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.

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.

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

If you're going in looking for a pure, logic-based mystery series? Skip this.

I was going through my manga collection and came across this and realized I'd never finished it. After hunting around, now I have. And I WISH I hadn't because all the enjoyment I had for this series is gone now. The first 2/3 of the series has SO much promise as a good mystery with really interesting characters, but the last third destroys that by veering away from logic and into the occult. Both for answers to mysteries up until that point and for the background and motivations going forward. It's stops ...
