"We could try to infiltrate into the mansion of the Smakusa Family and try to find clues about this connection between them and the demons? There must be some document or other... or even people who would accept bribes. If we find something about this Patriarch, the Emperor wouldn't want to arrest him but rather execute him for treason." Matthew gave the idea when he saw that everyone was quiet.
As great as the danger was, the idea seemed workable to most people present.
The Smakusa Family lived a little way from Oukiwa, further south, beyond the greenish mountains. Their estate was more like a fortress than a mansion, and this construction stood at the foot of the colossal mountain ranges, which split the continent in two. Because of its sturdiness, size, and complexity, this fortress was nationally regarded as the second-best protected place in the entire Broteforge Empire, losing only to the Emperor's Palace.
