Black Clover (2017-2021)

A grown women asks a 15-year-old boy if he'd like her to "reward him for his hard work", though he declines

There is a comedic scene where a female character looks down at her ripped clothes

There is one scene that takes place in a hot spring. Only the neck and above is shown mostly.

There is a character in the story who is obsessed with his little sister. This theme is repeated several times and he even gets upset when his sister likes someone else besides him.

A male character trips and lands face first in a woman's cleavage. The scene is brief, and neither of them seem to even acknowledge what happened.

Some characters wear tight revealing outfits.

One of the Black Bulls is often called a virgin street punk.

A grown man always has all of his clothes removed by coincidental circumstances. He's never really bothered by this and doesn't seem to notice or care a lot. On one occasion when he's already naked, he walks up to a girl without her seeing him at first, and she thinks she was going to get assaulted so she beats him up. It's played for laughs.

A female character falls and her breasts land on a male character's face. She's briefly embarrassed by this, and he shows no reaction. They move on quickly.

Some male characters are shown topless.

A group of magic knights in a hot spring try to climb up a wall to spy on a the ladies and their full backside is shown but frontal nudity is hidden and they obviously fail

In a non-canon ending clip, two of the younger female characters are pictured in a newspaper wearing lingerie from the midriff up. They are embarrassed by this and male characters are aroused.

A character is forced to do the laundry and gets embarrassed when he has to wash underwear. Played for comedic effect.

The series has no sexual references. It is pretty clean though some male characters are shown topless.

There is a lot of sexual comedy

The butt is shown a few times only for a few seconds.

The word sexy is used

A woman has sexual feelings for another man.

Female boobs were shown for about 5 seconds. Although it was not very clear because of green light.

It's mentioned here that a character is obsessed with his little sister. This is a mistake. He is obsessed with a Sister, a nun, who works at the convent he grew up at. The theme is indeed repeated quite a bit for jokes, and the character is oft reminded that he is too young, and being a woman of the cloth, she will never get married. To be clear, she has no familial relationship with him.

The main character is determined to marry a nun and repeatedly asks her to marry him and refers to her in a romantic way (nothing sexual) throughout the series.

There is an episode where the characters go to the beach. Noelle is shown naked in a changing room, though everything from the shoulders down is strategically covered. A young man has a nosebleed from seeing her. Later, Magna is shown wearing only a loincloth instead of a swimsuit. Luck playfully lights it on fire to make Magna run, and it eventually burns off, although no private parts are shown.

A female character's upper half is destroyed by an attack, and she regenerates unclothed with only fire covering her nipples, leaving a lot of exposed cleavage. For the rest of the arc, she is seen with either the fire or holding a censoring arm over them.
