Nisemonogatari (2012-2012)

There are many sexual references and innuendos; very much more-so than the season's predecessor, Bakemonogatari.

It is implied that a girl sexually assaults a boy, only thing shown is the boy's shirt and pants being thrown off. This is played for comedy.

Koyomi is well known as "perverted" as the show proceeds.

The protagonist's younger sister is shown topless after getting her upper body blown off. It is later revealed that she has regenerative powers as she is a phoenix, which is why her breasts can even be seen in the first place.
