Summary: Y/N, a demon slayer, is determined to take down Kokushibo, one of the Twelve Kizuki. But when Kokushibo saves her life during battle, Y/N begins to see the demon in a different light. As they spend more time together, Y/N and Kokushibo start to develop feelings for each other, but their love is forbidden by their respective roles. In the end, they must choose between their duty and their hearts.
Y/N had always known that her life as a demon slayer was fraught with danger. But she had never felt as alive as she did when she was on the battlefield, fighting against the creatures that threatened humanity.
Her latest mission was to take down Kokushibo, one of the Twelve Kizuki. Y/N had trained long and hard for this moment, and she was determined to succeed.
But things did not go according to plan.
Kokushibo was a formidable opponent, with skills that far surpassed any demon Y/N had ever faced. Their battle was fierce, with both combatants giving their all.
At one point, Y/N found herself in a vulnerable position, with Kokushibo poised to strike the final blow. But to her surprise, the demon hesitated, his eyes flickering with something that looked like regret.
In that moment, Y/N saw Kokushibo not as a monster, but as a being with his own fears and doubts.
Their battle ended in a stalemate, with both Y/N and Kokushibo gravely wounded. As Y/N lay dying, Kokushibo approached her, a look of concern on his face.
"I can save you," he said, holding out his hand.
Y/N hesitated. She knew that accepting help from a demon was against her duty as a demon slayer. But she also knew that she didn't want to die.
In the end, she took Kokushibo's hand, and he used his powers to heal her wounds.
As they traveled together, Y/N began to see Kokushibo in a different light. He was no longer just a demon to be defeated, but a complex being with his own hopes and dreams.
And as they spent more time together, Y/N found herself falling in love with Kokushibo, despite the impossibility of their union.
Kokushibo, too, felt a connection with Y/N that he had never experienced before. He knew that their love was forbidden, but he couldn't help his feelings.
But duty called, and Y/N and Kokushibo were forced to part ways. They both knew that their next encounter might be their last.
As they stood facing each other, Y/N and Kokushibo shared unspoken regrets. Regrets for the paths they had chosen, for the roles they were born into.
But as they prepared to do battle once again, they both knew that their love, no matter how forbidden, would always linger in their hearts
