Gantz: Vol. 17

It seems like every new alien creature the Gantz gang fights is just practice for another, tougher, more demented future alien battle. Every new alien means another crew of newly dead citizens, reborn as alien hunters. Except for those who survive for the next battle. And Kei is the only one who's survived since Volume One. Our anti-hero keeps adding new dimensions to his immature character, and this volume doesn't spare him a learning experience.
