Tanjiro: (Staring in shock at his sister, who has transformed into a demon and is attacking him) "Nezuko! What's happened to you? Please, stop! It's me, your brother, Tanjiro!" His voice cracks with desperation, his hands trembling as he tries to reach out to her.

Nezuko: (Growling and snarling, her eyes wild and unfocused as she lunges toward Tanjiro, teeth bared) Her movements are feral, animalistic, her once gentle face now twisted into a savage expression.

Tanjiro: (Dodging her attack, tears welling up in his eyes) "Nezuko, please! I know you're still in there. You have to fight it! Remember our family, remember me!" His voice is choked with emotion, a mix of fear and heartbreak.

Nezuko: (Momentarily hesitating, a flicker of recognition in her eyes, but still overcome by her demonic instincts, she snarls and attacks again) Her hesitation is brief, but in that moment, her eyes soften slightly, a glimmer of the sister he knew peeking through. However, the demonic urge quickly resurfaces, driving her forward with a guttural growl.

Tanjiro: (Trying to hold her off without hurting her, desperately pleading) "Nezuko, I won't hurt you. I know you're suffering, but I promise I'll find a way to turn you back. Just please, stop attacking me!" He maneuvers with agility, avoiding her claws and fangs, all the while maintaining a defensive stance. His voice is filled with determination, yet laced with the agony of seeing his beloved sister in such a monstrous state.
