Rice

Rice the Dog is present during the first few Gantz missions Kurono and the gang go on and is one of the animal members of the Tokyo Team. He never gets any points because of "too much tongue/tail wagging". He is present in every mission until he is replaced by the panda. Rice was abandoned on a walk by its owner, who ran away from him. When trying to chase its owner it was hit by a dump truck, killing it and sending it to the Tokyo room for the first time, surprising its only veteran hunter Joichiro Nishi who expected it to die just like all others, but being surprised the first four times the dog survives just like him.

Nishi then ignores the dog for their following missions until finally three others survive who inquire about him, with Nishi flatly stating he always survives, which held true until after Nishi's own death.

Rice is an enthusiastic, friendly dog. Whom is pretty aware of the things that happen around him. When Gantz starts scoring people he eagerly waits for his own only to be berated by him for not doing anything while showing him his score of zero points which upsets Rice. Rice's most characteristic trait is that he appears to be a butter dog, trying on more then one occasion to lick Kei Kishimoto's vagina. Making Kurono wonder if he used to belong to some lonely housewife who trained him to do so.

In the anime, Rice was also able to warn the other players that there were more enemies to fight, such as when he started barking at the smaller statues during the Buddhist Temple mission. All in all out of all the humans he interacts with he seems the most fond of Kishimoto. The anime shows her putting his Gants suit on him and hugs him when she learns he survived and in the manga they even appear on a number of chapter covers together.
