Donut time

Boe, Aman's loyal servant, stood before Rengoku, his eyes gleaming with malice. He had been sent to defeat the demon slayer and bring him back to Aman as a prize. Boe was confident in his abilities - he had never been defeated before, and he had no doubt that he could take down Rengoku with ease.

Rengoku, for his part, stood tall and proud, his flames burning brightly. He knew that this would be a tough fight, but he was determined to protect the innocent and defeat the demons.

The battle began, with Boe unleashing a series of shock wave attacks that Rengoku deftly dodged. Rengoku retaliated with his flame manipulation, but Boe was too quick, dodging and weaving through the flames with ease.

Boe then focused on using his ability to track Rengoku's bloodlust to his advantage. He began to close in on Rengoku, launching powerful shock waves at him that he struggled to avoid. Rengoku fought back with everything he had, unleashing his most powerful flame attacks, but it was no use. Boe was simply too fast and too skilled.

As the fight wore on, Rengoku began to tire. His flames flickered and dimmed, and he struggled to keep up with Boe's relentless attacks. And then, in a moment of carelessness, Rengoku made a fatal mistake. He left himself open for just a moment, and Boe seized the opportunity.

With a swift movement, Boe launched a powerful shock wave attack that struck Rengoku directly in the chest. Rengoku felt his body go limp, and he knew that he had been defeated. He fell to the ground, his flames flickering out, and Boe stood over him, triumphant.

Aman's servant looked down at Rengoku's defeated form, his eyes filled with triumph. He had done it - he had defeated one of the strongest demon slayers in the land. He could already imagine the praise he would receive from Aman, the rewards he would be given.

But then, something unexpected happened. Rengoku's body began to glow with a bright, golden light. Boe stepped back in surprise, unsure of what was happening. And then, in a flash of light, Rengoku was transformed into a donut.

Boe stared in disbelief, unsure of what had just happened. He had never seen anything like this before. But then, he heard a voice behind him - the voice of another demon slayer, who had been watching the fight from the sidelines.

"Looks like you underestimated Rengoku," the demon slayer said, a note of amusement in his voice. "He may be a donut now, but he's still a demon slayer. And you, Boe, are no match for him."

Boe snarled in frustration, but he knew that the demon slayer was right. He had been defeated, and he had no choice but to retreat. As he disappeared into the shadows, he could hear the demon slayer laughing behind him.

But Boe was not defeated for long. He would return, stronger and more determined than ever. And he would make sure that the next time he faced a demon slayer, he would emerge victorious.
