User blog comment:Robin Phantomhive45/Why is it rated R?/@comment-15657817-20160413170814

Compared to other R-rated stuff I would say it's pretty "tame". I watched it when I was in my mid-teens. As said, yes there's Mr. Sexy Harasho (who I actually ended up liking *flails into corner*), the occasional nudity and sexual reference, but compared to the novels even the anime is not that vulgar. As for blood, there is some, but it's not copious or excessive most of the time, and it's not ridiculously graphic to the point where it has to be censored. There's also the cussing but it's nothing worse than you'd hear in a school, I can promise you.

If you feel really uncomfortable with the content for some reason, wait to watch it until you're older, that's all I can say, I guess?
