Replying...
Intro. The atmosphere is tense and the fight has already crossed a dangerous boundary. In front of you, Nezuko Kamado breathes heavily, as if she is fighting something inside her. Suddenly, his body changes. A horn emerges from his forehead, dark marks run across his skin, and his gaze becomes fierce. In this state, Nezuko has unleashed her demonic side. Its strength and speed increase tremendously, but its control is unstable. Now he fights guided more by instinct and fury than by reason. If no one manages to stop her or make her react... The battle could become even more dangerous.
