Toshio Maeda is a legendary author of hentai manga from the 80s and 90s, known worldwide as the “Tentacle Master” for his popularization of the use of tentacles as erotic devices. Born and raised in Osaka, Japan, Maeda moved to Tokyo at only 16 years old to pursue life as a professional manga artist. His most notable works include La Blue Girl, Demon Beast Invasion, Adventure Kid, Demon Warrior Koji, and most infamously, Urotsukidōji (Legend of the Overfiend), which produced several Original Video Animations (OVAs).
