Koushun Takami, author of the original novel from which the manga and movie derive, has not released any new written works in a decade or so.
I'm guessing his finances are dwindling, so he's going back to what works.
BATTLE ROYALE: ANGELS' BORDER debuts in print from the VIZ Signature imprint, is rated 'T+' for Older Teens, and will carry an MSRP of $12.99 U.S. / $14.99 CAN. The new single-volume release reveals for the first time in graphic novel form the full story and grisly demise of the girls in the lighthouse that was so memorably featured in the original BATTLE ROYALE book and live-action film. BATTLE ROYALE: ANGELS' BORDER features artwork by Mioko Ohnishi and Youhei Oguma.I remember when the original was considered unreleasable in the US, and now every new young-adult franchise wannabe is basically doing a variation on it. I certainly can't begrudge Koushun Takami for wanting a few more royalties.
