After Defeating the first Demon King, Nichiro immediately goes on an adventure to the second Universe called MORTUUS. While on the way using Dance Liner Nichiro get a nuisance by a Waiter Train Dance Liner. The waiter bothered Nichiro who was relaxing while waiting to get to the second Universe. Nichiro who was relaxing arrived thrown goods that were in the car by the waiter. Nichiro who saw the incident can only be shocked because the object floated and headed towards him, and the severity of Nichiro almost hit by a kitchen knife in the train. The kitchen knife shot fiercely towards Nichiro and almost hit Nichiro's head. Nichiro could only tremble because of the incident. Not long after that the waiter raises himself in front of Nichiro. The waiter was wearing a black shirt with long hair and floated, the Waiter also had a slightly transparent body. Nichiro who is afraid of ghosts can only tremble and resignedly see the waiting figure. With a burning anger the Waiter threw the kitchen knife in the car very fast towards Nichiro. The ghost waiter thinks that Nichiro killed himself and the ghost wants to avenge him against the person who killed himself and his family. Behind the fast train turns out there is a tragic story behind it. The waiter named SHIRO, previously he had a happy little family namely Mother, Father, and his sister Shiro. Even so, the Shiro family is a family that is in short supply. That way Shiro must support all members of his family, because Shiro's father is 67 years old and can not work anymore. While Shiro's mother was 64 years old and her sister was 10 years old, Shiro himself was 17 years old. Therefore Shiro had to work anything to support his family. Many times he went home with injuries or came home bleeding. Shiro did not mind that as long as his family could eat and could provide for his small family. All that changes when Shiro and his family eat together, with their house suddenly broken down by an organization that likes to experiment with humans called "justice organization under government protection" or commonly called (J.O.U.G.P).
The name is simply the name of the lure of government that wants residents to believe that the organization is protecting them by impending danger. Shiro and Shiro's family are kidnapped and taken to J.O.U.G.P headquarters to experiment with a train called Liner. They were forced to dance inside the train as the train was traveling very fast. After speeding very fast the train is on the brake with brakes that have been made in such a way that the brake is strong when the brake is sudden. But it turns out that the trial failed and the shiro family immediately crashed and died in a very sad way. The shiro family died with limbs separated from the rest of the body which left the carriage covered in fresh red blood. Not until that organization took the Shiro family brain to be used as a new train machine and other organs in use to make rails, tires, and other organs, and technology that can respond to what is said. Shiro who is still alive and sees his family die with a terrible death can only be silent and resigned to what has happened to him and his family. Shiro died by mutilating his limbs and was left deprived of blood to death. Finally a sophisticated train that can explore the universe was born and the train was named DANCE LINER. But the train will reduce the lives of users of the train as much as the distance traveled to make it fuel from the train.
Nichiro who is still dealing with the ghost does not know what to do to get rid of the ghost. Shiro's ghost, knowing that Nichiro is not the killer, can only cry and mourn the fate that has befallen him. Nichiro is confused why the ghost is crying by accidentally asking why the ghost is crying. Hearing Nichiro's question, the ghost tells the story of why he could become a ghost like now. Nichiro who heard the ghost story felt sorry for the fate of the ghost. Nichiro advises that he does not take revenge against the person who killed him and his family because his revenge will only bring trouble to others who do not know anything. After a long time advising Shiro, Shiro finally realized his behavior that caused problems to Nichiro even almost claimed the life of Nichiro as well. Shiro who took his revenge turned him into a grain of light and disappeared. But Shiro came back with a different form he came back with a very beautiful girl with long hair. Shiro runs to Nichiro and hugs him tightly. Shiro is very grateful for the help of Nichiro he can return to being human again. Shiro promises to protect and follow Nichiro during his journey. Nichiro can only smile because Shiro is very beautiful like the girl whom Nichiro coveted. Shiro's stomach immediately felt hunger due to the change in form. Hearing that Nichiro immediately cooked food for Shiro. Nicki also cooks a lot of food for them to eat. Nichiro also told Shiro to eat as much as possible until he was full so as not to feel his pain anymore in the past. Shiro immediately ate the food that Nichiro cooked greedily and to the point of crying because he could taste good food. Nichiro finally finds his passion again, which is to keep and care for Shiro so that Shiro does not suffer anymore. Nichiro was happy because Shiro ate his food greedily. Nichiro gets a new skill Sacrifice of love where the skill can give protection to the person who wants to be protected and absorb every attack to be converted into strength but the skill causes a slight wound every attack absorbed. (The greater each attack received the more power received and the greater each attack received the greater the wound effect received).
..."The story ends with Nichiro and Shiro continuing their journey to a universe called Mortuus. But will the person whom Nichiro loves will be the same fate as the one whom Nichiro loved before??"....
