I do not know if there is any necro rules, but I just received my copy about an half hour ago (what would now be an hour and a half ago). I thought I'd post what is in there. Spoiler tags, take note I only skimmed and read a few pages..
(Hm, took longer than I thought... Anyway, that's the first story. Might post the others later... Do not know how correct it is, but should be mostly. The stories length from shortest to longest are: Miroku, Ageha & Abyss Date, Frederica and then Kagetora (almost 100 pages).)
Van's diaries are funny though... To end this post though, some timelines.
Thank Shedge, (the Psyren Novel haven't reached my bookstore as of now....)
Looks like I'll need to order one online, and try to fill in any gaps shall I find extra notes about that may enhance the main story plot that was never featured in Shonen Jump.
A little late but wasn't there a second novel?
Yes there was. Some info here and in the subsequent posts (including the following page), but I'm not too sure if there is more info on the contents apart from that.
