In his school days, Kurumada Masami was deeply impressed by Motomiya Hiroshi's Otoko Ippiki Gaki Daishou, and that's what inspired him to become a mangaka. He submitted his first work to Weekly Shounen Jump when he was in the 3rd year of high school. The submission was rejected, however when he went to the company hoping to get an explanation, he got to know Inoue Koo and became his assistant. Later, at the age of 20, he officialy debuted with his manga Sukeban Arashi.
