There was the boy named Tomas who lived in the town named Chygle with his parents. The people were massacred by devils who appeared in the world suddenly, and the world population largely decreased. And his parents were murdered cruelly in front of him by the devil. Then the angel appeared before some people who survived with him after devils left The angel told “This musical instrument is a weapon destroying the devil by your spiritual strength as a source of the power” and granted a special musical instrument to people and returned to the sky. And he was given a sax from an angel. When he buried his parents, devils appeared there. He was going to attack devils, but he remembered words said to an angel and controlled a feeling and blew on a sax. The sax played a requiem and devils did not get a motion. And when requiem was finished, devils became a particle and became extinct. People who were given a musical instrument to to an angel in all parts of the world have begun to fight against devils. The man named Anthology who was granted a musical instrument to first by an angel was given a trombone from an angel established an association named the association of the exorcist and gathered exorcists who were in all parts of the world. Exorcists who visited the association of the exorcist established the branch office of the association in each place. And when Tomas goes to the branch office of the association of the exorcist established in Chygle, there were many people there. The branch master named Ian of the association let he and three of men and women in gathered people make a team. Two men and women are a boy named Logan who was given a flute from an angel, and a girl named Nancy who was given a harp from an angel. And the people who were gathered in the association of the exorcist which included them were dispatched to each place to destroy the devil. The team of Tomas and Logan and Nancy went to the area where the appearance of the devil was reported in. When they played a musical instrument that they arrived and destroyed devils, exorcists confronted the army of the devil in the suburban town named Gresbiel. They arrived at the place where the appearance of the devil was reported in, and they played a musical instrument and destroyed devils. When exorcists finished playing a musical instrument at that time in Gresbiel, devils became extinct. And exorcists thought that they were able to destroy all the devils and was pleased, then two devils appeared from the underground and the sky. The devil who appeared from the underground threw exorcists the flames of hell, then the body of exorcists was wrapped in flame. The devil who appeared from the sky flew up in the sky and scattered an acid liquid, then the body of exorcists melted. When Tomas and Logan and Nancy happen to pass by Gresbiel, the dead body of exorcists of the horrible figure lay there. And they surrounded devils, and they played requiem with a musical instrument while avoiding the attack of devils, then the tone of their musical instrument played harmony and restricted the body of devils. The body of devils became a particle and became extinct. They came back to the branch office, after having buried the dead body of exorcists. And they went to various areas by instructions of association of exorcist and fought against devils.
