I'm 14 years old, and an avid manga fanatic. I borrowed this book from my friend a while ago. Reading the description, I didn't think it would be that great of a series, but after reading it, I fell in love with it. The storyline is funny, although sometimes dramatic. Yamada is an interesting character, and usually provides some laugh-out-loud moments. Such as, during an arguement with Nao-chan, he proposes to the back of her neck!! I would actually give this 4.5 stars, but since Amazon only has whole stars, I went with 4. Oh, and just a note, this book is not for those who don't like reading about blood, seeing as there are some rather...violent scenes involved.
