The violence is a tad high, one character gets stabbed near the end. However, the real defining element that shoved this TV14 show into the WZ was sexual content. In one scene a girl gets undressed (down to her underwear) while under the impression she will be having sexual relations with another character. The scene then changes and she is in bed, seemingly naked and covered only by a sheet. What happened during the time jump is not confirmed, but very much implied (the fact that they are only about 16 years old and in a virtual game makes it all the more eerie). Near the end of the series, this same female’s shirt and over skirt are ripped off and the villain sexually harasses her. No details appear on screen, but the sounds made and the movement of the characters’ bodies make it very clear what’s occurring.
I personally didn’t like this show, mainly due to the numerous issues with the storyline and character relationships. If I were to attempt explaining these issues, I’d likely be writing long into the night. Besides, other bloggers have already done personal impression reviews of their own and some have said it better than I. Suffice to say, many people liked this show. A few didn’t like it. It seems to boil down to what kind of shows one likes. If you don’t mind plot holes so long as the romance aspect is always prioritized, you might like this (if the mature content doesn’t put you off your tea first). But if you like heroes that stand up for something besides their own selfish desires, and prefer romance to be a side affect, not a main dish, this show will likely be a sea of frustration for you.
