Sankara is an odd horror anime. Unlike other shows in this list, the horror lies still until a human looks for its trouble.

Shigurui

Shigurui Death Frenzy (2007) Season 1 Episode 12 - YouTube

Shigurui is without a doubt the sickest anime on this list. All the characters are disgusting, yet, you will love them. Odd, eh?

Also, the anime is a whole lot uneasy. The scenes are boggling – to put it lightly. Be careful how it leaves an imprint on your outlook on life.

In particular, be careful of the nudity, sex, and rape scenes. This anime is big-time crazy!

Want a feel of impending apocalypse and strange disappearance? If yes, then Shinsekai Yori is what you seek.

This anime, like many dark kinds, shrouds its mystery behind a facade. Here, the world was peaceful, at least, until the protagonists found that it was all a lie.

Either way, the two versions follow D, the human-vampire hybrid, and his quest to free humans from vampires.

Vinland Saga

Vinland Saga Episode 08: Review - The Seekers of Atlantis

It is ancient Viking times, and no one cares about you. You either die or survive. For that reason, you have to strive and shed blood if the need arises.
