The story is completely safe for children and it doesn't swear once.. The jokes and plot are completely child-friendly and incorporates music with anime which is quite unique. The drawings were simple and effective and all scenes could be related to. I thought it was very clever with the jokes used and I found myself repeating some of them around the house. The characters were hilarious as even though they were in high school they acted so much younger or older. I enjoyed the first season greatly but as of yet I haven't watched the second season.
There is one or two lines which might be unsuitable for very young children but that could possibly be overlooked. There is nothing much else wrong with it except that if you want a short anime there are two seasons of it and a film although you could just watch the first lot of episodes.
Suggested age range:
Number of episodes:
There are 14 in the first season and 26 and an OVA. There is also a film.
Star ratings: (1*= poor or low content 5*= great or high content)
