As Weekly Shonen Jump gradually becomes more sexualized, the Japanese survey site Goo Ranking wondered which older titles defied the magazine's young demographics to get its readers hot and bothered. Naturally, it surveyed Shonen Jump readers to see which series they remembered most fondly. The survey was carried out from March 29 to 31 and collected results from 250 men, all in their 20s and 30s. While some of the answers are not commonly thought of as ecchi manga, they contained elements that turned at least some of their readers on.
