is a Japanese manga series written by Kyo Shirodaira and illustrated by Eita Mizuno. It was published by Enix and then Square Enix in Monthly Shōnen Gangan from 1999 to 2005 and collected in 15 bound volumes. The series focuses on Ayumu Narumi and his efforts to solve the mystery of the Blade Children, cursed geniuses with cat-like eyes lacking a seventh rib bone. A prequel series by Shirodaira and Mizuno, called Spiral: Alive, was published in Gangan Wing and Monthly Shōnen Gangan from April 2004 to June 2008 and collected in five bound volumes.
Spiral: The Bonds of Reasoning was originally licensed for an English language release in North America by Tokyopop, however the company dropped the series. Yen Press acquired the license for Northern American release, and published the first volume in October 2007.
The series was adapted as a twenty-five episode anime television series broadcast on TV Tokyo from October 1, 2002, until March 25, 2003. The anime is licensed in Region 1 by Funimation, who released it on DVD and broadcast it on the Funimation Channel, along with the programming block on Colours TV in 2006. The series was also adapted as four light novels and a series of CD dramas.
About two years ago, Ayumu Narumi's older brother Kiyotaka, a famous detective and pianist, mysteriously disappears without a trace. Ayumu's only clue as to his brother's whereabouts is the phrase "Blade Children", the only words Ayumu could make out in Kiyotaka's final phone call. Now in his freshman year of high school, Ayumu becomes involved in solving a series of murders, crimes, and other incidents, all related to the Blade Children. Together with his school's journalist, Hiyono Yuizaki, and the unwilling assistance of his sister-in-law, Madoka, Ayumu tries to figure out who the Blade Children are and what are their goals.
The Blade Children are the central mystery of the series, known only as cursed children that few know about and are being pursued by so-called Hunters. They are distinguished by their cat-like eyes (though a few lack this feature) and by missing the seventh right rib bone. As Ayumu investigates them, he meets five Blade Children Kousuke Asazuki, Rio Takeuchi, Eyes Rutherford, Ryoko Takamachi, and Kanone Hilbert, and is tested in various ways by them. Those who meet him eventually conclude, some more reluctantly than others, that Ayumu does have what it takes to "save" the Blade Children, as they say Kiyotaka claims.
The anime series, which adapts the story through the sixth volume of the manga, compares the Blade Children to cuckoo birds, having been deposited in human "nests" to be raised, and suggesting that cuckoos go violently crazy toward the end of their lives. The manga continues the story, depicting Ayumu's discoveries about the origin of the Blade Children, their relationship with Kiyotaka, and why his older brother thinks Ayumu might be their savior.
Some thirty years ago, a man called Yaiba Mizushiro was born with one rib missing from his right ribcage. Like Kiyotaka, he excelled at everything he chose to put his mind to. When he turned twenty-three, Yaiba started his own secret society, which swiftly grew powerful enough to manipulate world events. Citing boredom, Yaiba initiated the "Blade Children Project": using in vitro techniques and his DNA, he created eighty children, and had a rib removed from each of them at birth as a mark of their relationship to Yaiba. These Blade Children were cursed in the same way Yaiba was: they would grow up as geniuses in their own right, but one day their blood would awaken murderously and take over their self-will, becoming Avatars of Yaiba. Yaiba's organization split into three parties over the Blade Children Project:
When Yaiba was thirty-six, a Japanese man came out of nowhere and easily killed him: Kiyotaka Narumi, Yaiba's counterpart—if Yaiba had been a destroyer, Kiyotaka was a creator. Yaiba had intended to remake the world literally in his own image; with his death, the Blade Children project was halted. Kiyotaka had his hands full trying to stop the Hunters from killing the Blade Children, while trying to check the Savers at the same time.
Just as Kiyotaka and Yaiba were linked, Ayumu eventually meets his own counterpart: Hizumi Mizushiro, Yaiba's younger brother, and the one who will awaken the blood of the remaining Blade Children. As Ayumu learns of this and becomes friends with Hizumi, he comes to accept that his own powers are as strong as Kiyotaka's and his role as the savior of the Blade Children, leading to a final confrontation.
Spiral: Alive is centered on a girl, Imari Sekiguchi, who falls in love with Shirou Sawamura, a boy who wants to become a detective. However, before Imari can confess to him, he unexpectedly quits school to pursue Kiyotaka Narumi. Imari learns that he also is dating Yukine Amanae, a beautiful girl at their school, and both Shirou and Imari are unaware that Yukine is actually a reluctant murderer. Meanwhile, Toru Saiki, a member of the Police Department's First Investigations Department, investigates the mysterious murders connected with Amanae and is unwilling to bring in Kiyotaka, believing that Tokyo's greatest detective is more demonic than divine. Imari, Shirou, and Saiki become involved in events that are mysteriously connected to the Blade Children. Several characters from the original series return, including Kiyotaka, Kousuke, Ryoko, Kanone, and Madoka.
The series reveals that of the eighty original Blade Children watched by the Hunters, Savers, and Watchers, thirteen have been completely erased from their lists of Blade Children. The one responsible for this had been a neutral party who committed suicide after accomplishing this. The only information about the thirteen missing Blade Children is contained in the Mikanagi File, named after Professor Isabel Mikanagi, who was responsible for their disappearance. With Professor Mikanagi's death, the file was entrusted to her associates, Yukine's parents. After their deaths as the result of a Hunter's actions, Yukine survived and currently holds in her memory the only record of the Mikanagi File.

The manga and anime adaptation have been praised for their creation of suspense and good mystery stories.[11] Although the manga has received slight criticism for its blatant display of sexual content.
