Hiroto Sakurai
He is a psychic who receives instructions on how to unlock his latent powers from Sakata after attempting suicide. He is then encouraged by Sakata to kill his bullies who sexually abused him with the use of his powers, which he does. However, he later regrets it, realizing how it feels to be a murderer. When he and Sakata witness Izumi's Shinjuku massacre, he insists in trying to stop Izumi and convinces Sakata to join him, arguing that it is a good opportunity to redeem themselves for the murders they committed themselves. While they do put up a good fight, Izumi still does manage to kill both, leading them to Gantz. A phenomenal learner, he masters his abilities rather quickly. He dies in the fight against the Flame Oni, but is revived by Sakata. Gantz calls him "Cherry", taken from the Japanese Sakura and which is his online handle. He has a girlfriend named Tonkotsu who he first met after he murdered the people who abused him. With her, he is seen trying to catch murderers using his psychic powers, in order to further redeem himself. After the mission in Osaka, Gantz names him "no longer a Cherry (Cherry is also the way Japanese address a virgin boy. No longer a Cherry in this term means that he is no longer a virgin)".
