I Have No Regrets, I Have No Forgiveness for My Sins

More than five hundred years ago, many monsters suddenly appeared in the western part of the continent. These monsters all have two things in common. One is that they all feel resentful towards humans, and the other is that they all have human characteristics! After five hundred years of evolution, these monsters merged with the characteristics of many other animals, and their looks became increasingly weird. People gave this monster the name "Frenzy".

During a wild invasion, Lance fled the village with his friends, committing an unforgivable crime in the process. In the days to come, can mankind defeat madness? Can Lance successfully atone for his sins? All the answers lie in the novel.
