Complete breast and nipple is visible in bath scene.

Breasts are visible in a number of scenes, coming from the protagonist mostly. Not in a sexual context overall.

Several scenes of quick breast groping and other antics from an unpredictably villainous grandpa.

Some of the nudity could be seen as fanservice, though most of it is used in situations meant for light humor.

Excessive amounts of slapstick violence

Martial arts scenes where characters are battered, but not badly injured for the most part. Blood is usually minimal, although it's sometimes shown in small fountains for comical effect.

In a dream sequence, the main character is attacked by an animal. The screen gets covered in blood briefly.

Very occasional uses of 'shit', and some of 'damn' and 'hell'. One or two uses of 'b-tch' in the dub.

People sometimes gets drunk on sake. A few instances of smoking.

Nothing very intense, although most of the slapstick is unpleasant. There aren't many sympathetic characters aside from the male lead.
