Cream Lemon A-ko
It's one of the biggest non-secrets about this movie that it was originally intended to be an anime porno, but the creative team realized the film could have broader appeal if the hentai parts were scaled back some. It was intended to be the third volume of Cream Lemon, but only the scene with B-ko squeezing her boob in the bath was preserved from that stage of production.
There's a bit of mystery about what this original film would have turned out like. The Cream Lemon episode "Pop Chaser" in addition to featuring several sex scenes is quite funny in places, and has a lot of action. Positive reception to those elements in this chapter was probably a big factor in deciding to go mainstream for Project A-ko.
The story, as closely as I can tell from some vintage books I've procured, would have been about a rivalry between A-ko and B-ko's schools, possibly over possession of A-ko's classmate C-ko. A-ko has no superpowers but is a martial arts and weapons master, B-ko is a mad inventor and agressive lesbian, and C-ko is less childish and more submissive. The action apparently comes to a head after B-ko captures and has sex with C-ko, bringing on A-ko's retribution. B-ko has a henchman who resembles a teen Fist of the North Star, a male proto-Mari, and he presumably figures into the final fight of A-ko vs Armored Lingerie B-ko and her tentacle machines, as did Miss Ayumi in her own suit of powered armor. At the climax of the film the entire campus of A-ko and C-ko's school would have transformed into a giant Macross-like robot to battle B-ko's forces. Everyone's clothes are also torn off in this sequence.
It's interesting to think about, but I'm glad things turned out the way they did. Some of the books I refer to can be found at
