Welcome to “Kind Heart”. To a city famous for its serial killer, nicknamed “The Thief of Hearts.” To residents who are accustomed to murders every three days. To the city where the main monster works as a policeman, and where everything is covered in darkness. How could a place like this get any worse? It turns out yes! It all starts when serial killer number two appears in the city. A monster that eats its victims. A huge werewolf, under the cover of the all-seeing moon. When all the newspapers start writing only about the new killer, forgetting about the “Heart Stealer”, and a new war begins. The war is not between evil and good, it is another war. And few people will like its outcome. When evil fights on both fronts, you have to become a monster.
