the animation is breathtaking and smooth and the art direction is very stylized but yet simply beautiful.. which storyline is fun interesting supernatural thriller... it's definitely something you can lose yourself in they have a whole world doctors average Japanese school boy nicknamed leech stumbled upon. and becomes a champion...

The first few seasons I thought were good I after that the story repeats itself over and over. Eventually it lost it's charm because none of the main characters are in any danger of being killed. When you refuse to add any real drama it gets boring. Overall I'd say it was average and there are better anime out there that doesn't drag on.

It teaches on secret societies,witchcraft,duality, acting like these characters are trying to God over these other people! The logo has flames on it,which symbolizes where they'll be spending their life after they die. The title isn't referencing laundry detergent, it is referencing a reaper.
