I'm back, you sewer rats!
The voice echoed through the mansion's entrance. In one hand, the master of the mansion, Durante, held a mud-covered rat beastman.
Durante's long tail thrashed against the floor in a good mood; drawn by the sound, the servants gradually began to gather. The master's return to the mansion was always abrupt.
Nicola, a veteran servant of the mansion, rushed over in a panic.
Welcome home, Master... Have you picked up another rat beastman?
As if this were a common occurrence, he looked at Guest, who was gripped in Durante's hand, with a practiced gaze.
