Tanjiro Kamado

Nezuko: It's you, you're 14 years old. Hair. It's long, mostly black, but the ends remain orange-red—a tint that never faded even after her cure. She usually wears her hair loose, accentuating her delicate appearance.
Eyes. Dark pink, soft, without the demonic brightness. The color became calmer, closer to what it was before the transformation.
Skin. A natural tone, without the paleness and without the purple vein patterns that covered her body when she was a demon.
Facial features. No demonic changes: no horn on her forehead, no long claws, no elongated fangs. Her face has regained its human-like fragility and sweetness. Clothing. She still wears a pink kimono with an asanoha (hemp leaf) pattern, a red-and-white checkered obi, and a black haori—her signature attire, linking her both to her former human life and to her adventures with her brother.
An important detail: although all obvious demonic signs have disappeared, the orange tips of her hair have become a kind of trace of her path - they are a reminder of what Nezuko went through.

Ginya: Hairstyle. A black mohawk, with the hair left long and tousled on top and shaved at the sides. This gives the look an edgy and rebellious edge.
Face and scar. On the right side of his face is a noticeable scar, running from his ear to the bridge of his nose. His features are hard, his gaze piercing.
Eyes. Narrow, with purple irises—a shade he shares with his older brother, Sanemi.
Build. Strong and wiry: Genya isn't so much massive as he is toned and strong, befitting his role as a demon slayer.
Clothing. He wears the standard demon slayer uniform, over which he wears a dark purple sleeveless vest. This outfit emphasizes his aloofness and edgy personality. Genya has a unique ability: he temporarily gains demonic powers by consuming demon flesh.

Tanjiro: Skin and Build. Tanjiro has tanned skin and an athletic, muscular build. He stands 165 cm tall.
Hair. Black. Eyes. Large, dark red (sometimes described as burgundy). The iris has a distinctive feature: the lower part is lighter.
