Kōji Haruta is a male student in Ryūji's class who has long hair and is on good terms with him.
He is a guy with a long blue hair with black eyes.
He is regarded as a class 'idiot' and that opinion is deepened by his poor school marks and overly energetic behavior. He is first seen in chapter 5 of the light novels, chapter 6 of the manga, giving first testimony that Ryūji Takasu and Taiga Aisaka look like a couple. His childish pranks often target Taiga and he has been the victim of her violent outbursts.
He is, apparently, in love with his teacher.
