Knock... Knock... Knock...
Tyler's attention was jolted awake, his thoughts returning to normal as he stared at the door leading to the hallway. For a second, he had thought the knock came from within the library and almost lost it. That would have been scary... He wanted to ask the person who knocked to enter, but when he realized the state of the room, he quickly got up and walked to the door.
After resting for a while, he finally felt a lot better. His mental exhaustion had been alleviated by thoughts of his sister and mother. Even though he knew there was no longer any hope of returning to Earth—he had investigated it several times in the past and had never found a way back—he had also died on Earth before coming here, so his body was probably long gone.
Only heroes who were summoned here were generally able to return to Earth. He shook the depressing thoughts off as he opened the door to see the aged demon, Albert, standing there.
