everyone lives with different races that rarely appear. However, these differences cause problems and hatred. So a creature called a devil appeared, this creature appeared because of hatred. The more someone hates something, the stronger the devil will be. Devils can also regenerate by drinking blood, whether it is animal or human blood. Because this made the city's residents restless, the government established an organization tasked with protecting the city from the threat of devils. The organization can be called the Regional Security Organization. The organization is tasked with patrolling every day with the number of members of the organization around 60 members. Most of them only do light patrols and extermination. It is quite rare for people to register or be recruited into this organization because of its extreme duties. Kiruna as the leader of the organization certainly chose a wise path, she visited every place to look for suitable and reliable recruits.
