Well I hope someone can tell with my limited memory as it was when I was little and it was around the same time as Guyver.
All I remember is that is was a dark (I think a lot of it was based in the night) anime and it had a moth or bat Woman in it who always faught with some beat guy. Again this was no light anime I think it was some of the more serious stuff.
I don't know if this is true but I think one of them got stronger as the moon came out or something.
Does anyone have a clue.
