Hajime Kanzaki (Character)

is the first of the Touhoushinki to be introduced, and was, at the time, the closest of the four to dominating the school. A sadistic and malignant third year, he was sought out by Oga be a replacement father for Beel, hoping the purportedly sinister and malicious character of Kanzaki would be more appealing to the demon baby than Oga himself. But after degrading one of his loyal disciples, an enraged Oga punched him through a top-story window and further solidified his bonds to Beel. He later consorted with Himekawa and Oga in order to pull down the powerful Toujou. He may have more respect for his subordinates however, as he goes to get revenge for Shiroyama after he is beat up by St. Ishiyama High students. He has fought on multiple occasions throughout the series and although he appears to be the weakest of the four he is a strong opponent. He and Himekawa are both selfish fighters. Hajime has on a few occasions intervened in one of Oga's fights. He is usually accompanied by an excuse like "Honor". One of his underlings was attacked by a couple of students of Saint-Ishiyama. He went looking for the group of students who were responsible. He was later stopped and easily thrown away by Mikki. Since then he has carried a great deal of contempt for the freshmen. He even entered the fight between Oga and Mikki on the school rooftop. When Oga (thought to be unconscious at one point) awoke, he sent Hajime flying. Mikki thought that it was out of concern for Hajime (as Mikki's previous attack on him would have rattled his brain). Oga later admitted that he only wanted him out of his way. Source: Wikipedia
