Souffle embodies the Sheep (Goat) of the Chinese zodiac, serving among twelve animal spirits guarding the Novel Worlds. She wields a mystical compact that detects metallic materials, enabling her team to pinpoint corrupted elements during missions. Reserved yet nurturing, she offers steadfast emotional support to allies while balancing her distinctly feminine presence against more combat-driven teammates.

A subtle undercurrent of romantic tension with fellow member Pakaracchi surfaces periodically, though the narrative prioritizes collective objectives over individual relationships. Her pivotal character moment occurs in Episode 24 during a mission to "The Boy Who Cried Wolf," where she overcomes self-doubt to lead the team. Equipped with tactical gear—a scouter and submachine gun—she coordinates strategies and confronts a Jyarei Monster, showcasing latent leadership and combat adaptability.

Her past briefly intertwines with fleeting connections: a bond with George, a "Cinderella" world clothing store worker, erased upon purifying the corrupted realm, and a mission in "Little Red Riding Hood" where she forms a transient kinship with the protagonist. Both arcs emphasize the impermanence of personal ties within their duty’s scope.

Aligned with Earth alongside Hols, Drago, and Pochiro, her elemental affiliation reinforces her grounding presence. Thematically linked to Summer and June, these traits anchor her within the zodiac’s structural lore. Her role merges strategic problem-solving with combat support, emphasizing versatility in team dynamics.

Later narratives challenge her emotional resilience as threats intensify, though her arc remains centered on group missions and interpersonal cohesion, adhering to the series’ ensemble focus without expanding into solo backstories or post-series developments.
