After watching the FUNimation dub (anime) adaption back in 2009, I always wanted to dive deeper into this story, so I finally picked up the manga. 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, and sad.

Story
The storyline is just very nice, very well-done. Shirodaira did a good job. Even though Spiral is an action and a mystery manga, there are many emotional aspects to the plot as well. It has a good amount of suspense and tension, but not a ridiculous amount that makes your brain freeze up, just enough to keep you on the seat. In addition, the many tiny comic relief moments are very well placed, so Spiral, with all its darkness, is still rather light, but not inappropriately so. But, the most outstanding aspect to me was that between all the action and humor, we have many of those...I can't even describe it, but, BEAUTIFUL delicate moments that touch your heart.
Story: 10/10

Art
The art is up to par. I love Eita Mizuno's style and I wish that he would do the artwork for some other manga as well since I just fell in love with his art. Everything is water-colored and the drawings are always very nice. I bought one of the Spiral Artbooks. For art, 8/10.

Character
All of the characters are very likeable. Because of the wide cast of characters it tends to be hard to tell each character apart. There is no good or evil in Spiral - all of the characters have goodness and darkness in their personality, especially the main character.... which makes them more human-like to the audience. 10/10.

Enjoyment
Spiral is a very enjoyable read. The suspense and tension mixed with comedy and the nice scenes and both the physical and mental battles all add to the enjoyment. The psychological aspect of the manga is something real. You have to pay close attention when your reading dialogue between characters, which is what I LOVE! 10/10

Overall
Spiral was an amazing journey. It made me laugh, cry, and even made me learn new things. Spiral has comedy, action, mystery, foreboding, and even some romance that makes you smile. 10/10
