Yoriko Kichijouji[]
Her mentor and longtime friend. They met when Abiko wanted to assist her on the Sweet Today manga. Yoriko wanted to get to know her more because of her introverted personality. She found out that underneath this was an affectionate girl that yearned to be understood. After Tokyo Blade gained popularity, they parted ways, but Yoriko started seeing how that fame affected Abiko. Her concern grew until she, with the support of the actors of Tokyo Blade's stage-play, decided to talk to Abiko. In this, she saw how devastating repercussions the fame of her manga had caused her. They butted heads in conversing about which manga was better, work ethics, and Yoriko berating Abiko for using excuses to avoid communicating. In the end, they reached a common ground, Abiko stating that she just doesn't want manga she likes ruined by more popular media.

Goa[]
Abiko had a rough history with Goa. At first, she looked forward to the progress done with the initial script. Although she praised the talent and hard work of the cast members, she disliked the overall direction Goa took, despite changes being necessary to fit the theater setting. She immediately demanded a revision so that it fits within her standards.
Due to the communication between Abiko and the other higher-ups being slow and the progress on the revisions still lacking, she entertained the idea of Goa being fired from his position as a scriptwriter. Though, as planned by Aqua Hoshino, Raida Sumiaki intervened and suggested she shouldn't do so. She accepts on the condition that they maintain clear-cut levels of communication. Goa and Abiko voice-called in real time to create something acceptable in her eyes. In a twist of fate, Abiko was ecstatic about their final product.
