None.

This show has almost the same amount of fan service as its predecessor does. Some female characters having big breasts and short skirts.

Two male characters get into a moderate fight while two others beg them to stop. A couple of punches and kicks at other points in the show.

Bad language isn't used often, a majority of episodes have no profanity whatsoever. However, depending on the translator for the subtitles (official translators, not Fansubs), along with the English dubbed version, language typically varies from mild to moderate. In the case of the English dub, it has slightly more language than the dub of the first season of Clannad.

Dub: "Shit" is used very infrequently; "piss" and "bastard" are fairly common, as well as "ass".

Sub: In most cases it should be a bit tamer than the dub. For example the subtitles provided by Hulu rarely have any bad language at all. With uses of even "damn" and "hell" being very rare in any episodes at all. The only instances of slightly stronger words was at least 3 instances of "asshole" in the whole series.

A character is arrested for dealing drugs (brief).

Nagisa's father smokes, and in one episode, Nagisa tries sake (some sort of Japanese drink) and gets tipsy.

A character begins to smoke, drink, and gamble after a tragedy. It's not shown onscreen too much.

(Deleted. Personal opinions about ratings are not appropriate for the Parents Guide.)

The emotional scenes are usually VERY heavy.

This show has a lot of scenes that can be hard to watch for some viewers, but there are also some moments that are meant to ease the tension.

A couple of possibly upsetting scenes.
