Sekai no Yami Zukan

A curated list of anime that is purely on delivering unsettling and eerie stories.

What belongs in this list:
- Chilling atmosphere
- Dark, psychological horror
- Creepy supernatural stories
- Minimal fanservice
- Unsettling, memorable plots
- Unique, eerie art

What doesn't fit:
- Fanservice distractions
- Horror-comedy blends
- Excessive gore
- Light or dramatic tones

I ran out of room. Everything on this list I rated 6 or 5/10, so these are looser recommendations.
