Description
Kato Masaru is a central figure in the Gantz narrative, distinguished by his strong moral compass and deep-seated altruism, traits that stand in stark contrast to the often brutal and self-serving world he is forced into.
Standing at an impressive 192 centimeters, Kato possesses a large and somewhat intimidating physique. Despite his formidable appearance, his personality is characterized by gentleness and a profound pacifism. He is known among the Gantz teams as a gentle giant, always looking for alternative ways to resolve conflicts without resorting to killing and constantly striving to ensure that every player returns from a mission alive. This aversion to violence often hinders his performance in the deadly game, as he typically favors using less brutal tools like the capture gun over lethal weapons.
Kato's deeply ingrained sense of justice and heroism is rooted in his childhood. He lost both parents at a young age; his father was a firefighter, an occupation that inspired Kato's own willingness to risk his life for others. Orphaned, he and his younger brother, Ayumu, went to live with relatives, where they faced mistreatment and were made to feel like freeloaders. This difficult home life forged in Kato a fierce protectiveness over his brother and a singular dream of saving enough money to rent an apartment where the two of them could live together in peace.
A chance encounter in a subway station with his childhood friend, Kei Kurono, seals his fate. After seeing a homeless man fall onto the tracks, Kato immediately jumps down to help. He calls out to the reluctant Kurono for assistance, and together they manage to get the man to safety. In a tragic turn of events, the two friends are hit by an incoming train and killed. Instead of dying, they are transported to the mysterious room containing the black sphere known as Gantz.
In this new reality, Kato continues to act on his principles. During his first mission, he tries to protect a small, child-like alien, showing his innate empathy even for targets that others see only as enemies to be eliminated. He quickly becomes a moral anchor for the group, and his natural authority often pushes him into a leadership position, despite his personal struggles with the violence the game demands. His relationship with Kurono is central to the story. While Kurono initially appears cynical and self-absorbed, Kato serves as a reminder of the better person Kurono once was in middle school, a person Kato had always admired.
Kato's journey is marked by sacrifice and a stubborn refusal to abandon his humanity. He dies during a mission at a Buddhist temple, but is later resurrected by another player who had accumulated enough points. Upon his return, his primary motivation shifts to reviving Kurono, who has since been killed. This goal drives him to hunt down a powerful, one-hundred-point alien, a quest that sees him partner with Anzu Yamasaki, a member of the Osaka Gantz team, with whom he forms a significant bond.
Throughout the escalating hostilities, including a full-scale alien invasion of Earth, Kato remains a heroic figure, rescuing civilians and fighting alongside his comrades. In the final battle, he works alongside Kurono to defeat the alien leader, creating the crucial opening his friend needs to land the decisive blow. After the conflict, he is last seen having survived the ordeal and reuniting with his younger brother, having finally fulfilled his role as a protector.
