One of the main characters is sometimes shown begging random girls to marry him, date him, etc. He is never violent or hostile, though he sometimes clings to or "chases" them. These scenes are always played for laughs, and are usually brief. S1E16: a man and a woman are shown to have an extremely physically abusive relationship, and she is terrified of him; it is unclear whether sexual violence also occurs. In a flashback, the man is shown seriously beating her as she cries and begs him to stop. Demon Slayer: Kimetsu no Yaiba Entertainment District Arc S1E1: a man tries to kidnap two young girls so they can work as undercover agents in the entertainment district. When asked why he is doing it, a young girl witnessing the scene replies in a panicked voice "Hentai! Hentai!". This does not end up happening as three 15 year old boys volunteer to take on the job. At the end, the man smacks the behind of one of the girls. S1E2: it is discussed how young girls are sold in the entertainment district. The young boys dress up as girls and get sold to entertainment houses. There are multiple young girls seen working in these houses. However, they work as maids and are not shown in the presence of men. The boys also work as maids. S1E3: a man compliments one of the boys on his looks and asks what the ‘young girl’ is up to. He gets hit. S1E11: on a flashback from a 100 years ago, it is explained how a 13 year old girl stabbed a customer in the eye. She gets reprimanded and the head of the house tells the customer that she will send him another pretty girl. The scenes suggest that the man was about to do something to her, but she retaliated by stabbing him. They also suggest that during that time, girls as young as 13 years old would have to entertain men. However, none of it is explicitly shown on screen. Season 3: it is revealed that the master of the demon slayer corps was 13 and his wife to be was 17. They had their first child when he was 15 and she was 19. It was an arranged marriage. Worthy of note: In S1E7+8, a 14 year old girl is sexualized a lot. This might be upsetting to viewers.
