Hello This my first time writing on this page i found something interesting its seem that Sheuisha has decided to follow that series heres the info:
In November 2011, Shueisha announced the serialization of a sequel, Shaman King: Flowers (シャーマンキング 花Shāman Kingu Hana?), to start in their magazine Jump Kai in April 2012. It will focus on Hana Asakura's development as a Shaman.
