Occasional mild innuendo and fanservice involving teenage characters.

A running gag is made out of a female character with larger breasts having them referred to by others. How risque these references are depends on the translation; in the Viz subtitled version, Takagi refers to her 'chest', while in fan-subtitled versions, he refers to her 'big tits'.

There are some infrequent references to gravure magazines, boys going to see "sexy" movies, and boys getting "excited."

Some mild comic slapstick when a girl hits her boyfriend.

A boy is punched in the face in one scene, though there are consequences for the attacker. We briefly see a wound on his face afterwards.

There are some references to the possibility a man committed suicide, though this is later indicated to be false.

Occasional mild to moderate coarse language ('shit', 'bastard', 'damn', 'hell', 'ass', 'crap') in the subtitles. (May vary slightly depending on rather you're watching the official Viz stream or a fan translation.)

In one episode, Saiko says the word: "Bull" in a profane way. This really depends if you watch the Viz or fan-subbed version, though.

Some infrequent references to adults drinking and going on cigarette breaks. No actual smoking is seen, and no intoxication is depicted during the brief scenes in which adults go out drinking.
