You mind gets blown at the use of a red filler tool, congratulations. Elfen Lied wasn't gorey, no matter what heppened everyone was just a balloon filled wil one color of red that sprayed everywhere and nothing else, no bones, no muscles, nothing, just red. Even when legs got ripped off there was only a couple fibers that didn't make an exact clean rip.
You want real gore? Shigurui's where it's at. When you see just two fingers break it accomplishes so much more than all the red in Elfen Lied could.
