Rin has messy, jet-black hair (dark blue in the anime) that sweeps down in his eyes, pale skin, and intense blue eyes. While in his human form, Rin exhibits a number of physical traits that hint at his Demonic nature, such as prominent canine teeth and slightly pointed ears. After using Kurikara for the first time, Rin also gains a black, fur-tufted tail that he usually keeps hidden under his shirt.
As a Demon, Rin gains two, horn-like blue flames floating above his head, long elf-like ears, and slitlike red pupils while his irises remain a deep blue. The blue flames also blaze around other places of his body, mostly at the tip of his tail.
