Sometimes referred to as Katsuragi You. Started in 1996 and still busy today (or at least until 2018). A fair amount of work to collect. Doujin Nhentai ImHentia
One of my favorites. Does great toddlercon and elementary. Also has a ton of buxom slutty teenagers. Master of group action and bukake. What doesn’t he do well? Hitomi, Exhentai
