"Boy, what is your name?", asks the stranger. After hearing this Kai opened his eyes, he was at the railway station. He was distraught and asked the stranger," Did you see my sister somewhere in the forest? She was being dragged by some creature which was beyond human!!" The stranger replied that he hadn't seen anything there except him on the ground, drenched in rainwater. The stranger said," Boy you will not find your sister with the police or the army, there is only one place you can go to acquire the power to see your sister." Kai asks where that place is.
The announcement came in the station:" The train going for Hokkaido is arriving on platform number 4. I repeated train no. E5579 going to Hokkaido from Tokyo is arriving on the 4th platform." The platform started to vibrate and the sudden horn of the train came. The train entered the station, stopped and the door opened in front of him. The man walked and got onto the train and declared," This is the train that decides your fate, whether it is to go home, to let your father search your sister, and let him keep on searching without getting her till his end. Or it is for you to find her by the strength that you will attain to fight those monsters." Kai ran to the train and entered it. The announcement came," Train no. E5579 to Hokkaido is leaving the Station for the platform." The scenery started to move and Kai left Tokyo behind. This is his new journey, a journey to rescue his sister that can only be done by him and no one else.
With the voice of the changing tracks and the horn, the train has covered a significant distance. Kai is simply lying in his cabin and The man went to check out the train. He was summing up all the incidents that led to this outcome. Someone opened the door and when he looked it was that strange man. He came and lay on his bed. The man said my name is Fukashiki Katasuke, a retired sorcerer of the ERFANGST. Katasuke asked," Why were you there in the forests and what is it that you truly want?" Katasuke replied," I was really near that day, almost going to infiltrate hell, I thought my sword would finally reach Hades' but I was completely wrong what made me wrong was his interference, one of the 15 Dominators. Hades is a devil who is the king of hell, the strongest of all the devils, when humanity was at its early stages he brought an epidemic to the Earth, a virus that would turn humans into ghasts. Ghasts are humans who have the power of the devils, but not completely, they need human blood to survive. And we can't allow innocent people to die due to this, therefore the ERFANGST organisation was created by a German called Ernfagst Erfieth, an organization to ultimately kill the the creator of Ghasts, Hades."
