Yamauchi is a young man of below average height who has brown hair with red eyes. He is often seen wearing the standard school uniform.
According to his interviewer at the entrance examinations, he has a tendency to lie.
Like some of his friends, Haruki has a perverted side and is attracted to Kikyō Kushida, as he was willing to participate in trying to peep on the girls. He also shows an attraction to Airi Sakura both for her well-endowed body and for her sweet nature, which appeals to him.
In the survival test, while he was picking up branches, he told Kiyotaka Ayanokōji that, he was going after Sakura, because of Kikyō Kushida, being out of his league, and claims that Sakura will fall for him if he starts acting like a nice person.
