Doukyuusei is a series of adult dating sims by ELF Corporation. The original Doukyuusei released in 1992 for the NEC PC-9801 and is generally considered by many to be the first dating simulation. It was followed up with the sequels Doukyuusei 2 and Kakyuusei, both of which were also very successful. In 1996 production on an adaptation of Doukyuusei 2 began overseen by KSS (Also produced Golden Boy, Idol Project, and Variable Geo). Character Designs were handled by Rin Sin (Character Designer for all anime productions of Queen’s Blade and Ikkitousen) 12 episodes were released over the next 2 years. A sequel in 1999 titled Doukyuusei 2 Special: Sotsugyousei consisting of 3 episodes.
Coming in at sixth for the poll is Doukyuusei 2 with 77 Votes. Technically this is Hentai but it is mostly non-explicit softcore sex similar to shows like G-Taste, Nozoki Ana, and Rescue Me. The show is pretty basic in a nutshell protagonist meets a girl and by the end of the episode sleeps with said girl. And he eventually marries his “sister” with all of his one-night stands present at the reception. I did enjoy the sex scenes but I would have liked if in between there was more casual service rather than the cheesy drama and the horrible running gags. Doukyuusei 2 Special: Sotsugyousei on the other hand has no sex scenes instead focusing a lot on casual service like Pantyshots and Bath Scenes.
