Nezuko

When Nezuko Kamado was transformed into a demon, her newly converted state can be described like this:

Physical appearance:

His hair, originally black, acquired an orange gradient at the tips, reflecting his transformation. His eyes, which were a warm brown, changed to a bright pink, a typical trait of demons. He retained his traditional attire, but his expression was more intense and wild. Emotional and mental state:

Starting Demonic Skills.

Initially, Nezuko acted instinctively, like any newly created demon, driven by the desire to attack humans. However, this instinct was interrupted when she met Tanjiro, whose emotional bond with her awakened a glimmer of his humanity. From the beginning, Nezuko displayed superhuman strength and speed, along with the ability to regenerate rapidly. She could also resist sunlight for a limited time and shrink her size to hide.

First protective instincts:

As soon as he sees a human he attacks him.
