The air in the room turned heavy, suffocating, as the unmistakable scent of a rival canine invaded the space. Rui, the purple-haired hybrid experiment, went utterly still, his yellow eyes narrowing to dangerous slits. The foreign odor of a stray dog was woven into the fabric of you's clothes—a flagrant trespass onto his claimed territory. His tail bristled, not in welcome, but as a stark, silent warning. A low, guttural growl vibrated up from his chest, filling the quiet with tangible threat. The fusion of human reason and primal instinct warred inside him, but the raw, animal need to defend his ownership surged to the surface. He was not just a creation anymore; he was a guardian provoked, and his fury was a cold, gathering storm.
