Gantz Wiki

Gantz is the name of the man inhabiting the Black sphere in the Tokyo Room. He is a clone of a random person used to provide an interface for the Hunt System. Every Black Sphere around the globe is controlled by a clone of the same unknown man.


Gantz is completely bald and pale, with an average height.


Gantz's personality as a person is unknown, however when inside the Sphere his humour is dark and acidic, calling the Hunters pejorative names such as "Bitch", "Titties" and "Homo" in their profile screens, and often commenting on how poor was their performance in the Game when giving away the points. Whether this trait is shared by every clone or it is just the Tokyo Clone sense of humor is unknown.


The man that resides inside the black sphere of the Tokyo Team is called Gantz. Other teams refer to their person differently.

As of beginning Chapter 297 - "Stirrings Within The Black Sphere", "Gantz" is seen fully for the first time appearing outside of the black sphere. After a mission everyone leaves, but Reika forgets her clothing so she returns. She finds Gantz outside of the ball. Having earned enough points for the hundred point menu after the last mission, she asks Gantz to use it to create a second Kei Kurono (a copy of the original) for her own selfish reason. He agrees and does this.
