Two highly experienced authors who until now have done a completely different genre. And from the first chapters it seems that this manga has great ambition to become a classic adventure shounen, I can't wait to see if it can keep them, when I say classic I don't mean banal but successful.
I find it interesting that Cool Kyoushinsha (the designer) in addition to his personal style here adopts a style that is also close to that of Amahara (here only as a writer).
