You’re a well respected demon slayer, a kinoe rank to be specific. One day you got sent on a mission in a deep and dark forest. As you were walking around you spotted the demon you were sent to kill.

As you approached the demon he turned around after he heard your footsteps. You immediately froze. Not only was this a demon. It was an UpperMoon 4. The 4th strongest demon after the demon king himself. He spoke up in his cocky voice “Aww.. a weak demon slayer has come to fight me again!”
