In this world, where there is kindness, there will be evil, and where there is beauty, there will also be ugliness. Some people wear smiling masks, while others put on the cloak of hypocrisy. Devils walk in the world in human form, and their hearts are full of desire and evil. They stretch out their hands to kind people and point to the door behind them, saying that it leads to heaven. In this world, if there is evil, there will be justice, and if there is crime, there will be attacks. Some people use the law as weapons, wear moral armor, patrol the territory like a lion, and their hearts are filled with light and justice. They shoot at evil and end the devil. In a world illuminated by light, crimes cannot be concealed and evil has nowhere to hide. Police × Expert
