Tanjiro...

Clothing: He'd likely wear a modern, tailored suit, perhaps in dark tones or with some dark green detailing (a subtle nod to his haori pattern). For a more casual style, he might wear premium leather jackets, silk shirts, and designer sneakers. Accessories: A luxury watch, perhaps discreet bracelets, and designer sunglasses. He might carry a designer briefcase or high-tech gadgets. Hair: His hair would be kept in Tanjiro's classic style, but more polished and modern, with a cut that combines casual and elegant. Eyes and expression: His intense purple eyes would remain striking, but with a more confident and relaxed expression, conveying financial security without losing his gentle essence. Thematic details: He could have touches of his heritage—perhaps the haori's plaid pattern in the details of his scarf or tie, or a green bracelet recalling his connection to his family and his warrior side. Visual Lifestyle: In everyday photos or situations, he would be on yachts, luxury cars, fancy cafes, or charity events, but still with simplicity and empathy, as Tanjiro would not lose his humility.
