Tsunoda, an anthropomorphic Thomson's gazelle employed in the accounting division of Carrier Man Trading Co., Ltd., sports fashionable attire that deliberately defies standard office dress codes. This sartorial rebellion underscores her knack for manipulating workplace hierarchies through calculated favoritism. Her strategy centers on ingratiating herself with superiors like Director Ton, deploying flattery to reduce her workload while cementing her position. Though aware of colleagues' disdain, she dismisses their judgments, prioritizing pragmatic self-preservation over peer approval.

Her personality blends overt cheerfulness with shrewd social maneuvering. Actively immersed in social media and dating pursuits, she persistently ropes coworkers like Retsuko and Fenneko into her ventures. Gradually, she proclaims herself the "Love Police," dispensing unsentimental critiques on romantic entanglements and spotlighting emotional blind spots—from Retsuko’s hesitancy to Fenneko’s detached cynicism.

During the Christmas special *We Wish You a Metal Christmas*, Tsunoda coaches Retsuko on crafting curated online aesthetics for popularity. Yet she betrays subtle approval when Retsuko abandons staged posts for genuine moments of unfiltered joy, revealing her duality: wielding superficiality for social gain while quietly valuing authentic contentment.

Her rapport with Retsuko transitions from mutual wariness to cautious camaraderie. Initially dismissive of Retsuko’s reserve, Tsunoda later rationalizes her manipulative tactics as a means to temper Ton’s harshness, shrugging off office gossip. This pragmatic candor fosters détente, with Tsunoda intermittently providing sharp, unsolicited advice on Retsuko’s personal and professional dilemmas.

Her social media fixation proves double-edged—a Christmas Eve date sours as she obsesses over crafting the perfect Instagram post, mirroring Retsuko’s parallel struggles and critiquing the obsession with online personas over tangible connections.

Interactions with Fenneko oscillate between rivalry and uneasy collaboration, marked by barbed exchanges and reluctant teamwork. As Tsunoda ascends office social ranks, her unapologetic confidence and blend of charismatic flair with strategic insight solidify her as a multifaceted operator navigating corporate dynamics.
