Some blood as the result of falling, being bitten by a dog, and the like.

Episode 17 features a room flooded with blood, and a series of later episodes include another room where the floor is covered in blood, as well as walls and a tub.

In the Funimation English dubbed version of the show, the word "bastard" is used.

Uses of "crap", "damn", "ass" and "god" are heard in various English translations and in some other versions.

Some characters smoke cigarettes, but it isn't talked about or glorified.

The show revolves around tracking spirits-- hence the title. Many ghosts are seen, often vengeful and frightening in a spooky way that may stay with you if you watch late at night. One episode features a dozen dead bodies come back to life. They are half-rotted, with skin peeling away from their heads and revealing their skulls.

Several cases involve the deaths of children, including one who froze to death.
