The North American manga publisher Seven Seas has announced that it has licensed Yu Aida's Gunslinger Girl action manga and Masayuki Takano's Blood Alone vampire manga. The publisher will release the first six volumes of Gunslinger Girl in two omnibus volumes starting in February of 2011, and then release single volumes starting with volume 7. There are currently 12 volumes in Japan.

Seven Seas will release the first three volumes of Blood Alone in one omnibus volume in May of 2011, followed by single volumes for the remaining volumes. There are six volumes in Japan currently.

ADV Manga had previously published Gunslinger Girl, and Infinity Studios had previously published Blood Alone. Seven Seas will give both series new translations and lettering.

Update: Seven Seas also announced that it will release Strawberry Panic! The Complete Manga Collection, which will contain "both volumes of the manga, plus two all-new previously unreleased chapters," and the first Venus Versus Virus Omnibus book (with three collected volumes) this October. The three-volume Hayate X Blade Omnibus 1 and three-volume Inukami! Omnibus 1 will follow in November. Rachel Roberts' Avalon: The Warlock Diaries series will get a complete, three-volume omnibus collection in December.
