A young girl is held in confinement and tortured (off-screen, but heavily implied). She is seen in a straight jacket and constraints wearing a blindfold, and eventually begs to be killed. This is really disturbing and may unsettle some viewers.
Religion is one of the topics throughout the series.
Not overly disturbing or bloody, but very atmospheric and psychological, and usually moderately intense.
A bit more than the first half of the series contains some wholesome and light-hearted moments, but the show keeps getting darker and the characters become more serious as the plot progresses.
The whole concept of the show is how people can use a notebook to kill almost anyone they want to. It can be frightening and intense.
This is a darkest and intense anime series of Shonen Jump.
Prevalent themes of Shinigami and death. Frequent references to murder and suicide, and infrequent references to assault. Has many psychological aspects but isn't massively intense.
The series has a very dark tone, revolving around a young man who, being upset with crimes and criminals getting away, uses a notebook with the power to kill those criminals. His noble intentions, however, are quickly lost and he abuses his power. The series throughout is very intense and suspenseful. This all reaches its climax in the finale, when the protagonist becomes totally insane. There are some disturbing scenes throughout the series.
Intense and upsetting deaths include: a woman being hanged and another burned to death. The most upsetting and depressing factor is that both of these deaths were suicides caused by the main character after writing down how they die in the Death Note.
A man's family is slowly destroyed over the course of years due to his selfish actions. This can be emotionally upsetting for some.
A few of the characters in the series are Shinigami (Japanese soul reapers/"gods of death"), and their appearance may be frightening to some. However, they are not shown to do any scary actions, but just mostly spectate the happenings in the "Human World", much like the audience.
