Iko’s natural hair color is white, matching the rest of her fur. She’s not largely accepted among fellow kitsune due to the curse mark on her forehead. Many avoid her like the plague as it’s a clear indication that she was marked for death by not just the gods but by Inari, the god that watches over all vulpine kin. In short she was cursed by the very god that created her. I’ll answer in more length if anyone cares to ask why.
