Didn't see this coming. Nothing wrong with spontaneous kissing though.
The Tokyo is transported into space inside the alien mothership. A guy comes around to lead the team to the Americans, and on the way the team sees a bunch of Gantzers smoking pot, having sex, posing with naked alien prisoners. The Gantzers also force the aliens to have sex and a man is raping a female alien. The female alien shakes off the man but is shot to death by the Gantzers. Having seen enough, the Tokyo team attack the lowlife Gantzers but their guide tell them to keep going. On the mention of sex and virginity, the new hot girl in the group sets her eyes on the manly Kaze and both discover that the other is a virgin.
The Tokyo Team arrive at the base of some escalators and meet up with the Americans. The guide and the Americans claim that they can transport the Gantzer to a place where they can find "the answer" and truth of the universe. Kato and the team agree to go on the mission, and the transmission starts.
The whole point of this chapter is to show some naked bodies, sex and rape. The story didn't need this chapter, but I guess this was just to remind us that Gantz is a "mature" series. Kaze and the new hot girl (don't remember her name) was surprising, but relationships between Gantzers don't really last, especially without Gantz' revival ability. The real interesting chapter will be the next one where the team goes to the place with "the answer" lol. Kurono #2 was conspicuously missing from this chapter. I don't remember what happened with him after Reika died, and I assumed that he was still with the team. Weird.
