There is nonconsensual groping, touching, and harassment to one of the main female characters. The main character's grandfather makes a suggestive comment towards one of the female characters. This is played for disturbingly played for laughs, and never apologized for. Later on, a rape attempt is made and stopped and taken seriously. The manga tones down the sexist harassment tropes later on until they are no longer existent, but still has perverted comments made by one of the characters that are consistently chastised. In the early episodes, an attempt to frame a male character for spying on the girls' bath is made and failed. The episode's take on how harassment should be handled is treated rather poorly. None of the characters treat the harassment attempt as a good thing.
