During the second season, more nudity than in the first, but always with important parts obscured in one way or another, and most often played for laughs.

Extensive, exaggerated violence. Little by way of actual gore; the majority of explicit deaths are of Shikabane, which are already dead, and although it's graphic, it's not particularly gory.

Some profanity, but very infrequent and mostly mild.

None to speak of.

Many. The series hinges on a number of intense, emotional scenes to develop certain characters, and putting other characters into intense peril also. Some of those situations do result in the deaths of innocent people, or in serious injury to the central characters.
