Quan is one of the main characters of the anime Kizuna no Allele, holding a central role in both seasons of the story. She is a student at ADEN Academy and a member of PathTLive, the virtual artist collective around which the series is built, where she is grouped with her fellow main characters Miracle, Chris, Noelle, and Riz. She is also associated with the alias marumaru. In terms of appearance, Quan is known for her very long maroon hair and red eyes, a striking look that strongly shapes how others perceive her.

Her personality is defined by the contrast between that appearance and what lies beneath it. Quan has grown tired of being judged by her looks alone while her inner self goes largely unnoticed, and this has left her with a hesitant, low-energy demeanor. Her core motivation grows out of this experience: she wants to be recognized for who she really is rather than for her exterior. This desire underpins her role in the story, where her personal journey is tied to the group's efforts to express themselves and pursue their ambitions as virtual artists.

Within the series, Quan's relationships with her PathTLive companions form the main context for her growth, and her development across the two seasons centers on the question of identity and on being seen for one's true self. As a member of a virtual artist collective, her notable abilities are connected to performance, including her work toward the stage alongside her unit, rather than to any supernatural powers.
