Justice is Blind |『 Female OC 』• Kimetsu no Yaiba

Act 45: The Dawn of Hope

Tanjiro gritted his teeth, every muscle in his body screaming in protest as he drove his blade deeper, pinning Muzan to the wall. Blood trickled from his forehead, mingling with sweat as he groaned, putting everything he had into keeping Muzan immobilised. 'I won't...let go,' he thought.

Nearby, Ayuna shuddered violently, her body convulsing as Muzan's blood rampaged through her cells. Her vision blurred, black spots dancing at the edges of her sight. Her knees buckled, threatening to give out beneath her.

But even as her body betrayed her, her resolve remained unshaken. With trembling hands, she drove her three swords into Muzan's regenerating flesh, anchoring him further. "You're not going anywhere!" Ayuna snarled, her voice raw and defiant as blood trickled from the corners of her mouth.

Her trembling form leaned heavily against her swords as she tightened her grip with what strength she had left. Her breathing came in shallow gasps, her regeneration barely keeping her alive.

Muzan's monstrous form twisted, his tendrils coiling and snapping like wild beasts. His crimson eyes narrowed, locking onto the two slayers as malice radiated from him. His left whip lashed out with a snarl, aiming to crush them both.

*Snap*

But before it could reach its mark, the whip was halted mid-strike as an injured Mitsuri grasped it with both hands, her muscles straining against the attack. "Cut it out already!" Mitsuri shouted, her voice trembling with exhaustion but filled with unyielding determination.

Her vibrant pink and green hair was matted with blood and dust, but her eyes still shone with defiance. She yanked hard on the whip with a fierce tug, forcing it away from Tanjiro and Ayuna.

But the victory was short-lived. Muzan's right whip snapped toward her like a viper, striking her across the chest and sending her flying back with a pained scream. "Kanroji-san!" Tanjiro cried, his heart clenching as he watched her crumple to the ground.

*Whoosh*

A flash of steel sliced through the air, severing Muzan's right whip. Sanemi emerged from the dust and launched himself toward Muzan with a feral snarl. "You're not the only one who can bite!" he roared, cutting through Muzan's appendages with Wind Breathing.

Muzan hissed, his crimson eyes burning with fury. His monstrous mouth opened wide, splitting his torso all the way to the top of his head. Rows of jagged fangs glistened as he lunged forward, his maw descending on Tanjiro and Ayuna.

The world seemed to slow around them. Tanjiro gritted his teeth, his knuckles white as he gripped his blade tighter. 'Don't retreat. Don't step back!' he told himself, his mind a storm of fear and resolve.

Beside him, Ayuna's thoughts mirrored his resolve. She was still trembling from her convulsions, forcing her body upright. 'Whatever happens to me doesn't matter as long as you are done for!' she thought.

But another shadow surged forward before Muzan's gaping maw could close around them. Obanai appeared, his body a blur as he positioned himself between Muzan and the two slayers. With a fluid motion, he raised his blade.
