Now I know what you are thinking, "b-but it's a fake anime the op came forward and said it was" when we don't know if that's even the real op or not ...anyways
Anyways I was looking through a site called darkanime.com while looking for connections I found a site called rdot163 and while looking through it I found a video called 皆殺しの祥 which translates to "The sign of mass murder" and the year of the video that it was uploaded is 2004 or 2007 and it shows the year it came out was 1980 along with the website kind of looking like bings old video search up thing years ago
I am NOT a troll before I get accused but I really don't know if this is a lead or not, also the video doesn't play, it just shows feathers at the beginning and then it just freezes
Also go for a punch is not the real name, if you don't believe me fine but I really don't know if this is a lead or not
