User blog:Robin Phantomhive45/Why is it rated R?

Ok well I haven't watched this show yet because I wanted to know why it's rated R. I'm 12 and I've seen stuff like Black Butler 2 and Ouran High School Host Club basically stuff with Yaoi, Yuri and blood. I just want to make sure it's not REALLY inappropriate before I watch it. ^-^

(Sorry if I posted this where it doesn't belong I don't really know how to use this :P)

~Thank You!
