"I want to make the cube take us to the other demon." The half-dragon request was still echoing in Luke's head, who was not bold enough to give an answer on the spot.
To follow and find out where the cube would take them, they needed to be prepared for another encounter with a demon and, at worst, the escape of the demon trapped in the cube.

However, the man was not only worried about himself but also about Nathalia. Although he was completely sure that she would be able to give Alexis and him good support in a battle, he felt that the girl had no such confidence yet.
