what kind of book report is it. i cannot think of any teacher that would let any student do a straight-up book report on a japanese comic book.
i've taken a few classes where graphic novels would be allowed (i had a class once that had a pretty major unit on graphic novels actually, we read the dark knight returns (frank miller wouldnt really be my preference as an example of graphic novel as literature but hey)).
but yeah doing a book report on a comic book is pretty lame, unless you were analyzing the medium as a whole or something which i doubt you'd be doing in a high-school level course that assigns "book reports"
either way your two days are long over, sport.
EDIT: no you edited in the two days thing. okay, maybe you should be a little clearer next time.
i DOUBT you will get anything out of this topic but good luck
