Scenes with sexual undertones are very few and far between in this show. However, there is a brother and sister pair who seem to be in an incestuous relationship. The girl frequently makes sexual remarks about their relationship, flirts with her brother, and clings on to him. At the start of episode 3, she sticks her hand up his shirt and winds up crouching over him, giggling, as he seems to protest (all in front of other people in a restaurant). For a few seconds, there is a shot of the restaurant that appears to show her head positioned over his crotch area as he flails around. This is all played for laughs.

A doctor strips down to her underwear before treating a male patient (who is tied down to an operating table and unable to move for legitimate reasons). She makes some flirtatious remarks. No nudity is shown but she is seen in her bra and underwear.

An older man has a parental relationship with a young girl. There is a scene where he is helping her choose an outfit. During this scene, her naked torso is shown but her hair covers her breasts.

A woman is shown in her underwear and a man comments that she looks sexy.

Multiple people are shot onscreen, a man shoots his girlfriend on accident, a mafia murders multiple people, a slaughter is heard offscreen, a young boy's leg is ripped off, but regenerates, a young girl is shot on-screen multiple times, but survives, multiple adults are shot onscreen, and much else.

Minor acts of violence for comical effect. A man frequently asks girls to commit suicide with him and is in turn punched or slapped by another man. It's also implied the other man beats him up offscreen.

A boy collapses and is crying. A man then slaps him across the face. There are also flashbacks in which the boy is slapped by a man during his childhood.

A character throws a bunch of mobsters out of a window. The mobsters have funny faces while falling out so this scene is played for laughs.

The whole is pretty violent but not as much as something like Attack On Titan.

At one point a man shoots a guy continually, while laughing, he tells him it's more than he deserves, he does not know this man

Some uses of sh*t, son of a b*tch, ass, damn and hell.

The F word is used once at the end of ep. 7 in season 4 in the English dub

Some characters smoke, and characters that are of-age drink.

A man eats weird mushrooms that make him act funny and weird.

A character under the Japanese legal drinking age is shown drinking alcohol. This character is not a minor.

A few dead bodies are shown, but nothing that would be disturbing to a teen.

A man constantly attempts suicide but fails, this is done for comical effect, not gory or violent.

The main character grabs a bomb and puts it in a protected position. The bomb doesn't go off as it turns out it's fake. Frightening nonetheless but the characters position after he finds out will probably make you laugh.

Some characters make grotesque facial expressions. This could be slightly disturbing to younger viewers.

A boy's screams after having his leg cut off are very realistic. This may be intense for some viewers.

A young boy named Q who possesses mind control powers is seen with a doll that has blood streaming from it's eyes. The doll's head must be ripped off before it can use the boy's powers, when it does, the MC believes his friends are trying to kill him under mind control, but he then realizes that he was the one under control and is trying to kill them.
