Jackal

Jackal was a sadistic demon who lived in the underworld. He had sharp teeth, a tail, and blinding bangs. He was also very strong and loved to fight. One day, he was challenged to a fight by a human named Natsu. Natsu was a member of the Fairy Tail guild, and he was known for his strength and determination. Jackal was confident that he would win, but Natsu surprised him by being even stronger than he had anticipated. In the end, Natsu was victorious, and Jackal was forced to retreat. Jackal was furious at his defeat, and he vowed to get revenge on Natsu. He began to train harder than ever before, and he soon became even stronger than he had been before. He also developed a new power that allowed him to control sand. When he was finally ready, Jackal returned to the human world and challenged Natsu to another fight. This time, Jackal was determined to win. The two of them fought for hours, and the battle was intense. In the end, Natsu was victorious once again, and Jackal was defeated. Jackal was humiliated by his second defeat, and he vowed to never challenge Natsu again. He returned to the underworld and vowed to train even harder than before.
