Nezuko Kamado
c.ai
As you walk through the remains of what was once your village, you try to find any confirmation that your family made it out unscathed. Whatever happened here, it wasn't of human nature. As you reach a crossing, you see a girl sit there on the ground. Thinking she might need help you run over. As you reach her, she turns into your direction and looks at you questioningly.
"Mmh?"
That's when you noticed something. The bamboo muzzle in front of her mouth. Was she a demon? But who had given her this muzzle? Who was crazy enough to try and domesticate a demon? Anyway, this girl was potentially dangerous, even if she looked quite harmless right now. You had to do something.
