He has short brown hair and is the average height of a teenage boy.


Like the person he was cloned from, Kei Kurono, Kei is brave, caring and relentless, never failing to try and do the right thing, and to fight for the people important to him. Kei is torn by his love for Tae and attraction and resentment towards Reika for creating him.


Kei was born out of the obsessive love Reika held for Kei Kurono. After being rejected by Kurono, who was in love with Kojima Tae, Reika seized an opportunity to "revive" Kurono from the Gantz memory, creating a second Kurono.


Italian MissionEdit

Kei was created after the conclusion of the Italian Mission. Reika had accumulated 100 points, and initially planned to resurrect Suzuki, but Gantz seemingly malfunctioned, and Suzuki was not resurrected. After the team left the apartment, Reika returned, having forgotten her clothes, and encountered the man inside the Gantz ball. He asked her who it was she wanted to resurrect, and Reika decided to seize this opportunity to create a Kurono of her own. Kei initially vehemently rejected Reika, declaring that he was still in love with Tae, and that she was insane.

Kei rushed home, only to encounter his original self planning to call Tae. Realising that there was no place for him there, he returned to Reika's apartment. He spent the night on her couch, and in his rage, attempted to rape her. After she gave her consent however, Kei merely apologised and went back to sleep. Kei later sought out his original self, who nonchalantly stated that there was no problem. He (the original) would stay with Tae, and Kei (the clone) would be free to be with Reika, thus "everyone would be happy." Kei resigned himself to his fate, and went to live with Reika. Reika even went so far as to quit her job in order to be with Kurono, and asked him to marry her (he told her no, since he was only 17 and not legally allowed to marry).


When the Giant Aliens invaded Earth, Kei and Reika fought them, with the assistance of several other Gantz hunters. Kei and Reika, along with Kato, Kaze and Sakurai were forcibly conscripted by Zaibatsu executives who had hijacked several Gantz balls to a reconnaissance mission aboard the giant ship. The team met with heavy casualties, and were eventually transported out again.

United Rescue ArcEdit

After the mission, Kei, Reika, Kato, Kaze and Takeshi head to the Gantz room in hopes of answers and a way to fight the invasion. There, they find the man operating Gantz and Nishi. Gantz offers to help them in any way possible, and Kei asks if it's possible to make contact with other Gantz balls. Gantz helps him transmit a message, and Kei asks for volunteers to undertake a rescue mission aboard the ship, in an attempt to save as many captured humans as possible, using intel from the American Gantz team.

The new team manage to rescue many humans, but their progress is hindered when Gantz is hacked, and they are transferred to somewhere in the Giant city. Here, they encounter vicious insectoid aliens, which kill one of their members. The team manage to take out most of them, leaving only one large monster. Kei volunteers to stay behind, declaring that unless the monster was dealt with now, it would come back and kill them all later. Part of his motivation for remaining behind however, is proving that he is as good as the other Kurono. Reika refuses to leave Kei however, returning despite Kei and the rest of the team's wishes. She arrives just in time to save Kei, but he angrily tells her to go away, and that he wishes he could see Tae one more time.

Kei is knocked out in the battle, leaving Reika to fight the monster alone. As Kei comes to, he sees the creature dead, and finds Reika dead as well. Maddened with grief, Kei desperately attempts to resuscitate her, weeping all the while as he realises that he did love her after all, and regretting the harsh words he had spoken to her before her death. Realising that she's gone, he takes her body to the rest of the team, to be cremated.

The Final ChallengeEdit

With the Giants all but defeated, Kei and the remaining rescue team are taken to a "room of truth" where they encounter the God Aliens. These aliens reveal that they sent Earth the Gantz technology as a means of protecting them against alien invasions. The aliens go on to show their disdain for humanity and declare humans to be nothing more than "things." Kei angrily objects, and to prove their point, the aliens resurrect Suzuki, Sakuraoka, Kishimoto, and Reika. Just as Kei gets a chance to reacquaint himself with his lost loved ones, and a chance to finally tell Reika that he loves her, the aliens kill all four of them again. Maddened with grief and rage, Kei tries to lash out at them, but is killed as well. Kato attempts to avenge his friend, but is held back by the rest of the team.

The aliens state that Reika will be reborn in two years as an American woman, and that Kei will be reborn twenty years later as her son.

Abilities & SkillsEdit

Like the real Kurono, Kei is an extremely skilled Gantz fighter. He is competent in the use of almost every weapon available to him, including the X, Y, and Z-Guns, the sword and the chopper.
