Misunderstanding 

After accepting Count Grant's 'invitation,' Vicente asked Nova to return to the Bain estate. 

He didn't know what was happening, but he didn't want to get his girlfriend into trouble that might require him to use his powers.

So, after agreeing to accompany the Grant family guards, he left Nova behind.

A few minutes later, he arrived at the Grant estate in the city's wealthiest area, where he soon saw one of the largest estates he had ever seen.

Although this was only a family with the title of Count, this house was as rich as some of the powers with Marquises and even Dukes of the Seidel Kingdom!

The family had many subordinates and people coming and going from their estate. At the same time, there were a considerable number of Mages around.
