7. Corpse Party: Tortured Souls
To be fair, no other anime on this list does a better job at advertising through its title just how gruesome and gory it is, like Corpse Party: Tortured Souls. Another cursed school and a bunch of extremely unfortunate kids, the setting is nothing new, yet this anime more than makes up for it through excessive quantities of gore.
After performing a strange farewell ritual, a group of students from Kisaragi Academy find themselves trapped in Heavenly Host Elementary School (because ‘Hell’ or ‘Hellish’ would’ve been a little too obvious), a place in another dimension.
What follows isn’t much of a story, but more of a deeply disturbing collection of the most disgusting and brutal death scenes imaginable. Did I mention that we’re talking about kids here?
Only four episodes long, Corpse Party: Tortured Souls manages to pack in its short time enough nightmare fuel images to last for a lifetime. It may not have much of a story, but this anime will make you squirm in your seat, which is exactly the purpose of any good horror. If you still intend to watch it, just remember that you have been warned.
