About this title

Synopsis

Ayumu Narumi has lived all his life in the shadow of his famous detective brother, Kiyotaka. However, Kiyotaka disappeared two years ago, leaving behind his wife Madoka and Ayumu himself, along with a cryptic message about the "Blade Children." One day, a girl at Ayumu's school suddenly dies. What seemed like a suicide at first glance turns out to be a murder, and Ayumu is the prime suspect. While investigating the person responsible for framing him, he discovers that the mysterious Blade Children are involved—and they somehow know Kiyotaka personally. Ayumu soon finds out just how dangerous the Blade Children are and learns that, in reality, he and Kiyotaka are intertwined more closely than he had ever believed. [Written by MAL Rewrite]

Main characters

Ayumu Narumi284 fan favorites
External profile
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. Ayumu is also the supposed only hope for the Blade Children and their survival.

Eyes Rutherford109 fan favorites
External profile
The world-class pianist, he is second only to Kiyotaka Narumi, Ayumu Narumi's older brother. He is seemingly cold-hearted but definitely not heartless (he brought Rio melons when she was stuck in the hospital). He cares a great deal about the Blade Children and would do anything for them to survive at all costs. He is exceedingly loyal to Kiyotaka's words and seems to believe in Ayumu the most out of all the Blade Children. Eyes knows much more than the other Blade Children do, holding secrets he keeps to himself. He is one of the first targets of assassination by the Hunters (after Sayoko) but outwits them at a charity concert with the help of Ayumu and Kousuke. He and Kanone have a some sort of bond, even though the friendship between Eyes and Kanone seems to shatter once he learned of Kanone's betrayal of the Blade Children. Eyes appears to be the leader of the Blade Children but he treats Kanone as either an equal or even an older brother. (Source: Wikipedia)
Hiyono Yuizaki88 fan favorites
External profile
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. 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 and loyalty in him that carries on for the whole series. She attends Tsukiomi High School alongside with Ayumu Narumi. (Source: Wikipedia)
Rio Takeuchi44 fan favorites
External profile
The "midget" of the Blade Children group, she resembles a 13 year old child rather than her actual age, 16. Rio may seem small, but she is actually older then both Kousuke and Ryoko, as revealed in Spiral Alive, and the Bonds of reasoning manga. Although Rio appears to be the most innocent of the Blade Children with her cherubic features and size, she is actually very shrewd and calculating, and is one of the more dangerous of the blade children. Rio knows how to create bombs, devise difficult plans and kill those she considers her enemies. She is extremely intelligent and is able to escape from any sticky situation, no matter how small or tight it is. She is very straight-forward and has a crush on Eyes because he gives her 'netted pattern' melons (her favorite food). Like Kousuke, she will not hesitate to kill people if she has to.

Kousuke Asazuki39 fan favorites
External profile
The most arrogant, aggressive and most violent of all the Blade Children Kousuke is usually the implementor of assassinations. Kousuke is very strong-willed and stubborn, choosing to fight the Hunters head on rather than hide from them. He is impulsive, impatient, and tends to resort to physical violence over verbal negotiation. He is not afraid to kill and does not really trust Eyes, resulting in arguments between them. While Rio calls him stupid, in reality Kousuke is very intelligent; after skipping most of elementary school, he still manages to catch up to secondary school level from reading and learning from books. Kousuke also left middle school after a run in with a teacher. Kousuke may also have some romantic feelings for Ryoko. (Source: Wikipedia)
