Last Gasp has been publishing the new translation of Barefoot Gen. Yesterday I picked up the two latest volumes, 5 ands 6, at their booth at WonderCon in San Francisco.
These two volumes have never before been translated into English. There will be ten volumes in all when the series is over.
It will be a little while before they hit stores so dig out your copies of volumes 1-4 and re-read them, then get the newer ones.
