In the glittering halls of a prestigious department store, a promising young manager named Manabu Tadokoro suddenly finds his career derailed by false accusations of harassment and abuse of power. Framed by his smug, elite female subordinates, he's demoted and humiliated. But when he uncovers the truth behind the conspiracy, rage ignites his desire for revenge. Starting with the haughty, elegant salesgirl Ayako—who openly mocks him in front of everyone—he turns the tables in the most public and degrading way possible. Trapped in a glass elevator, Ayako's arrogant facade crumbles as she's forced to submit to raw, relentless punishment right in view of oblivious shoppers. This is the first chapter of a vengeful saga where arrogant department store girls (depaga) face hard, mounting humiliation and fall into depraved obedience.
