The Infernal King was left inside the room all alone with his thoughts.
He just stood near the glass window, gazing outside. It was the world of the living... The realm where an undead like him shouldn't have been. Even the air of this place was disgusting to him.
Fortunately, he appeared to control himself well, despite being in a place that he hated. He didn't try to leave anymore. If all he needed to do was to spend the night in the room, then he was going to do it.
However, he did keep glancing back at the place where he had seen that Spectre before.
Not long after Gabriel left the room, the Infernal King felt another powerful aura getting closer. The aura was strange. It was filled with life, yet it was something that he could feel being quite powerful.
