Yami to Bōshi to Hon no Tabibito (ヤミと帽子と本の旅人?, possibly translated as Darkness, the Hat, and the Travelers of the Books), also known as Yamibō/Yamibou for short, is both a Japanese adult visual novel published in late 2002 by Root, and a non-adult, thirteen episode anime series released by Root and Studio Deen in 2003.[1] Although the characters and their relationships remain basically the same in the game and anime, the storyline is quite different.



The game begins with a girl who is taken to a strange, magical realm by a dragon. She apparently was taken to the library where all past, present, and future realities are kept within the books. The player is a young man who has come from one of these books as well, but has forgotten his way back home. The player is commissioned to find the missing girl by the denizens of the library, and starts his search by entering different books.


The story follows the travels of Hazuki Azuma, a tall, brooding high-school girl, as she searches for her adopted older sister and love interest, Hatsumi, in many different "book worlds". After the disappearance of her sister, a talking parakeet nicknamed Ken-chan introduces Hazuki to Lilith, the caretaker of the Great Library. Each book in the library contains a different world, and the guardian of the library takes on the title Yami.


Hazuki Azuma (東 葉月 Azuma Hazuki?)
Voiced by: Yuki Iwata (game), Mamiko Noto (anime)
Hazuki is quiet and serious, with long dark blue hair and sharp blue eyes. She uses the relatively masculine pronoun "boku" for referring to herself "I". Hazuki appears cold and unfriendly and is fiercely protective of Hatsumi. She is actually very vulnerable and romantic, even to the point of being submissive, but refuses to show weakness or depend on anyone but her adoptive sister, Hatsumi — unless she is forced to. One example of this is her first encounter with Lilith, where she initially refuses Lilith's help in looking for Hatsumi/Eve. Only when Lilith notes she won't be able to travel from world to world without her, does Hazuki agree to travel with her and even then, only tacitly. As soon as she no longer has any need for Lilith's help, she shows no regard for her or her wishes with regards to Eve. Hazuki idolizes Hatsumi extremely and, as such, considers her sexual attraction to Hatsumi vulgar and shameful.
Hatsumi Azuma (東 初美 Azuma Hatsumi?)
Voiced by: Anna Akashi (game), Ai Shimizu (anime)
Hatsumi is Hazuki's adopted older sister and love interest. Hatsumi appears to be mute (though it is proven otherwise on several occasions) and communicates mostly through gestures and facial expressions. Despite being older, Hatsumi is much shorter and thinner than Hazuki. Although it seems that Hazuki's love is one-sided, episode seven shows that Hatsumi does have feelings for Hazuki and was trying to express herself as best as she could with the knowledge that she cannot stay beyond her sixteenth birthday (suggestions of this were shown along the way by her sending Hazuki anonymous love letters — later expressed in full and in words toward the end of the anime). In the first episode, Hatsumi disappears in a burst of green light ("sōma") at midnight on her sixteenth birthday, as Hazuki tries to steal a kiss in her sleep. The events that follow lead Hazuki to a mysterious library in another dimension, in which all the worlds are kept in books. Hazuki learns from the Library guardian, Lilith, that Hatsumi is only one of the forms of the previous guardian (Eve), and that Eve stays in different books for fun until she turns sixteen.
Lilith (リリス Ririsu?)
Voiced by: Misaki Asamiya (game), Sanae Kobayashi (anime)
Lilith is the guardian of the library. She is the third Yami, after Adam, the creator of all the worlds, and Eve. In the anime, Lilith is attracted to Hazuki and flirts relentlessly, though she is always turned down. Lilith appears to dislike Eve and have interest only in her own ends, but her kind and vulnerable sides are sometimes shown, especially when she encounters children in trouble; adults do not seem to move her to compassion as much. Her more childish mannerisms are fairly constant, but Lilith sometimes shows considerable wisdom and knowledge. She claims that Eve left the duty of being Yami and went off to play in the book worlds, and so she wants to find Eve and return her to the library.
Ken (ケン?)
Ken is a yellow cockatiel who can talk. In the anime, he accompanies Lilith in her travels, while in the game he accompanies the nameless main character. He speaks in very heavy kansai-ben. Ken is loud, obnoxious, lecherous and perverted, as well as overly confident and a bit too slow to stay out of trouble. He usually ends up punched, squashed, beaten or otherwise violated, either as a result of tasks given to him by Lilith, or because of his big mouth and perverted tendencies. In the game, his true form is a kendappa and he is working for Arya.
Arya (アーヤ Āya?)
Voiced by: Jun Fukuyama (anime)
Arya is a mysterious silver-haired boy who appears in every episode of the anime and during certain times in the game. In the anime he claims to be cleaning up after Hazuki and Lilith. Also, he offers to perform repairs on Tamamonomae's Space Hall. He is always cosplaying as some type of character or animal. At the end of the anime series, he is shown closing a book that seems to contain the world of the Book Keepers. He is the main narrator of the story, and his short exits and introductions are often the only transition between stories.
Kogechibi (コゲチビ?)
Voiced by: Ai Shimizu (anime)
Kogechibi lives in the library, and looks like a four-inch (102 mm) -tall Eve, though with different colored eyes. "Koge" refers to the one-eyed cloak that covers all of her but the eyes. In the game, when the main character is occupying "Koge", the girl is referred to as "O-chibi-chan" ("o" being an honorific and "chan" an endearment). Kogechibi's vocabulary is composed of unintellible sounds akin to baby talk. In the anime, she has a disturbing love of fireworks and can say a few words if they have something to do with explosives. She plays a small part in the plot, but is mostly comic relief in the anime. In the game, it is revealed that the guardians "fragment" when they overexert themselves, and that the fragments take on a life of their own. Kogechibi is a fragment of Eve.
Gargantua (ガルガンチュア Garuganchua?)
Voiced by: Shinichiro Miki (anime)
Gargantua appears in episode two of the anime as a madman, with three bumbling demonic henchmen and a servant named Seiren (derived from the Hellenic Siren). His main goal is to find Eve who is present as the mute, magic-using Jill, assistant caretaker of the orphanage. Gargantua is fiercely attached to her, and accidentally stabs her fatally with a knife when he jealously tries to dislodge a fellow orphan, Ritsuko, from Jill's arms. Jill's body disappears in an explosion of souma, drenching the two children in her life force. In the game, Gargantua and the main character both hold and try to acquire more fragments of Eve. For a while, Gargantua takes over Joe Harry and the command of the "hunters" (smaller, one-eyed hat-looking creatures). At the end of the anime, thanks to Eve and Tamamonomae, Gargantua has a change of heart and returns to the realm Lilith gave him for the sacrifice of princess Mariel, taking Ritsuko with him.
Ritsuko (リツコ?)
Voiced by: Tomomi Misaki (game), Kikuko Inoue (anime)
Ritsuko is an immortal magic user and appears no older than 25, despite being over a century old. Ritsuko travels the countryside performing healing miracles. She has never forgotten Jill or Gargantua, and carries small portraits of them in her locket. When she comes to the castle to heal Princess Mariel, she is taken in as the court alchemist. While escorting the princess around the village, Ritsuko meets Gargantua, who is also immortal because of Jill's souma and has learned dark magic. He kidnaps Princess Mariel and tries to sacrifice her to Lilith, in order to be shown where Eve is. Ritsuko stops him only too late and is framed for the kidnapping and thrown into a dungeon. Ritsuko is a user of sexual magic in the game, and one of the bodies occupied by the player is under her spell. She has a clone who was made by future herself, which is also seen travelling through the books with two children. At the end of the anime, thanks to some interference by Eve and Tamamonomae, Gargantua returns for Ritsuko, freeing her from her cell and taking her back with him to his own realm.
Milka (ミルカ Miruka?)
Voiced by: Miyu Matsuki (anime)
Milka appears in episode six under the care of Seiren. She is a girl with a cruel past who is trapped in her five-year-old body. Milka lives on an island, and has no one to befriend but Seiren and her white tiger, Rascaless. Her initial caretaker was an older woman who used to whip the child as a punishment for such trivial offences. Eventually, the old woman is killed by Rascaless when Milka isn't watching. Initially afraid of Hazuki and Lilith, she warms up to them and has Seiren take them to the villa at the center of the island. In the game, Milka is sent to live on the island by her older brother, for whom she has romantic feelings, because of her poor health. Seiren sings on the cliffs everyday to keep all of Milka's brother's soldiers under her spell, and Milka on the island. After Seiren and Lilith's reconciliation, Milka goes back to her brother with Rascaless.
Fujihime (藤姫 Princess Fuji or Princess of the Wisteria?)
Voiced by: Anna Akashi (game), Ai Shimizu (anime)
Fujihime appears in a book-world that corresponds to the samurai era of Japan. Fujihime looks like Hatsumi, but has purple eyes instead of red. Fujihime is not another form of Eve. She is Spirit of a japanese wieteria (called Fuji) who is gifted power from Eve. She can talk, and possesses the comb with which Hatsumi was using, in modern-day Japan.
Meirin (メイリン?)
Voiced by: Ayaka Kimura (game), Kyoko Hikami (anime)
Meirin is a cheerful, wily kitsune girl with two tails who is trying to "raise her rank" by getting close to the princess. The player of the game meets Meirin after he enters a body, the previous owner of which she unintentionally kills. To make up for it, she takes him to Fujihime.
Lala (ララ?)
Voiced by: Yukana (anime)
Lala is the monolithic AI controlling the spaceship upon which Hazuki and the others find themselves in episode ten. The ship is an "emigration spaceship" taking the former inhabitants of Earth on a search for a new home planet. None of the passengers appear over ten years old, yet they have been drifting for over two hundred years. Hazuki and Lilith discover that all the adults died in a plague nine years ago. Eve appeared in this world as Lular over a hundred years ago, and had vanished on her sixteenth birthday while fixing a malfunctioning part. This futuristic world and its characters do not appear in the game.
Tamamonomae (玉藻の前 Tamamo no Mae?)
Voiced by: Ayaka Kimura (game), Kyoko Hikami (anime)
Tamaonomae appears to be Meirin's future form as a kitsune woman with nine tails, though she exists in a different world. The world is not book world, it is named Sen-Kai, which is greater than the library. In the anime, she and Meirin may simply be alternative versions of one another; she described Meirin as her 'other self', which in context may mean that Meirin is her creation or an independent creature which fissioned off from Tamamonomae. But in the another (but same company's) game, she is a really Meirin's future form. Despite her sexual and alcoholic tendencies, is not an unsympathetic character; she has considerable insight into people and does some fairly altruistic things for some of the other characters; she restores Mariel to human form, helps Gargantua to acknowledge the truth, returns the Hat to Eve and finally seems to have taken Gargantua's henchmen in as permanent guests.
Seiren (セイレン?)
Voiced by: Terrier (game), Rie Kanda (anime)
Seiren is a beautiful, blue-haired woman who initially appears as Gargantua's ally in the anime. He describes her as a devil, but apparently trusts her, using her aid in his search for Eve. Seiren holds a grudge against Lilith, claiming that she was abandoned by her. She is most upset when they meet again on Milka's island and Lilith doesn't even remember her.
Yōko Sumeragi (皇蓉子 Sumeragi Yōko?)
Voiced by: Pomeranian (game), Sayaka Ohara (anime)
A woman who appears in a book-world that corresponds to the Russo-Japan War era. She is an intelligence agent and an expert martial artist noted for sending three colleagues into hospital during training. Yōko arrives on a train somewhere corresponding to contemporary Russian Siberia, cross-dressing as a male diplomat and attempting to link up with fellow agent Kohtaro Nanbu, codenamed "Adam", for a film containing radio codes.
Princess Mariel (マリエル?)
Voiced by: Hina Kamimura (game), Hiroko Kasahara (anime)
A princess in Ritsuko and Gargantua's world. One day, when she is placed under Ritsuko's care, she meets Gargantua and eventually develops a crush on him. She is later kidnapped and sacrificed to Lilith by Gargantua, committing suicide by poison, but is reincarnated and employed as a maid by Tamamonomae.



There is a one-book manga adaptation, Yami to Bōshi to Hon no Tabibito ~Romance, illustrated by Aya Sakurai.[2] It is a compressed version of the game's events, following the storyline that leads to a romantic relationship between the nameless main character and Lilith.
