their are some episodes were you will need parental approval to watch it. the only ones i can think of are episodes 1 and i think episode 7 of season 1. i only just now started watching season 2 so i don't know all of them yet. but i can assure you that the rest is OK to watch, then again it has been a while that i have seen season 1. but yeah some people may want to watch a few episodes with their parents. i say a few cus my parents are the type of people who see one part of a anime and assume the worst about a show. so yeah watch a few episodes with your parents and see if you can get the go ahead.
