When I was younger and I didn't know what hentai or lolicon was, I thought this was super lit. Now I'm older and I was completely appalled.
It wasn't just the lolicon, (if you're into that, I guess) but it's the abuse, the manipulation and the pure disgust that I draw from like, all of the characters.
Shiren: Massive pedophile, but that's not his biggest problem. He constantly abuses Shinju, both sexually and mentally. He calls her a mannequinn, literally just because he's a jerk. Not to mention, not throughout the whole story, he never once tells her how he truly feels, which is pedophilia, but that's not the point. He's also crazy selfish and takes out his anger on Shinju when things happen to her that are directly his fault.
Every other character in the story (Expect Yuuji, I guess): They just either want to exploit Shinju or want to rape her. Mostly rape her.
Shinju: She's just a kid man. She needs to go to school, or call the cops. Probably both.
Bottom Line:
This is a perfect example of why Law and Order SVU is successful. Also, the police force in this timeline are horrible.
