I read this manga as a freshman in highschool and recently found it and read it again (I'm in my 20s). Interesting read, certain points are much clearer to me now than they were then. PARENTS: I'd caution letting your children read this one. I let a friend borrow it in high school and found out later they had suicidal tendancies and I think the book negatively impacted them. It's meant to do the opposite, but I'm not so sure it accomplishes that.
