Depending on how little violence you want, here’s a few. I’ll put a star on ones that had absolutely no violence (to my recollection)

Steins;Gate (I don’t recall much gore, although some characters do die)

Vivy: Fluorite Eyes Song

Hyouka ⭐

Belle

A Silent Voice (no gore, but references to suicide)

ACCA: 13 Territory Inspection Dept. (one character gets shot at one point and ends up in the hospital. It’s not violent so much as dramatic)

Mushishi ⭐

Your Lie In April (no gore, but there is death)

Nichijou (horrific violence)

Sk8 the Infinity ⭐

Bocchi the Rock ⭐

Haibane Renmei (some violence in the first episode, but super worth watching)

Planetes (very little violence)

Noir (buncha people die, but there’s never any blood)

Niea_7

Serial Experiments Lain

Megalo Box (it’s a show about people punching each other, so as violent as you’d expect from that)

Nausicaä of the Valley of the Wind (very little violence)

Kyousougiga

Sonny Boy (very little violence)

Kiki’s Delivery Service ⭐
