Spiral: Suiri no Kizuna is a shonen manga by Kyou Shirodaira (writer) and Eita Mizuno (art). It was published in Monthly Shonen Gangan, animated into a 25 episode series, and dubbed into English by FUNimation. Both the anime and manga are completed, the manga lasting fifteen volumes. The anime is at best an incomplete work in that it ceased production before any of the mysteries of the story were resolved. The anime has also debuted on American TV in a syndicated FUNimation Channel programming block airing on CoLours TV beginning on Monday, June 19, 2006.
Spiral is a mystery story the focal point of which is the nature of the Blade Children, those who have cat-like eyes and are missing a seventh rib bone.
The Spiral manga was licensed by TokyoPop, but was later dropped. A new manga publisher, Yen Press, has picked up Spiral and will be releasing the first volume later this year.
