At least in the Japanese version, the titular character Yumi can be seen naked (but only wearing a panty) in a few occations; two times due to her magic vanishing, and the rest due to herself bathing on a bathtub.

Mild scenes featuring bullying, arguements and fighting, some characters getting hurt, and characters in peril. Nothing very serious.

At least in the Japanese version, characters call other characters by mildly insulting words, like "baka" or "ahou", meaning words like "fool" or "idiot".

One episode has a man smoking a cigar. Characters can be seen drinking in a few episodes.

Nothing intense or frightening. This magical girl-anime series can be watched by any family.
