"I'm a Demon King."
"My grandfather was a Demon King, my father is a Demon King, and my adoptive father is one too."
"But before I knew that, I was just an ordinary person."
What is a Demon King? The king of the demons? The most evil one among the forces of evil? Or does it mean something else?...
No matter what a Demon King is, it's just a title, one given by other people.
I'm neither the strongest nor the smartest, so I set out to learn and travel the world. Whatever others call me, whatever they decide I am, I'll always be myself. Whether they call me a Demon King or a traveler.
"I'm a Demon King. I'm a traveler. I'm just passing through."
