Appearance

Personality
Cold and analytical, Haruki has shown to have some sort of detestation towards esper abilities to the point where he will showed that, for want of a nail, Kongou Mitsuko could've made the situation worse with her using her powers against a robber, even though the situation has already satisfactorily resolved. He has shown enough charisma to convince a crowd, who was awed at first by Mitsuko, that his arguments are correct.

He is often shown adjusting his glasses with his middle finger.

Silent Party Arc

 * Main article:Silent Party Arc

He has ITEM hired in an experiment to test out their Powered Suits. The experiment proceed smoothly despite the team destroying all the Powered Suits, though making Mugino Shizuri bleed a bit. However, something unexpected happens and the warehouse where the experiment is being held goes into flames. Despite this, he is confident that it will sort it out soon.

He is later seen in broad daylight wearing his uniform. After witnessing Kongou Mitsuko stop a purse snatcher using her powers, he arrives to admonish her for using her powers, making an appeal to probability fallacy to support his claims, convincing the bystanders who were previously impressed by Mitsuko and making her feel bad. Wannai Kinuho and Awatsuki Maaya arrive after finishing their errand of summoning Anti-Skill to collect the snatcher, but Haruki simply gives out a smug smile and quickly leaves before they can make a case against him.

He is later seen again with a meeting with his fellow STUDY members, telling them that despite the unexpected event that had happened during the experiment, he is confident that it will sort itself out soon. He states that all preparations have now been completed, and that it is now time to show the city that is obsessed with espers their power. He asks to make a vote if they wish to proceed to the next step, and all of their members raise their hands in agreement.
