After having been following Gantz Since 2006 I really felt an extreme happines when i saw that Gantz was going to release a new spin-off, but now, after finished this Story, i cannot hide my dissapontment; it was supposed that the magaka was a Master after created one of my favorite manga, but it looks like he tried to add "politically correct" characters, i don't have any problem with female characters but yes i have with a poor construction on their story, most of the decision in the story were made with no logic, even the name of the principal character is the F*** same than in Gantz.
In conclusion, bad decisions for a good intentioned spin-off.
