No System. Heaven has light and darkness, and people have good and evil. What do I have? Nothing but a sword, and a sword-born body. I slay evil spirits and cut down those in the mortal world, all just to survive...
This is a story of growing stronger through thrilling battles. The protagonist isn't useless, but isn't invincible either. Without hardship, even a rainbow can't shine brightly. People prey on one another, and everyone has desires, usually for gain. How much do you desire?
