Aoba Hashibira is the great-grandson of Inosuke Hashibira and Aoi Kanzaki. He is a well known botanist involved in researching the Blue Spider Lily. Aoba shares a striking resemblance with his ancestor, with both having feminine features that cause people to mistake him for a woman. He has black, shoulder length hair with overlapping bangs and emerald green eyes. However, unlike Inosuke, Aoba has a physically smaller build and jet black hair rather than hair that fades from black to blue like Inosuke's, the same as Aoi. As a researcher, he wears a standard uniform consisting of a white button up shirt and lab coat, as well as blue slacks and black shoes. Unlike his ancestor, Aoba has a timid personality and is incredibly intelligent. Being the botanist in charge of researching the Blue Spider Lily, he held a press conference to apologize to the public for a mistake in their research. Despite the stark contrast, Aoba has shown a similarity to Inosuke. Following the mistake in his research, Aoba had voiced his wish to "live alone deep in the mountains."
