Horror series that has episodes with a runtime under 10 minutes.

The best horror anime (in my opinion) that I've completed thus far. AKA horror anime I rated 7/10 or higher. Some are not labelled as horror on MAL. Some are not really that spooky either. I also haven't seen every horror anime (yet).
Organized roughly by my rankings.

Part 2 (rated 6-5/10): https://myanimelist.net/stacks/64018

I also like Sankarea and Gakkou no Kaidan/Ghost Stories (dub) but I don't think of them as horror, so I didn't include them.

Also Memories is just referring to Magnetic Rose short film and Neo Tokyo is just referring to The Running Man and The Order to Stop Construction.


Horror shows I haven't finished yet + my current score (may change):
Kenpuu Denki Berserk (7-8/10)
Mononoke (6-7/10)
Jigoku Shoujo (6-7/10)
Shingeki no Kyojin (6-7/10)
Koutetsujou no Kabaneri (6-7/10)
Kiseijuu: Sei no Kakuritsu (6/10)
Red Garden (6/10)
Umineko no Naku Koro ni (6-5/10)
Tokyo Ghoul (5/10)

I hope you like the list and it inspires you.
Thank you for your interest!~ ｡ﾟ+.(･∀･)ﾟ+.ﾟ
