Violence is no worse than most shonen anime (despite being seinen). There is blood but nothing too bad. More psychological than gory.

Violence is infrequent, but quite disturbing and severe when it happens.

The series doesn't focus on violence, and even when it happens (with some blood), it is never graphic or gory. However, it is never glorified and is presented in a realistic and quite harrowing way.

A girl is found unconscious and beaten in a shed and left to freeze to death, but is saved. No blood is present, but the scene is extremely disturbing and horrifying.

Infrequent violence with mild to moderate blood

Less violent than other psychological thrillers like Death Note, Monster, and Psycho Pass, but just as (if not more) heavy hitting

More focus on the emotional impact than on the violence

There is graphic child abuse present in many of the episodes.

It's stated that a young girl was kidnapped by a man, and then froze to death.

God damn, Christ's sake, oh my God, what the hell, hell, sucks, dick, crap, pain in the ass, geez, kick ass, asshole, bitch, holy shit, smart ass, dumb ass, sob, slut, screw, shit, goddamn, bastard, suck ass, pee like a mother, porn, kid porn, retard, jackshit, pain in the nuts, bullshit. All said throughout the series. As little as 1 word per episode but as many as 20 in some. Words are from the English dub.

No f-bombs

It should be noted that the manga has A LOT more language

A few of the characters smoke.

A man drugs children before kidnapping them.

A boy slams his fist into a desk and yells at one of his classmates. Not too intense but frightening since it happens with no warning.

Highly emotional and intense, with some disturbing scenes and images

This is an extremely intense, disturbing, and depressing series about violence towards children, with notable moments of cruelty and hatred. However, the ending is uplifting and heartwarming.

This show's story is about the protagonist preventing the kidnapping and murder of innocent children. There are moments that are darker because of dealing with themes of domestic abuse. Many scenes are intense and extremely emotional.
