wow just really!?!?!?! the fuck? he is cool and i want to know more about him, but to still read gantz just for him is fucking dumb, just stop reading it if that's your only reason.
Everyone has their fetishes. See some people watch loli animes because of the little girls only.
Some watch mass breast animes (ikki tousen, queen's blade) just for the boobs.
But i dont really like the vamps and see them as useless extra filling.
Also if gantz was stable then it wouldnt be interesting. It would be a boring and predictable plot like in naruto. They fight, they get stronger, they fight stronger oponents and they gets stronger while getting stronger fighting and fighting to get stronger ... and they wont stop not even after their power level is over 9000! :D
Oh lets look at this from the bright side. Kurono is great at killing aliens, so why not have 2?
