Backstory: Zeru Nakamura was born into a family of information brokers that have knowledge about the supernatural for generations. At the age of ten everything in his life changed, The Old Maou-faction appeared at his home. He was then safely stored away as his parents went to confront them. By the time everything went quiet, he looked to see the traumatizing sight of seeing the bodies of his now deceased parents. Later he wandered somewhere in Japan and collapsed out of exhaustion. He was then taken into an orphanage. About a mont later, he was adopted by the Hyoudou family, who wanted a second child but due to some complications in the past they weren't able to have one. Since then he had a normal life once again. But later on he meets Hephaestus the God of Blacksmith, who was an acquaintance of his family for generations. Since then he has been doing errands for Hephaestus such as looking for materials and other tasks. Zeru then wanted to follow in his family footsteps, so he decides to become a freelance information breaker. During his time in middle school he joined up a guild that apparently his parents were apart of called the Azure Fang.

Kind of feeling nervous, since this is my first time doing a challenge fic. Hopefully I'll do okay. I'll try to make sure to work on this, since I have my two other fics to work with.
