Plot
Spiral: The Bonds of Reasoning
Two years prior to the start of the series, Ayumu Narumi’s older brother, Kiyotaka, a renowned detective and pianist, vanishes without a trace. Before disappearing, Kiyotaka makes a cryptic phone call to Ayumu, leaving him with a single clue: “Blade Children.” Now a high school freshman, Ayumu becomes entangled in a series of murders and mysterious incidents, all connected to the enigmatic Blade Children. With the help of his school’s journalist, Hiyono Yuizaki, and his sister-in-law, Madoka, Ayumu works to uncover the truth behind the Blade Children and their goals.
The Blade Children are at the heart of the mystery. They are cursed individuals pursued by the Hunters, an organization that seeks to destroy them. Identified by their cat-like eyes (though some lack this trait) and the absence of their seventh right rib, the Blade Children’s origins and purpose are shrouded in secrecy. As Ayumu interacts with five key Blade Children—Kousuke Asazuki, Rio Takeuchi, Eyes Rutherford, Ryoko Takamachi, and Kanone Hilbert—he is tested repeatedly. Over time, the Blade Children come to believe that Ayumu possesses the potential to “save” them, as Kiyotaka once predicted.
The anime adaptation follows the story up to the sixth volume of the manga, comparing the Blade Children to cuckoo birds, creatures that are left in the nests of other birds and grow increasingly dangerous with age. The manga extends the story, delving into Ayumu’s discoveries about the Blade Children’s origins, their connection to Kiyotaka, and the reasons behind Kiyotaka’s belief in Ayumu’s role as their savior.
Thirty years earlier, a man named Yaiba Mizushiro was born missing a rib on his right side, much like the Blade Children. A prodigy, Yaiba founded a secretive and powerful organization. Out of boredom, he launched the “Blade Children Project,” using his DNA to create 80 genetically modified children, each marked by the removal of a rib at birth. These Blade Children inherited Yaiba’s genius but were also cursed to one day lose their self-will and become murderous avatars of Yaiba’s ambition.
Yaiba’s organization fractured into three factions over the Blade Children:
- The Savers: Supporters of Yaiba’s goals, they sought to protect the Blade Children after Yaiba’s death.
- The Watchers: Neutral observers who aimed to study the Blade Children and their development.
- The Hunters: Opponents of Yaiba, they sought to eliminate the Blade Children to prevent their potential danger.
At 36, Yaiba was killed by Kiyotaka Narumi, who became Yaiba’s counterforce. While Yaiba sought destruction, Kiyotaka worked to preserve the balance, fighting to protect the Blade Children from the Hunters and contain the ambitions of the Savers.
Eventually, Ayumu confronts his own counterpart, Hizumi Mizushiro, Yaiba’s younger brother and the one destined to awaken the Blade Children’s violent tendencies. Through his friendship with Hizumi and growing confidence in his own abilities, Ayumu comes to embrace his role as the Blade Children’s savior, leading to a final confrontation that determines their fate.
Spiral: Alive
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.
Main characters
- Template:Nihongo
- The protagonist of Spiral, Ayumu is very intelligent, but is very introverted and has a lot of self-doubt. He fears that he cannot surpass his own perfect older brother and doubts himself to the point where he no longer believes he can do anything anymore without acting like his brother. He is a talented pianist like Kiyotaka, an excellent cook, and cares a lot for his sister-in-law Madoka. He had an affection toward Madoka, but stopped when Kiyotaka married Madoka. It also said as a fact, from Kiyotaka, that Hiyono was his most important person. Ayumu is also the supposed only hope for the Blade Children and their survival. Template:Voiced by

- The infamous school journalist, Hiyono is the bubbly and energetic sidekick of Ayumu, always stuck to his side. Very clever and a quick-thinker, her confidence borders dangerously on overconfidence. She is extroverted and is Ayumu's polar opposite, serving as one of the series' few comic-relief characters.Script error: No such module "Unsubst". Her skill with computers are as amazing as her hacking abilities and she has access to over one hundred resources. She blackmails Wataya often, and is very fond of Ayumu's cooking. Hiyono is also one of the few who whole-heartedly believe in Ayumu; she also has a great deal of faith, feelings, and loyalty in him that carries on for the whole series. She attends Tsukiomi High School alongside Ayumu Narumi. Later on, she is revealed to actually be a spy set out by Kiyotaka to befriend Narumi and help him out. She has also lied about her age, she is actually older than what she has said. Template:Voiced by

- Template:Nihongo
- A Blade Child with a dual personality. He could be cute and friendly or manipulative and insane. He was very close to Eyes. He would cry for Eyes when Eyes could not when they were young, but their friendship fell apart as they grew older and developed vastly different opinions on the fate of the Blade Children. Kanone will go as far as he can to kill the people who give the Blade Children false hope, to prove to Eyes and the Blade Children they have no hope. Kanone is even willing to work with the Hunters to prove to the Blade Children that they have no hope. He does not believe that the Blade Children can be saved from their fates. Later on in the manga he regains his sanity and believes that Ayumu can save the Blade Children from a horrible fate. Just when he finally believes they can all be saved Hizumi kills him, he tells Ayumu to use his death as an opportunity. He also is an expert in fighting, he taught all the introduced Blade Children how to fight. Template:Voiced by
- Template:Nihongo
- He only appears in the manga; and is the 'younger brother' of Yaiba Mizushiro. Hizumi is the complete opposite of Ayumu in many ways. He is sinister and manipulative, though he and Ayumu got along very well upon their initial meeting. Supposedly he is a very dangerous adversary for Ayumu. He has a personality similar to that of Kanone. He is energetic and has an innocent nature about him. He always smiles and is usually well liked by people unrelated to the Blade Children, but that is actually a cover-up for his true personality; he is a desperate and lonely child who knows only despair.
