Story: Anime adaptation of the first game in the Rance series. Rance gets hired to find about a girl's whereabouts. He starts to work on his case while getting laid with as many girls as he can along the way. It gets a tinsy bitty dark(ish) towards the end, but there's not much focus on it and hey, it wouldn't be Rance without it.
Art: This is where this hentai really shines. They really did hit the nail on the head by going with studio Seven, it's like they were made for one another. Everything looks very good and stylish while the more comedic absurd scenes get 1000x times better with their animation.
Sound: The voices are all very good. Sound effects I felt that were a just a little bit lacking/low sometimes. Soundtrack sounded kind of bland in the sex scenes, with some of them even being just plain quiet. Great endings though, especially the last one.
Character: Loved all the characters. While I don't need to explain all my love for Rance and Sill again, all the girls really shine in this by being both very sexy and cute.
Enjoyment: Each episode felt fullfilling and fast-paced, developing the story while also having just the right amount of action. All the scenes looked great and the vanilla/cuteness amount in some of them were off the freaking charts (yes I'm looking at you two, Yulang and Menad). Last but not least, the lovely post-credits scene was the cherry on the cake.
Overall: One of the best hentai out there and probably the best adaptation I've ever seen, with lots of references and sometimes even going as far as taking things from the game too literally and making fun of it. Masterpiece.
