Gojo-kun is the older brother and manager at Number One Produce, who takes his work very seriously. Despite being her older brother, she calls him "Gojo-kun" and treats him like a "company animal." They live in a two-bedroom apartment near Shinjuku that they can't afford on their salaries alone, so they rely on help from their parents to pay the rent. Although Gojou is dismayed by Chitose's unprofessionalism in not reading the original light novels when auditioning for her role or after it was assigned, he believes that it's a case-by-case basis as to whether she should read the source material since giving a good performance for the anime is separate from being able to give a good performance for the manga. Gojou originally worked as a voice actor with the catchphrase "the noble son of bass," but he quit after one leading role in an anime that failed to sell, so he switched to backstage work. He later became Nanami's new manager and stopped managing Chitose. In "Girlish Number Shura," Gojou wears glasses.
