The Japanese retailer Mangaoh lists the 15th volume of Yu Aida's action manga Gunslinger Girl as the final volume. According to Mangaoh, ASCII Media Works' Dengeki Comics imprint will ship the volume on December 17. The limited edition of the volume will bundle Libretto! II , the second full-color booklet after the first one that was included with the 10th volume.

Seven Seas is publishing the manga in omnibus volumes in North America. (The series was previously released by ADV Manga.) The manga inspired two television anime series and an original video anime project, all of which Funimation released in North America.
