Warning: avoid cause of spoilers
One word: angry
Story: simple premise, girls kill themselves, one survives, survivor makes a new circle of girls, they commit suicide as well, the cycle continues. what makes me very angry is that they took a girl against her will to join and who was such a good friend; what right do they have to steal a life like that. I don't care about how she's like them, it's not right.
Art: works with the style of the story and I liked how they looked, even with the gore; its what I came for
Characters: Very much enjoyed Kyoko and her kindness until the end when she accepted her suicide attempt, then I got mad that she accepted so easily. I pitied Saya for a while cause I do understand her pain and downward spiral, but the same with Kyoko, I just don't accept her easy changed. She didn't deserve this fate but she also deserve this for being a horrible friend and person. Yes, death and suicide are always sad and are no laughing matter, but for how she is and what she did, she deserved the worst
Overall: I'd recommend if you're in for art and horror, but I do not recommend for someone that's sensitive of these topics or if you're like me and probably don't understand why the easy changes of these suicidal students
