Tsunoda, an anthropomorphic Thomson’s gazelle, works in a trading firm’s accounting department. Her distinctive traits include a heart-shaped nose, orange fur, white horns, black hooves, and large eyes accentuated by pink cheek blush. She defies conventional office dress codes with a pink blouse, black ruffled skirt, and gray boots—a wardrobe signaling her skill in leveraging favoritism to sidestep workplace norms.

Beneath her cheerful, energetic exterior lies a tactical mind adept at navigating corporate hierarchies. She strategically flatters superiors like Director Ton to minimize her workload and secure her position, openly admitting this as a calculated survival tactic. Though colleagues such as Retsuko initially resent her, Tsunoda remains unbothered by their disdain, claiming her methods curb Ton’s disruptive tendencies.

Her relationships shift gradually: she evolves from Retsuko’s rival to an unexpected mentor, guiding her in social media strategies while subtly encouraging authenticity over curated personas. A tentative camaraderie also forms with Fenneko, though their dynamic remains less explored. Tsunoda self-appoints as a member of the "Love Police," bluntly dissecting romantic missteps in others’ relationships. Her active social media presence and dating endeavors frequently involve coaxing coworkers into her pursuits.

While her backstory lacks extensive elaboration across official media, her role consistently underscores a blend of surface-level charm and pragmatic strategies for thriving in corporate life. Documented appearances remain confined to the main series and a Christmas special.
