The artwork style, even some of their character's funny and perverted facial expressions, felt pretty similar to each other. Both main protagonists of these 2 mangas are a powerful and famous delinquent. You can see the similarities between Eiji Asuma - Toru Egawa and Eikichi Onizuka - Ryuji Danma.
