On the end of a day of work; after finishing a test play, Haruto decided to head home via the train. While on the train, Haruto started to feel tired and sleepy. After some time He feel asleep. He woke up to an amazing wide landscape. He must be dreaming he thought. He saw that there was a interface just like in ToF. He could feel, hear, smell. It was like he was in an VR. He thought that everything was fun until a large orc came up to him and showed him that what he though was a ream may actually be reality.
