After the hero defeated the demon king, the world became peaceful--but it hadn't ended. After humanity's 'enemy' disappeared, from the era of 'violence' can the era of 'money'. At the nook of trade city Faltram, the wandering hero who had hidden his identity came across the demi-human Yunis, and the female knight, Rachel with whom she was discussing with.
