Showa Monogatari (2011)

None. Just some romantic relationships between some characters.

Nothing very intense. Characters mainly yell at other characters. Sometimes characters nearly end up fighting each other.

One episode has a sister slapping her little brother for coming into the bathroom where she's standing. We don't see the slap itself, but the audience get the hint.

One episode has at least one brief scene of brother and sister fighting over a TV.

Nothing explicit.

Several scenes have characters drinking.

There are several dramatic scenes being spread throughout this 13-episode short series. But, they are not overly intense, and this anime series is suitable to be watched by a family.
