I can see where the manga is going
After seeing Kei get pwned (sorry for my lack of class) by Oni Boss I feel it's safe to say that the GANTZers are screwed.
No karate pimp and no Kurono to take out the enemy.
Prediction:
Reika will get worried and go to Kurono, Old man gets mad and goes after oni boss.
Oni boss rimps his arms off and beats him with his own body parts, then he uses the rest of his body to take out the rest of the GANTZers while Reika runs off with Kurono.
Man, Mrs. Cleo has got nothing on me!
Seriously that would own.......
