Description
Akitoshi Okazaki is a minor but memorable character in the Gantz narrative, introduced as a member of the Tokyo team during one of their missions. He is a 28-year-old hikikomori, a recluse who has withdrawn from society. His lifestyle has left him overweight and near-sighted, requiring him to wear thick glasses. He has a short, stocky build with black hair cut in a simple bowl style. True to his self-image as a military enthusiast, he wears large army-style clothing including a vest, trousers, and heavy boots, notably opting not to wear the protective soft suit provided by Gantz.

His background is rooted in extreme social isolation. Before his death, Okazaki spent all his time playing violent video games and military-themed eroge, eating junk food, and collecting what is described as army loli figurines. His death was anticlimactic and ironic, occurring not in a battle but when he choked on his own food while playing a video game. Following his death, his data was copied to the Tokyo Gantz room, forcing him to participate in the alien-hunting game.

In terms of personality, Okazaki is a complex and deeply flawed individual who displays a rapid and disturbing evolution once the mission begins. Initially, he is quick to follow anyone who projects confidence, latching onto Musō Tokugawa who pretends to understand the situation. When Masaru Kato proves Tokugawa wrong, Okazaki immediately shifts his allegiance. He is obsessed with guns and military tactics, a passion he unsuccessfully tries to share with the stoic Juzo Togo.

As the mission against the aliens progresses, his more sinister traits surface. He is cowardly at first, choosing to hide from the aliens, yet simultaneously encourages Kei Kurono to kill. This gives way to a sadistic and cruel nature; he takes pleasure in shooting the corpse of the Rowdy Alien and tortures the only alien he manages to subdue by shooting it apart bit by bit. This behavior points to a psychopathic lack of empathy and a complete disconnect from reality, likely fueled by his years of playing violent games. He is also profoundly non-self-aware and overconfident, believing his knowledge from video games translates to real combat, which leads directly to his death when he charges recklessly at the immense Daibutsu Alien.

His role in the story is that of a cautionary example. He serves to illustrate how the Gantz game attracts and ultimately destroys broken individuals. He has no meaningful development or redemption arc, as he dies in the very first mission he participates in. His key relationships are superficial and transactional; he briefly allies with Tokugawa for a false sense of security and tries to befriend Togo, who ignores him. His interactions with Kurono are marked by his encouragement of violence, showcasing his corrupting influence. His notable abilities are not physical or tactical but rather a disturbing proficiency with firearms born from his virtual experience, which he uses not for efficient combat but for cruel, drawn-out torture.
