Show has absolutely none in the entirety of it.

Show is fairly violent, lots of blood. The violence tends to get overhyped due to the concept and setting, however in actuality it isn't that bad. Very intense, but never gory.

Pretty intense, a decent bit of blood, but never anything overt.

Milder words (damn, ass, bastard) Show's content mostly relies on dark atmosphere than inappropriate content.

Milder usage, barely any at all.

Ass and hell are said a lot, but never anything more than that

None at all

Incredibly dark show, the whole center of the shows concept is death, and the themes surrounding it. Dark, gritty.

Most of the shows content comes from the dark atmosphere, lots of incredibly bleak and sad themes to the show. Some of the least friendly anime out there, at least in terms of themes.
