IMDB is not the best site you want to use, but even that site notes that it contains quite the violence and gore.

The violence isn't some cartoonish Looney Tune nonsense. You actually see characters get killed in gruesome ways (i.e. every time Saitama punches a monster, they rupture and explode in a mess of blood and organs flying around).
