Kyouko Sakurami attends Touhou Seika Girls' School as a first-year student in Class 1-1. She holds the position of left fielder on the school baseball team, joining as its seventh or eighth member. Upperclassman Tomoe Tsukubae recruited her, and Kyouko accepted instantly without hesitation due to her intense admiration for Tomoe—an admiration extending beyond typical friendship into clear indications of deeper affection.

During team strategy disagreements, Kyouko consistently aligns with Tomoe, especially favoring Tomoe's offensive approaches. Her primary motivation for playing baseball revolves around spending time with Tomoe and earning her recognition. However, Kyouko demonstrates limited natural aptitude for the sport. A notable fielding error during a practice game deeply affected her emotionally.

Despite her baseball challenges, Kyouko generally maintains a cheerful disposition. Her emotional state remains closely tied to interactions with Tomoe and her own perceived performance in baseball.
