i like shojo mangas. most of the mangas that i read are without blood and these kind of staff. my brother has something like 400 mangas and one of is battle royale. at first, i didnt like the drawing at all, but later on i started to read it for real and, what can i say? this thing is brilliant!!!
i love everything in it!
i love the blood the drawing, the story..
now:
art: amazing. its so detailed that i dont understand how the hell do they do it.
lets say, that if a bullet goes into someone's skall- you can see it comes in and blows the head out and takes out the eyeballs and everything(i know- gross but awasome!)

story: great. attractive and interesting, makes you wonder why is that show on and what will they do next. you just cant leave without knowing what will happen. and each student has its own story and personality.

characters: i think that i love shuya the most. i dont know why but i do.
later i startes to hate kiriyama so much but in the end. 'sob, sob' i allmost cried bebecause of him!!!!
i feel so sorry for him!

anyhow, to finish it, i think that if you love blood(because of that manga i started to love blood....) and really good and interesting characters, you HAVE to read battle royale. believe me- its so worth it.
