any good short anime series?

does anyone have good recommendations for short anime series, or anime movies? Don't really have time for series over 50 episodes with school and such. Appreciated!

Higurashi no Naku Koro ni; Plastic Memories; Girls & Panzer

Have you watched Kaiji yet? Very interesting art style and makes you feel the tension

If you're into isekai genre, lots of them have short seasons (12 episodes).
No game no life
Drifters
Darwin's Game
Bofuri (I hate being in pain, so i'll make a full defense build)

Enjoy!

I recommend Golden Boy, it is an old anime but super good, it will leave you wanting to see it again

Through this list, we hope your awareness of time and its imposed challenges will grow, and your next viewing will be gratifying.

Barakamon is a really good slice of life comedy! I don't watch too many short anime so can't really think of anything else at them moment tho

SamuraI Champloo is great, full of action
Demon Slayer also great animation with lots of cool fights

Depends what you are looking for in your anime

serial experiment lain, or elfin lied are short and sweet.

Shin Sekai Yori is really good story wise because it blurs the lines between good/bad and really makes you think. The new anime Promised Neverland is good if you like those 'oh god what the hell' anime but it's not finished if that's what you're looking for.
