On the Elfen Lied Fansite, a fellow fan claims - and I have no reason to doubt them, but I wanted to use qualifiers nonetheless - that an Email to Mamoru Kanbe was replied to with the news of a tentative look at a second season or reboot of the anime. According to this, he and Okamoto both are poring over international reviews and sales of the DVD's, checking to see if its even worth considering. I really don't think this person is lying, but who knows if they were misled. It sounds reasonable, especially them checking the economics of it all before proceeding. My personal suggestion : If you're a fan who's been to content to view it online, buy it outright. If there is anything to this, a spike in sales just might do the trick. And yes, at least according to this same source, Nozomi is a distinct possibility this time around, since the e-mail in question says that it was timing, and not any Nozomi hatred on Kanbe's part, that kept her out last time. Sorry not to have anything more definite, but against this possibility, I'm willing to look a little foolish if it falls flat.
