Gantz, Volume 20

Life is confusing for Kei Kurono. Once a conscripted fighter of invisible alien invaders, a strange turn of events finds him back in his old life. Having no recollection of his warrior days, the sense of something missing flickers in the shadows of his memory. But despite a missing past, Kei's present is still a matter of life and death as he becomes the prey of a band of stylish vampires. Surviving by his wits alone, trying to stave off his third death, who will come to Kei's aid - his long-lost brother or the former comrades-in-arms he no longer remembers? Hiroya Oku's Gantz is a dark, violent, and shockingly adult manga, selling over fifteen million of copies in Japan and inspiring a popular anime franchise, video game, and live-action film.
