Xiaolan is one of the three main female characters in the ninja city of Kōka, where she shares a peaceful daily life with her companions Sakuya and Nemu. This tranquil existence is shattered when the Crypto Scroll, a sacred artifact enshrined in the city, is stolen, igniting widespread conflict among the ninja factions and forcing the trio to abandon their ordinary routines. The core of the story follows Xiaolan as she transitions from a life of peaceful routines to active combat, adapting alongside her friends to confront the escalating threats of a battle royale engulfing their community.

Visually, Xiaolan is defined by her distinctive hair buns, a consistent and recognizable element of her official character design. Her role in the narrative is primarily defined by her membership in the central trio. Together with Sakuya and Nemu, she is depicted as a non-ninja resident of the ninja town of Kōga who must unite her forces with the others in response to the crisis. The series, which is a short-form anime with episodes of approximately five minutes, presents a narrative that blends action with humor, focusing on how these three characters stand together against the chaos. Information regarding her individual personality traits, specific motivations, unique abilities, and personal character development across the series is not detailed in available sources. The fast-paced format of the show leaves little room for deep exploration of a single character's internal journey, with the focus remaining on the group's collective response to the central conflict.
