A chartered bus crashes over a mountain pass, and twenty-three high school girls die beneath a sky that does not pause to mourn them. They wake inside a Tokyo apartment that reeks of the impossible. No injuries. No rescue. Just a black sphere humming at the center of the room — Gantz — and a countdown already ticking. Kurona Kei, the class president with steady hands and nerves her classmates have learned to lean on, is the first to understand that the clothes laid out for them are not a courtesy. They are equipment. The suits are skintight. The guns are heavier than anything a teenager should ever have to hold.

The orb flickers with an image that cannot be real. An alien. A target. The mission parameters offer no negotiation, no exit interview, no mercy. Kurona and her surviving classmates are transported onto the night streets of Tokyo where the creatures waiting for them do not cackle or monologue — they bleed. They scream. They kill with the same frantic desperation the girls themselves are just beginning to feel. The original Gantz teams were adults and delinquents and soldiers. This is a squad of schoolgirls who never saw combat before the bus went over the guardrail, and the first lesson Gantz teaches is that the suit can save your body but it cannot save your mind.

Also known as: GANTZ:G, ガンツ:G, Gantz Girls.
