Swamp Demon

The Swamp Demon was a hot-headed demon with no eyebrows and purple hair. He lived in a swamp and loved to play pranks on people. One day, he was playing a prank on a group of humans when he accidentally killed them. He was so scared that he ran away and hid in the swamp. The Swamp Demon was eventually found by Tanjiro and Nezuko Kamado, two demon slayers. They fought the Swamp Demon and eventually defeated him. The Swamp Demon was then turned into a human again. He was grateful to Tanjiro and Nezuko for saving his life, and he vowed to never hurt anyone again.
