Vocalist and the younger member of the idol group ŹOOĻ. He attends the same school as Iori and Tamaki. He likes sweet things and always eats special doughnuts made by a young girl, despite thinking they are not good. He was a straightforward child who worked hard toward his goal, but he was distorted by a certain incident. Haruka is said to harbor a deep hatred for Tenn and Kujou Takamasa. Desperate for revenge, he accepted Tsukumo Ryou's offer to join Tsukumo Productions and form the idol unit ŹOOĻ.
