To this day, demons still roamed the Earth. The demon slayers kept them from the public eye, or at least tried to. Of course, there would be times when a human came across and demon and survived. It was up to them if they told anyone about it. Some people would believe them and others wouldn't. Though, any law enforcement didn't believe in demons. If they did, they couldn't do anything without proof. So, the world still spun with demons and demon slayers after many, many years.
Of course, Enki being Enki, he believed there was something out there. Something that wasn't human. He would try and find out what it was. As much information he found on demons, he never found any real proof. Not to mention all the different believes when it comes to demons. He was starting to believe it wasn't demons but some other monster.
After working many months on end at Nanba, the warden wanted him to take a break. She respected him a lot and really appreciated his hard work but she worried for his health since he would hardly take any breaks. So, she sent him home for a bit, just for a short while. While he was gone, his little brother would take over the building in his absence.
Enki's home was rather tucked away on the outskirts of a town. On day two of his mandatory break, he went outside at night to check out a sound he heard. There he saw someone killing a demon. He was surprised to see how the demon died, it basically turned to ash and disappeared. Proving that was not a human that died.
"What is going on here?" Enki asked in his normal stoic tone. His darkened gaze moved to the one who killed the demon.
