If you go to
http://www.nemmelheim.de/kaiko/index2.html
you will find a website about the developers of Apidya - Kaiko.
They were a bunch of German guys who did Japanese style games.
In an interview with them:
T.R.Schmidt:
Is it true, that Apidya had a "II" in its name, because there was a Japanese game with the same name?
Chris Huelsbeck:
No, this was a gag to provide for some excitement....
