I saw this movie many many years ago, I really don’t remember very much about it, it was a sci-fi anime movie, at least I think it was. The main character was a badass guy, I remember him wearing a trenchcoat and having some cool guns, I also remember the movie being quite violent and explicit. The most key thing I can remember is there was a completely naked girl strapped like a starfish to some big round thing, her wrists and ankles were strapped down. I think the guy was trying to save her or something. I also think I remember something about some kind of war with aliens, or aliens invading, or something along those lines.
