Mujina Bandits Arc
When Boruto Uzumaki and Mitsuki arrived at their cell, Kamata wasted no time telling them that as newcomers, they go to the bottom bunks of the cell, and promptly stole Boruto's toothbrush while he was moving his things, claiming nothing that is left about belongs to anyone. When Mitsuki stole his magazine instead, Kamata exchanged it back for Boruto's toothbrush.

Later, when Boruto approached Doragu for information, the inner-boss of the prison agreed to help if Boruto got him the light bulb from a watchtower. Everyone began making bets on if Boruto would succeed and Kamata made one himself. Much to his dismay, he stumbled and accidentally bet on Boruto to succeed. Much to his joy however, Boruto succeeded. Later, Kamata gave his winnings to a guard for safekeeping, for a small cut. He also asked the guard to mail a letter for him.

Later, Kokuri was transferred to Kamata's cell. Soon after, they learned that one of the guard's special access tags was taken, forcing everyone into lock-down. Boruto and Mitsuki revealed that on the day Boruto was sent to the medical wing, Kokuri was attacked by an inmate, the same time an access tag went missing. Thus, they concluded that it must have been by one of the cell-mates. While interrogating everyone, it came out that Kokuri was a deserter of the Mujina Bandits and had stolen a lot of money from them. Ultimately, they discovered that it was Arai who took the tag. They quickly turned in the man to avoid punishment themselves, and Kamata decided to be nice to Kokuri, admiring that the man was once part of the infamous gang, also hoping to get some of the stolen money.
