Parker Dōmeki, the sole member of Shibahama High’s Audio Club, initially joined to explore its repository of archived audio files. Pragmatism led her to yield a portion of the club’s storage to the student council, a decision reflecting her practical nature. She extends this resourcefulness to a transactional partnership with the Eizouken club, serving as their audio consultant by providing sound design expertise in exchange for shared storage in their clubroom.

Her appearance features dark skin, ochre-colored hair with side bangs, gray eyes, and the standard school uniform. Though her interactions with Eizouken members remain businesslike, she balances these exchanges with cooperative technical contributions, all while upholding a quietly reserved presence.
