OBSURE O.V.A.S, *Amazing Nurse Nanako

While a bunch of OVAs at the turn of the century were focused the fads of nurses or maids as fanbait. Enter this 6-episode OVA, in which the title character Nanako is not only a nurse but also a maid. This was done as one of Pioneer(and later Geneon)'s line of OVAs like Tenchi-Muyo and El-Hazard, so there's a steady balance of sci-fi comedy and fanservice.

Nanako Shichigusa is a voluptuous ditz who works at a specialized clinic under the revered Dr. Omagi. Omagi himself is involved in several projects usually involving cloning and cybernetics. It's speculated that Nanako herself is at first the subject of a cyborg experiment but is in fact the clone of nurse that's been in Ogami's family for generations. Ogami is in co-hoots with both the U.S. military working on alien DNA, and the Vatican who want to use his cloning skills to make a copy of Jesus for them(if that's how the Second Coming was supposed to work!). Nanako is kept under a strict regime of keeping herself in shape as the subject of most of his experiments, although she is blissfully unaware of most of this. Several of her escapades have her dealing with mutant monsters, mad bears, enhanced psychopaths, not to mention the other crazies who work at her clinic.

This OVA was released through Geneon as three separate DVDs, as well as a 3-disc box set, but so far hasn't been picked up for a Blu-Ray release or a license rescue by another company since its original release. It's probably worth picking up if you're seriously into busty anime nurses/maids with wacky characters in it. Although the dub could use some serious work, aside from the main voice actress for Nanako is actually pretty passable despite working in only one other anime dub.
