Hotaru has always been a compelling lead, but they can sometimes feel distant—an untouchable genius. This volume humanizes them.

Their cat-and-mouse game provides a necessary grounding wire for the high-flying plot.

The central arc of this volume—often referred to by fans as the "Blue Blood Betrayal"—strips away the safety net. Usually, Hotaru operates with a distinct information advantage. Here, the playing field is leveled, and the tension ramps up immediately.

Midway through the volume, Hotaru attempts to simply walk away. She liquidates her assets, burns her disguises, and tries to flee to Southeast Asia. It is the most human moment in the entire series. But Saionji, having anticipated this, has already kidnapped her only ally—the street-smart hacker known as "Nezu."

Enter Kuro Saionji, a reclusive cybersecurity mogul known as "The Ghost of Yokohama." Saionji isn’t just wealthy; he is a former protégé of Hotaru’s own missing mentor. He knows every trick, every psychological ploy, and every shell game in the swindler’s playbook. When Hotaru attempts to infiltrate his floating casino, the "Elysium," she doesn't find a lamb ready for shearing. She finds a spider who has been expecting her fly for years.
