No seriously, all the ones you listed are light and cute in comparison. Way way more gruesome than M.D Geist or Fist of the North Star. Get through episode 1 and 2 then come back and lemme know how you feel. All the eps got uploaded on youtube too, if you never seen it id recommend it if you're in the mood for some uber violent anime.
Ar, me hardy.
