Now... Age of this girls according to first chapter of manga: 13, 10, 16, 16, 13...
Don't anybody think, that with Japan problems with bulling, under-age prostitution, and children sexualization making something like this is rather "hardcore" ? I know, I know, fiction, free of speech, whatever, but tell Me what is the point in making a movie based on Guro manga by Uziga or fiction manga with under aged characters liking BDSM where manga is pointed towards minor audience? To prevent, to entertain, to encourage to do something like this? I thought, that Nana to Kaoru and Arashi version with live action movie, Sundome, was already on the border of good taste, but at least character portrayed there have Their adult age (16)... Here 10 years old girl likes BDSM, while She should be still playing in her sandpit with Her dolls.... But after read recently article about junior school gang, which prostituting fellows schoolgirls, of course in Japan, I still do not see a point to make something like this... I and know! I wrote something like this on the site full of loli! But where is the point, where fiction does mixing with reality, and in opposite direction, there always is some reality in fiction... I hope that this is made only to entertain, like porn, and not to encourage some sick peoples to try something like this with real minor persons.
