This deserves an English dub. I don't care if it's too gruesome but we have English gruesome cartoons like Family Guy, South Park, The Simpsons and Happy Tree Friends.
I was all set to finish this series and then the eps got taken down from RU-vid, it still makes me so sad. I remember reading the manga years ago but not sure if scans are still available. Wish they would release it through Drawn and Quarterly or Viz since they've translated and cleaned up both Rumiko Takahashi and Osamu Tezuka's work. Heck, even Saint Onii-san got a beautiful hardcover release! Edit: Apparently the manga site I used before got taken down due to licensing issues :(
