Well, this is a pretty fast turn around. Shaman King Flowers Volume 1 will release in Japan on August 10th, 2012. Yup, that’s really, really soon. So let’s figure out how that chapter breakdown works by page count:
Chapter 1: 45 pages
Chapter 2: 41 pages
Chapter 3: 40 pages
That right there is 126 pages. So let’s assume that chapter 4 is another 40 pages… which would bring the total page count to around 166 pages. That’s right around the number of pages for an average volume. So it’s unlikely that Hana’s Epoch would be included (it’s in the Mentalite anyways!). Maybe some little extras, nothing too huge I don’t think. Probably the color opening pages will be included. They’ve included them in all of the Jumbors and in Shaman King Zero volume 1.
And it comes out on the same day as JumpX with chapter 6. Cool to know. Though, it’s a bit weird they didn’t include this announcement with Shaman King Flowers chapter 3….
