Twilight Q(1987)

Twilight Q

A Knot in Time - Reflection Mayu found a camera floating in the ocean while she was on vacation. A very unusual camera. The film, mostly intact, reveals a picture of herself with a man she has never seen before. But that is not all. The unusual part is that this camera has not been made yet... and will not be made for another two years. And soon, Mayu finds herself swinging uncontrollably back and forth through time like a pendulum...

Mystery Case - File 538 A down-on-his-luck detective accepts the first case to come his way: surveillance of a man and a little girl. But who are they? And why do aeroplanes that fly over them turn into giant imperial carp? An investigator's normal methods do not apply when reality itself no longer applies...

Note: The series was meant to be a showcase for various anime directors. Unfortunately, only two parts ever got made.
