Dinosaurs. Seriously, can the frantic world of Gantz get any more scary? How about a giant doughboy with crazy fangs and a strange outie bellybutton? Yeah, it's not just scary; it's a very strange world for Kei and whomever is unlucky enough to die when Gantz is gathering random people and animals for a new mission. At least this time the Gantz crew have a sweet new weapon! It's an awesome uni-motorcycle thing! And one of the characters uses a massive space samurai sword. It's Gantz! And it's totally rad.
