iunctio (リべル・ユンクティオ Riberu Yunkutio) is a Phantom Book Egg read by the sisters Emilie and Eva. It caused the connection of the minds of all inhabitants of Nudelwald. The Phantom Book Egg is present in the Book of Connection story.

The original Phantom Book Egg is an old Bible with velvet cover, its corners protected by brass. The copies are manuscripts, ancient Bible translations, bounded with a red cover with the title "Liber Iunctio" written in silver.[1]


"Liber Iunctio" is Latin for "Book of Joining, Junction or Union".[2]

Six months before the main events of Book of Connection, Rasiel and the Professor gave the original Phantom Book Egg to Emilie and Eva. The sisters read the unstable Phantom Book Egg, resulting in Eva’s death, her soul absorbed by Emilie. The latter assumed her sister’s position as abbess of Nudelwald. Emilie replaced the nuns and monks’ Bibles with copies of the Book of Connection, uniting everyone’s minds. The ordinary townsfolk were also brainwashed after reading the copies.

Rasiel and the Professor want to make the Phantom Book Egg turn into a complete Phantom Book. The Professor also wishes to use the connected minds to mine radioactive ores and to develop a fission bomb, all to strengthen the power of his homeland. Emilie plans to connect the minds of all humans and free them from suffering.[1]


The Phantom Book Egg and its copies connect readers, merging their souls. Their identities are erased, they become one, able to move as synchronized machines. What one sees, thinks or feels is known by everyone else. Thousands of brains working together, simultaneously, can perform huge and complex calculations which are impossible to an individual, revealing an incredible computing capacity. The brains act like chips in a circuit. The connected minds can quickly define the best course of action.

For instance, monks united by the Book of Connection are able to easily determine the resonance frequency of a structure in order to make a building collapse with just a touch. As information is transmitted through the nervous system by weak electric signals, a large quantity of minds connected in series will amplify such signals and cause a visible discharge. Thus, users can strike targets with lightning. The copies of the Book of Connection work as access points for a network. The copies are powerless individually, but together form a dangerous communication device.

A negative side in relation to such power is that, if someone in the network feels pain or is affected by a Phantom Book, everyone else will suffer the consequences. The original reader seems to have a better resistance to attacks at the network. The Book of Connection is an unstable Phantom Book Egg which can kill its user. When its power is disrupted, all personalities and memories from the network flow into the mind of the original reader, overwhelming him. In this case, killing the original reader is required to save everyone else in the network. As alternative, the Book of Oblivion may be used to erase everyone's memories.[1]


Hugh and Dalian read an article about a distressed miner who ran away from Nudelwald. The miner was carrying some kind of manuscript. Monks chased after him, also holding the same strange book with red cover. The monks performed a miracle and killed the miner by praying, without touching the man. Hugh and Dalian decide to explore Nudelwald, suspecting that they will find a Phantom Book.

The Professor thanks the abbess for providing the monks. The men are working on mysterious formulas as a single network of calculating machines. The abbess, in turn, shows her gratitude for the book she received from Rasiel and the Professor. The abbess holds a Bible with velvet cover. According to her, the believers have forgot about their loneliness and anxieties. They’ve gained true understanding and peace. Rasiel reminds her that the book is still unstable.

Hugh and Dalian are welcome by four nuns, one of them holding a manuscript with red cover. Hugh asks about the book to another nun who was setting the table. According to the nun, the book, called “Liber Iunctio”, is an ancient translation of the Bible transmitted in the monastery from generation to generation. Writing copies of the Bible is part of the training of nuns. The nun offers a copy to Hugh, but he declines.

While exploring the small town, Hugh and Dalian notice that every townsfolk has a book with red cover in hands. Dalian doesn’t notice magic or anything which indicates the presence of a Phantom Book. They meet once again the nun who threw snowballs at them earlier. The nun carries a basket. She explains that, after working as miners for the monastery, the people of Nudelwald became sick and were discarded. However, no one dares to oppose the monastery. After all, the monks perform miracles to intimidate and kill their enemies. Later, Hugh learns from the Professor that such miracles may be connected to a Phantom Book Egg.

Seven young monks enter the church maintained by the nun. They also have Bibles with red cover. They tell her to return the book. They know Hugh and Dalian. One of the monks opens his book. He’s enveloped by electric discharge. He extends his arm, his eyes turn white for a moment. He sends a lightning to one of the nun’s patients, killing the man instantly. Hugh reaches for his pocket, but a monk interrupts him, saying that he knows about the weapon. The monks describe the type of Hugh’s revolver and the number of bullets. Hugh gives up. The monks, with their supernatural abilities, know that Hugh won't shoot them. If even he shot them, they will only evade the bullets.

The nun removes a book with velvet cover from her basket and gives it to the monks. One of the monks touch a pillar inside the church, making the building collapse. Hugh, Dalian and Queneau, one of the nun’s patients, are the only survivors. According to Queneau, the monastery uses the Book of Connection to merge people’s minds, explaining the miracles performed by the monks. Those holding a red book are connected to a network, sharing feelings and thoughts with everyone.

Inside the largest church of Nudelwald, the abbess prepares to open the book with velvet cover, the original Book of Connection. The abbess had reunited the monks and residents of Nudelwald for a ceremony. She controls the copies of the Book of Connection and its owners, like a hive queen controls her colony. She wants to unite the whole world. Rasiel and the Professor want to see the Phantom Book Egg turn into a complete Phantom Book. Hugh and Dalian interrupt the ceremony. It’s revealed that the abbess and the nun are sisters who exchanged identities. They had read the Book of Connection but, since it’s an unstable Phantom Book Egg, Eva died and Emilie absorbed her soul and replaced her as abbess of Nudelwald. Emilie, disguised as Eva, plans to merge her own soul with her sister’s. Eva will never oppose Emilie again.

Emilie-Eva tells her followers to attack Hugh and Dalian. The latter recites an adaptation of a biblical verse, forcing the people around to think only about fried breads. Hugh and Dalian had prepared for trouble, reading the Book of Imprint to one of the brainwashed individuals. The brothers and sisters enter a state of trance. Dalian’s words work as a virus infecting a network. Emilie-Eva, as the original reader, is the only one unaffected. However, she screams in pain. Rasiel steps on the Book of Connection, frustrated with Hugh and Dalian's intervention.

Now that the Book of Connection is no longer active, all personalities and memories flow into the mind of Emilie-Eva, the original reader. Electric discharges run around the abbess, making her suffer from muscle contractions and burned flesh. Emilie-Eva’s feelings are transmitted to her followers, who also scream in pain. According to Dalian, Emilie-Eva must die for the others to survive. The abbess, using Eva’s voice, asks the couple to kill her. Hugh solves the problem by using the Book of Oblivion to erase the victims’ memories of the past six months. After that, the sisters Emilie and Eva lived as one, without knowing they were originally two individuals.[1]


  • The connection of at least three brains was already reported. Further studies may allow subjects to connect their minds into a network, even across the web, and share thoughts, maybe even pool mental resources in order to solve a problem.[3]
    • A wetware computer is an organic computer composed of organic material such as living neurons or more complex structures like brains. It's still largely conceptual.[4] Harnessing the power and efficiency of the human brain may be the future of computing.[5]
    • In science fiction, a hive mind is a plot device in which multiple minds, or consciousnesses, are linked into a single, collective consciousness or intelligence. It's formed by any fictional plot device that facilitates brain to brain communication. The linked individuals have no identity or free will and are possessed or mind-controlled as extensions of the hive mind.[6]
    • The concept of group mind in fiction is mentioned as early as 1930, in the Last and First Men, by British author Olaf Stapledon. In this work, the most advanced humans are able to connect their minds. Eventually a single group mind unites the entire species.[7]
    • In the anime series Psycho-Pass, humans brains are maintained inside chambers to form the processing power of a large computer.[8]
