Storyline

Ayumu Narumi, a contemplative freshman at high school, finds his life changed when he is blamed for a girl's fall from a school building. Using only keen observation and his stunning talent for deductive logic, he soons figures out the truth behind the incident and clears himself, to the amazement of his Police detective sister and Kiyono Yuizaki, the enterprising Journalism Club president. That case proves to be the start of a strange rash of crimes that Ayumu learns is the doing of the mysterious Blade Children. Over the objections of his sister, he investigates these crimes with the help of Kiyono who has considerable guile of her own. Meanwhile, the Blade Children learn of their new opponent and set about to stop him in form of deadly logic puzzles that will take all of Ayumu's brilliance to thwart. All the while, he uncovers dark secrets about himself, The Children and his connection to them. Written by Kenneth Chisholm (kchishol@rogers.com)

Overview
9 October 2006 | by (United States) – See all my reviews

Summary: Spiral: Suiri no kizuna or Spiral Bond of Reasoning in America, is a mystery anime revolving around Amuyu Narumi and his search for answers about the mysterious organization known as the Blade Children. With the help of the peppy Yuizaki Hiyono, head of the school newspaper, they uncover startling evidence and piece together mysterious and murders with just the smallest clues. This series contains 25 episodes.

Appropriate Odience: When it comes to blood, Spiral is pretty good, though there can be some violence and swearing. Recommended for older viewers, children may find the puzzles and logic and bit boring.

Rating: 9 out of 10 I personally really liked the series. There is character development and lots of twists and turns. The logic behind the plot is amazing and keeps you hooked. Though there are a few quirks here and there, they aren't that noticeable and add up to a great mystery anime.
