Demonic Knight

A demon, wishing to be a knight eventually has enough power to grant his wish. Now he doesn’t know what to do.

One day Soar the low class demon, was out soul harvesting. If he did not collect a soul everyday, he would be killed in cold blood. He gets distracted by a soul on a far away hill. Using his unique ability to fly, he put speeds the other demons and makes it to the soul.
The only problem is that when he landed, the ground beneath him caved in, revealing a deep cavern.
Using his sword he delayed his fall and absorbed the soul.
Contrary to what he thought would happen, he was transported to a new world, now what will he do?
