Rose has long, wavy, blond hair and a perpetually bored expression. Rose wears a black suit with a thigh length black jacket. He also wears a white frilled shirt with frilled cuffs (or large cuffs) and high collar, which he commonly keeps untucked. When he was a captain, he kept his hair somewhat straighter with a small black ribbon tied near the end. He wore the standard Shinigami robes and a sleeveless captain's haori, but with a frilled collared shirt under it.

A seemingly foppish man with a disinterested air, Rose is one of the more laid-back members of the group. He is frequently seen tuning his guitar and chatting with Love rather than paying attention to what is going on around him. He's interested in music and often discusses whatever singles have recently come out, such as the then-latest Prince of Darkness album. He also enjoys reading manga, a pastime shared with Love and Lisa, although he becomes irritated if anyone spoils a storyline for him.

Despite the disinterested behavior he exhibits, he seems to care for his fellow Vizard; he smiles happily when he realizes that Hachi is happy to have met Orihime, due to the notable similarities regarding their healing abilities. He also states that "the family is growing", due to Ichigo and Orihime coming to stay with them, even claiming that the aforementioned humans' designated partner/counterpart, Hiyori and Hachi, were similarly happy. Rose seems to pay close attention to dramatic effect while in battle, as seen with his starting a speech on the human nature to band together against a common enemy and his attempt to dramatically rise from the rubble of a building he was hurled into.
