For the first 70 chapters or so, Wolfguy is a Gary Stu. He is glorified to no end. Every fight goes, "The enemy was strong, but Wolfguy was stronger." He was so perfect that he was completely unbelievable. The mangaka was definitely making a statement about who he thinks the perfect male should be.
Speaking about that, no 14 year-old should look like that. They're ninth graders? Really? I don't believe you. Not one bit.
However, the art was gorgeous. The female lead's eyes were made of wonder. The styles of each of the characters were unique, and I never had issues distinguishing between them.
The mangaka overused gore to prove his points (however well it was drawn). However, I rarely read seinen, and perhaps this is expected. However, it detracted from the experience for me.
My biggest issue is that there is WAY TOO MUCH rape. I mean, I get it, it's a useful plot device, but the author puts pages and pages of successive rape scenes. I don't get anything out of rape illustrations. I really don't. So it was annoying and pushed the gore way over any useful level.
The antagonists we really unrealistic. However, the antagonists were common for manga settings. Basically, the antagonists have a thirst for superiority. I can guarantee that neither me nor my friends will ever meet someone like any of the antagonists. As I do with most manga like these, I just sort of accepted it for what it was and continued reading.
Although I have a lot of issues with this manga, I still rated it a 7.5 . This is for a few reasons. The art is gorgeous. I quite enjoyed the relationship between the male and female lead. The female lead was not a useless barbie. Also the other students in the class were all well characterized.
P.S. The ending is not terrible. Although not explicitly stated, you do know how it ends. I wouldn't call it a cliffhanger.
