High School DxD is a Japanese Anime series about coed Catholic school students, who against all adversity, struggle to repress their inherent desires of sexuality. Throughout the school year, they are consistently harassed and by devils and fallen angels. Often times these antagonists appear before them and tempt them with needlessly scanty outfits and outrageously large bazongas. However, the characters never stray from the path of salvation by keeping true to their faith in God. The series follows the members of the occult research club, a group of particularly pious students who seek to weed out devils among the student body disguised as students with DD breasts.
