Hiyakawa X Mikado -

Their most famous operation, the "Night of Silent Ledgers," is a case study in their method. Hiyakawa discovered that the Balbadd Traders' Guild was planning to artificially inflate bread prices during a famine. He didn't try to stop them. Instead, he leaked the guild’s secret price-fixing documents to three rival criminal gangs at once, then had Mikado “rearrange” the lock on the guildmaster’s vault.

Their story is instructive because it redefines power. In a world of dungeon conquerors and Metal Vessels, Hiyakawa and Mikado had no magic. They had no king’s backing. What they had was a perfect, cynical division of labor. hiyakawa x mikado

In the sprawling, merchant-driven metropolis of Balbadd, two figures moved like shadows through its political twilight. They were Hiyakawa and Mikado, known collectively to the underworld as the "Hollow Duo." To understand them is to understand the desperation that festers in the gaps between kings and beggars.

And in every whispered deal and every toppled noble, the names Hiyakawa and Mikado remain forever intertwined. They had no king’s backing

When Mikado returns from a mission, she doesn't report. She just nods. Hiyakawa, in turn, ensures her favorite brand of bitter tea is always steeping in the cistern’s main chamber. Theirs is a language of shared scars and unspoken understanding. They are a reminder that in the brutal ecosystem of a fallen kingdom, the most dangerous thing isn't a monster from a labyrinth. It’s two people who have perfectly learned to cover each other’s blind spots.

Hiyakawa’s information network was his true weapon. He knew which guards took bribes, which alleyways the city watch avoided, and which noble kept a secret second family. His voice was rarely heard above a whisper, but when he spoke, empires of illicit trade shifted. He was the one who found the abandoned underground cistern that became their headquarters. He was the one who devised the "Toll of the Forgotten"—a tax on the corrupt merchants themselves, siphoned off through fake shipping manifests and ghost warehouses.
