Appearance
Haruki is a young man of average height with short brown hair and red eyes.

He is often seen wearing the standard school uniform.

Personality
According to the interviewer who assessed him during the entrance examination, Haruki has a tendency to lie.

Similar to his friends, Haruki has a perverted side who is attracted to Kikyō Kushida as he was willing to peep on the girls. He is also very attracted to Airi Sakura and Haruka Hasebe, mainly for their well-endowed bodies and quiet nature.

During the island test, while he was picking up branches, he told Kiyotaka Ayanokōji that, he was going after Airi, because of Kikyō being out of his league, and claimed that Airi would fall for him if he began behaving nicely.

Despite his negative traits, he was, although rarely, able to act maturely as shown after being rejected in volume 4.5.
