Sato got down from the carrige, right in front of him was Vlad's mansion with lots of maids lined up at the entrance.

"Master, it looks like the Duke was already expecting you." Yuri commented, walking out of the carriage and standing beside Sato.

Sato responded, "Seems like it, Let's go." Before he continued his advance toward the entrance of the door. 

Ignoring the maids, Sato and Yuri strolled inside the building, and as soon as they got inside, they were immediately met by Sebastian.

Sato arrived at the grand hall of the Nervek Castle, a massive structure made of white stone and adorned with intricate carvings. The hall was just as impressive, with high ceilings and elegant chandeliers hanging from above.

As Sato entered, Sebastian greeted him with a bow. "We've been expecting you, Lord Sato," he said, his voice echoing in the spacious hall.
