To me its Battle Royal, that manga is just unreal , sick, and dope. Its not a manga for kids you need to be 18 to buy cuz of Voilence and sexuality . The basist of the manga is about Kids who have to kill other kids from there class inculding Brothers,sisters, lovers and best freinds. If you havent read it READ IT NOW!!!!!!! and Yes it is that good. Also my secound best manga ive read is GTO , the story is great filled with Comedy ,Action and a mix of life issues . This manga is a must read aswell and to be honest i dont think i ever heard anyone who read it not like it .
