Spiral is one of favorite animes. It's a very good mystery/detective anime. Many parts of the series are just amazing and suspenseful. After Watching the first episode I had to watch the next. This series just leaves you thinking "How could anyone figure his way out of this!?!?" Unfortunately the series leaves many questions unanswered but all the answers are in the manga and the is another manga coming out that will further explain but its not done yet.
