Gojou Karasuma

Chitose's older brother and manager at Number One Produce. He takes his work very seriously and therefore has difficulty dealing with his younger sister. Despite being her older brother, she calls him "Gojo-kun" and treats him like a "company animal."

In the novel, he lives with Chitose in a two-bedroom apartment near Shinjuku. It is not a place that Gojo and Chitose can afford to live in on their meager salaries alone, and they manage to pay the rent with help from their parents.

While he is dismayed by Chitose's unprofessionalism in neither reading the original light novels when auditioning for the role nor after the role has been assigned to her, Gojou also believes that it is a case-by-case basis as to whether she should read the source material since it is a separate issue as to whether she can give a good performance for the anime or not.

Gojou originally worked as a voice actor with the catchphrase "the noble son of bass," but although he had one leading role in an anime, the product ultimately failed to sell, so he quit and switched to backstage work. During his voice acting days, he was a colleague of Koto Katakura.

Gojou later becomes Nanami's new manager and stops managing Chitose.

In "Girlish Number Shura," he wears glasses.
