A popular comedic anime series. It began as a series of four movies, and later two alternate-universe OVAs (the "Vs." series) were released. This parody series references and lampoons a number of other works of anime from the 1970s and 1980s. Mari, for example, is an odd parody of Kenshiro from Fist of the North Star. The title itself is a reference to a Jackie Chan movie, "Project A." The A-ko series is as follows:

  • Project A-ko
  • Project A-ko 2: Plot of the Daitokuji Financial Group
  • Project A-ko 3: Cinderella Rhapsody
  • Project A-ko 4: Final
  • Project A-ko: Vs. Battle 1 - Grey Side
  • Project A-ko: Vs. Battle 2 - Blue Side
