Tanaka uses the word "erotic" on a few occasions, though rather he knows the true meaning of it is unknown.

A young-looking girl attempts to become taller to look 'sexy' in a yukata, and expresses dismay over failing to capture a look of an older girl due to her 'boobs' being much smaller.

In a montage of a girl trying to get the attention of a boy, the words 'sex appeal' are seen on-screen as she unbuttons a button on her top. (Nothing is seen except for more of her neck.)

Tanaka-kun's sister has a crush on him.

Infrequent very mild violence/slapstick. No blood or serious injury.

Occasional mild coarse language ('damn', 'hell', 'bastard', 'piss', 'crap', 'suck') in the English dub and official subtitles.

Some mildly frightening elements are briefly seen in a haunted house; however, the impact of this is significantly reduced by the fact that we also see the group put together the haunted house and know that none of it is real, with some of it turning out humorous in nature.
