Cover PageEdit

Kei Kishimoto wearing both the top half and the bottom half of an unbuttoned Gantz Suit, it is disconnect is such a way that a large amount of her breasts are visible. She is seen holding two X-guns in her Gantz Suit Gloves.


The chapter begins where the last one ended; Joichiro Nishi has seemingly been shot in the head with an X-Gun at point blank range by Kosuke Nakajima. Several seconds pass, and Masaru Kato has flashbacks of his first mission, and seeing the Onion Alien being killed by Masashi Yamada, Kiyoshi Yoshioka, Hiroshi Hatanaka and Takashi Inamori. After several more seconds pass and Joichiro is still not dead, Kei Kishimoto, Kei Kurono and Masaru are visibly confused, wondering whether it is defective, but their thoughts are cut short when Joichiro pulls out an X-Gun pistol and shoots Kosuke point blank.

A few seconds pass, with Kosuke visibly hostile after Joichiro attempted to shoot him, but before he can say anything more, his head explodes. There is a short moment of silence before Kishimoto screams and clings to Masaru for comfort, Kurono vomits and Tetsuo Nemoto looks at Joichiro in anger. Joichiro threatens everyone present, stating that anyone who points a gun at him will die, especially Masaru. Masaru asks how he isn't dead after being shot, but Joichiro states that he won't be answering any more questions, and demands that Gantz teleports him first. When Masaru asks why he would kill his partners, Joichiro calls him retarded, and asks when Gantz said anything about being partners.
