The Only Aura User In Magic World

Tonight is the time for us to face the Vampire King and see what his intention in approaching Cassau.

"There were no other vampires other than you guys before, right?" I asked Arin and the other vampires who are preparing to go.

"No. And you should know it best. They are hiding in a mountain quite far from the lake where I found their trace. When I saw them before, they were building a castle," Arin said.

"Do vampires need castle? Want me to ask Albert to build one for you guys?" I asked Arin.

"No need to do that. I'm satisfied with what I have. And having a castle is just a pain in the ass to clean regularly," she said.

No wonder she never asked me to build her a castle. I guess she experienced it from back then when I found her in the castle.

Though she can use Charm magic, right? I guess she just charmed the male vampires to clean the castle. While the female vampires didn't do anything.
