**Height:** 175 cm (5′9″) Haruki is described as sharp and somewhat rambunctious. He's also incredibly ambitious, putting his all into every piece of work he contributes to and keeping a tight focus on his work, to the point where he's forced to take breaks if found out. Despite his outgoing personality, he still has trouble talking to his crush, and is very similar to her in that they both don't have the courage to confess to one another. When it comes to something he likes, he's said to be constantly criticizing it instead of praising it because he finds it fascinating, in what Yu calls a tsundere fashion. His criticism of Miou's work also stems from that aside from the obvious assistance.
