This anime looks pretty good for 1989 and has tons of gory moments that would make great gifs, that's really the only nice thing I can say about this anime. the story is complete nonsense, no ones motivation for anything is clear and nothings explained that well. it kinda just feels like nonsense soup with a bunch of fighting in-between. the summery of the plot here on MAL tells you way more then the show will. I had no idea the "demons" were actually aliens till I went back and read the description of it again
the battles can be pretty cool, creative and gory
and like I said it looks good for 1989.
5/10 it's really all style and no substance
