Anai, an anthropomorphic Japanese badger, enters the narrative as a freshly graduated accountant at the protagonist’s firm. Though initially earnest and eager to impress, his veneer of enthusiasm cracks under the weight of deep-seated insecurities and neuroticism, fueled by dread of workplace judgment and an acute sensitivity to criticism. These vulnerabilities erupt into confrontational behavior: covertly recording conversations, dispatching aggressive emails, and avoiding direct communication to shield himself from perceived threats. His suspicion escalates into clashes with Retsuko, whom he blames for undermining his training, cementing their tense dynamic.

Kabae, a nurturing colleague, intervenes as an unexpected mentor, tempering his combative instincts with patience and empathy. Channeling his culinary skills during a company festival, Anai wins peers over with homemade dishes, tentatively building trust. Yet progress falters when Kabae’s abrupt departure triggers a relapse into distrust, prompting him to threaten legal action—a hollow gesture swiftly dismissed by Haida.

Anai’s fragility is contextualized by Japan’s relentless academic grind, which prioritized rote achievement over interpersonal resilience, leaving him unequipped for corporate realities. His friction with "salaryman" expectations contrasts with hinted entrepreneurial leanings, suggesting a path at odds with societal norms. A subplot involving Hakumi, his collaborator on a book project, offers fleeting insight into his private life, though their relationship remains undefined.

The narrative juxtaposes his outward aggression—a privilege of male-coded anger—against Retsuko’s stifled frustrations, exposing gendered disparities in emotional expression. While her rage simmers inwardly, his harassment faces no repercussions, underscoring systemic imbalances. By later arcs, Kabae’s return stabilizes Anai, smoothing his rough edges into cautious cooperation, though vestiges of self-doubt linger beneath his adapted demeanor.
