soul healing anime

Sweetness and Lightning - Father Daughter wholesome.

Barakamon - similar

Mushishi - mystery solving with ancient spirituality twists

Aria - the anime that defined cozy shows. Absolutely nothing happens and it's perfect that way.

Flying Witch - Cozy everyday life as a witch

I don't know if any of these truly meet "consistent plot" though. Story driven stuff requires character arcs which usually don't conform well to "soul healing" shows because stories require drama and twists.

Ping pong the animation

Prozd put out some recent videos about anime recommendations, and it reminded me that Haikyuu is really fun and I would say it's good for the soul.

Yuru camp

My Love Story

The daily lives of high school boys

Tanaka-kun is always Listless

Senko-san, yuru camp, (mono is an anime that will be airing this season by the same creator of yuru camp)

Mashle: Muscles and Magic. It's a comedy that is also mostly wholesome. Like a parody of Harry Potter meets One Punch Man. What if OPM lived in a magical world where everyone else could use magic and then he went to Hogwarts?

Mushishi

I am the #1 Ranking of Kings pusher around here that shits food for the soul

Carole and Tuesday!

Spice and Wolf is what i like to watch when i'm having a mental health

Not exactly sure what you mean by soul healing but Food Wars (Shokugeki no Soma) is what I watch when I'm depressed. It's hilarious and the worst thing that ever happens is the main character loses a cooking contest. It also has legit useful cooking tips.

It is extremely horny though, not between the characters but every time someone eats something delicious they have a foodgasum.

If you're at all familiar with the fate universe, Today's Menu for the Emiya Family is the ultimate feel good, beautiful food vibes for me.

Azumanga Daioh counts, I suppose.
