It’s an Anime about a haunted Japanese school dubbed in an MXC style parody and makes fun of everyone from Jews, Christianity, Japanese, Lesbians, Retards, even has a part that refers to Jesse Jackson as a racial grifter.
It’s a breath of fresh air and what comedy used to be.
2006 production with no association with Amazon, that's the only reason it's not ruined.
No need to watch it on prime either, it's free dozens of other places.
apparently, it did ok in japan but the Japanese studio didn't care about the western release and said they could do whatever with it
