User Reviews

Overview

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.
