This was overall a fantastic anime, one that I watched when I was eleven and still love to this day. There are positive undertones; friendship, teamwork, and sticking together and supporting each other through tough times. There are generous amounts of both fighting, violence, and action, and the characters social lives at the academy they attend. There is some sex and nudity, although the lot of it is in the first three episodes, and then it virtually disappears. Although, there is a character that often surrounds himself with multiple women, but no sexual activity between him and said women is shown or implied. There is also another character who is shown nude twice, but nothing explicit is shown and all areas are covered or not seen. But beside that she is often scantily clad and has exaggerated features. There is no sex or implied sex, although she often tries to seduce Soul, who always rejects her advances. In actuality, there really is not much sexual things/nudity, and any mature eleven year old wouldn't be affected by it; personally, I was not affected in any way, and forgot about it entirely as I progressed in the series. And I have seen over ten anime series; you will not find one without at least a little bit of nudity or sexual references/content. Compared to other anime titles, it is almost nothing, if not something completely normal. There was a good helping of violence, but not enough to the extent where it could be called gore. There are some intense fighting scenes. There is mild cussing in the Japanese dub, but very light in the English dub, which is usually preferred anyways. There is one character who has phases of insanity, which is also an ongoing theme in the series. This character constantly undergoes physical and emotional distress. He can sometimes be frightening. Overall this is a great anime, good for BOTH GENDERS, I might add, since I am a girl. It has a great plotline with interesting characters, and is one of my favorites to this day. A recommended, but some parents should be wary with their kids. Just make sure they are aware about sex and smoking, and they are not too affected by blood, fighting, and violence.
