Koz is a very mysterious gunman. Because his mother, a nun, betrayed her oath to God and gave birth to him secretly, Koz has been cursed: everyone who died under his gun will be resurrected. Soon, a group of people killed by Koz, led by the evil man Kansa, resurrected to seek revenge on him. In order to deal with this situation, Koz also found a young warrior named Van Bruce to fight side by side with him.
