A Bug, You Say?

It all started the day an adventurer I'd never seen before walked into my store. I didn't know then, but the adventurers knew something that we, the people of this town didn't. This didn't bother the other people that lived in this town but to me, it was like having a song stuck in your head, being unable to forget, unable to just sit back and just let our predefined life drive us to death. In this story, I tell the reader about a weapon and armor merchant in the town of Bunseki, try to figure out the reason for existing. Will he find out the truth of his existence or be swallowed by the harsh reality of the world?
