Angelic White Magical Girls is based off a hentai doujin of the same name. It takes some getting used to, but I personally enjoyed it once I did. The anime OVA was only about 5 minutes long, but enlisted some notable production company muscle and looks incredible.
Princess Lover! is based off an eroge of the same name and was the very first production by the Satelight breakoff group GoHands (Seitokai Yakuindomo, K, Coppelion, and most awesomely, Asa Made Jugyo Chu!).
This is a compilation of the six Utsukushiki Toushi Tachi OVAs, plus the two Rebellion / Artbook OVAs that followed. At the end I included all the images from the first two artbooks in a special montage. Sandwiched in the middle is all six of the special EDs, which are handily the most faptastic EDs you will ever see in any series.
Basically, these are all the cheesecake pics from the entirety of the Princess Lover! manga, which apparently only lasted 9 chapters. I love manga as a change of pace for fanservice.
A direct continuation of season one, Queen’s Blade – Gyokuza o Tsugu Mono pretty much takes over where season one left off with minimal changes. The only real difference being further increased production values.
Season two of the To Love-Ru anime, simply titled Motto To Love-Ru, picks up where season one left off and completed the remainder of the To Love-Ru Trouble manga, which would immediately spawn a manga sequel: To Love-Ru Darkness. Whereas season one spanned two cours (calendar seasons), season two is a mere 1 cour offering and as such, had half the opportunity for fanservice.
Based on a “choose your own adventure” styled gamebook of the same name, Queen’s Blade debuted to great fanfare in 2009- mainly because of the seiyuu cast, arguably the most star-studded cast of all time for any anime TV series.
This is the ecchi anime Kono Naka ni Hitori, Imouto ga Iru! (aka Nakaimo), edited down for added emphasis on fanservice and nudity, available via torrent as well as direct download.
