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.

Spiral: Suiri no Kizuna can be almost what you would call reading 15 volumes of bliss. The mix of excellent artwork, a mind-boggling storyline, fascinating characters and plot twists that you would not have expected all work towards creating the dictionary definition of an 'enjoyable read'.
Spiral's storyline is one of the decisive elements that keep it apart from your usual run-of-the-mill manga. While it begins on a rather lackluster note, seemingly appearing to be a murder mystery, the plot quickly develops into one that leaves you with many questions asked, and begging for the answers to come quick. The mystery behind the existence of the ...

This is my first review for one of my favorite manga, please cut me some slack guys. :D

Spiral Suiri no Kizuna has been an amazing read for me, in every way. There are very few lacking aspects in this manga. Upon finishing it, it left me both happy, sad, and thoughtful, which most mangas fail to do. If Spiral were a song, I'd say that it begins mysteriously and ends both beautifully and in a simple way.

The storyline is just very nice, very well-done. Kyo Shirodaira-sensei did a good job. Even though Spiral is an action and a mystery manga, there are many emotional aspects ...

Mixed Feelings
Kiyotaka Narumi is a brilliant pianist and detective who disappeared two years before the events of Spiral: Suiri no Kizuna. "I went to find the Blade Children," is the only message he left behind for his wife, Madoka, and his younger brother Ayumu. Though Ayumu is gifted in both logic and piano, he has grown apathetic due to constantly being in Kiyotaka's shadow. A murder at Ayumu's school and a new message from Kiyotaka drag Ayumu into the deadly mystery of the Blade Children.

Character: 8 (Very Good)

The characters were my favorite part of this series and were why I continued reading until the end. ...
