At least finish it before you make an assumption. A former yuri or shoujo artist wanna be, not getting anywhere so he ended up drawing Lolicon. Mangaka needs to eat, pays rent, spends money on research, etc. You do not need to be a pedophile to draw Lolicon. This is his third Yuri, did VERY well, and I think he now can leave his lolicon career behind.
Read Prism at the least before you make a judgement.
Seriously, defending someone who have drawn a full series of hentai with little girls getting raped, drugged and sold by men. Did he pay you ? With all the Yuri artists we have now, you could have chosen a better one to protect.
If it was only to get some money to eat and live, he could have made any kind of manga or work relating to draw, but HE HAS CHOSEN to draw hentai with little girls. He could have drawn grown adults women with big boobs and whatever fantasy shape you found on hentai, but no. And I'm pretty sure no one forced him to do it.
Also, a little reminder, even thought Japan don't give a fuck about pedophilia in hentai or manga/anime or the hyper-sexualization of children, what he did is a crime. Creating, consuming, storing and providing content of any kind (drawn or not) containing child pornography is a crime.
So supporting a guy who like to draw little girls having sex is not really my thing.
And yeah, I read Prism and, putting aside the plagia, no it's not okay to draw schoolgirls having sex like adults. Stretch is not a Yuri manga and there is not a single sex scene between the two main girls even though they are adults. And Vampeerz is not better. In addition to having the main girls being little girls who have explicit sex scenes, he adds another couple of little girls... What other sign do you ? A confession ?
