Tsubone, a Komodo dragon office worker in Carrier Man Trading Co., Ltd.’s accounting department, sports grayish-green scales, a perpetually hunched posture, and sharp yellow eyes accentuated by red lipstick. Her professional wardrobe features a navy blue vest, matching skirt, white dress shirt, and glasses secured with a chain, while off-duty moments see her in a purple sweater and gray pants.

Condescending and overtly sexist, she systematically undermines female colleagues while currying favor with male coworkers. Her manipulation tactics center on delegating excessive tasks—particularly to junior employee Retsuko—through feigned kindness, followed by derisive mockery. A signature power play involves challenging subordinates to open her tightly sealed snack jars, relishing their futile attempts.

Tsubone shares decades of history with Ton, the department’s former director, recalling their early careers marked by reckless company fund expenditures. She remains staunchly loyal post his demotion, visiting him when others abstain. Resistant to procedural updates, she clings to outdated methods, deflecting criticism with defensiveness while exploiting junior staff to sidestep accountability.

Her entrenched adherence to traditional hierarchies and seniority-driven authority cements her role as a secondary antagonist, reflecting workplace systemic inequities and generational friction through interactions devoid of personal growth.
