In a later episode, Sebastian is seen to 'pleasure' a woman for information. Nothing drastic is shown, just a few sounds from the female in question.

A circus performer is seen to change corsets before her act. Nothing is shown, but it is implied as Ciel, who was hiding in the tent, is flustered.

There are children being held hostage in a mansion. As Ciel is there, they are forced to preform a circus act. One child falls off a tightrope to their death. Only the blood is shown. Another child is shown getting mauled by a tiger. Once again, nothing drastic is shown.

Sebastian is shown to kill many men.

There are a few character who smoke. There is also a minor character (Lau) who references a drug trade.

A circus performer tries to whip a tiger into submission. Sebastian stops it, but it could be upsetting to some viewers.

A flashback to Ciel's past shows him screaming for help and Sebastian arriving. Ciel also becomes triggered by a memory and throws up in the last episode.
