Violence / Gore: A gang of robbers/terrorists take control of a shopping mall and take people hostage. They and others later in the show use guns and people do get shot, with some blood seen. A character is hit by a truck and there’s a spray of stylised black blood. A character with super-strength beats up people. A character commits suicide by stabbing themselves, and another by leaping off a building. Kido often kicks or punches Kano and sends him flying.

Nudity / Sexual Content: A character strips down to his underwear in one episode.

Theological Themes: The kids all have different eye powers. Humans can be possessed, although the possessor mostly doesn't actually exert their will over the possessee, i.e. take over/control them. Characters who die don’t necessarily stay dead. I’m being vague to avoid spoilers.

Negative Themes: Some mild swearing.
