This would be the perfect time to create a special Gantz All-star mission...
We could have it begin when Kurono is killed by Blondie Vamp.
He is sent to a different room with a white ball.
The participants are...
The Sniper from the Buddha Mission
Lara Craft lookalike (Sie) from The Buddha Mission
The three main vamps that didn't survive the attack against Izumi
Karate Fighter that got his neck broken in the Buddha Mission
One of Kurono's friends that were killed during the Chibi Alien attack
Onion Alien Dad (Pisses his pants when he sees Kurono)
Ippo from hajime no ippo. (Boxer that was killed in the ring from a fatal blow)
The sub bosses are made after other favorite manga artists, including Akira Toriyama...:)
Now if someone could only draw it in the same quality as the actual manga...
