Why fight a war when you can buy the kingdom?

Transported to a primitive medieval realm, three genius brothers realise that swords and armour are useless. Instead, they unleash the most terrifying forces known to man: steam engines, modern medicine, and fiat economics.

Under the banner of the Kazuha Syndicate, they orchestrate a ruthless industrial revolution that shatters the old world order. Knights fall to bullets. Monarchies are bought with paper money. But when neighbouring empires mobilise millions to steal their technology, the Syndicate must wage an industrialised world war to protect their new empire.

Three minds. No magic. Total domination.

Those who adapt, rule. Those who cling to the past, perish.
