Crows Explode (Blu-ray release 2014-10-22) is the third movie in the Crows Zero series (2007, 2009).  Again it features high school students fighting among each other to compete for the top position in the school.  As before there are also gangsters, and a son of gangster is involved.  So it offers more of the same.  However, in order to avoid repetition of the same plots in the first two movies, the protagonist here is given a personality that he wants to avoid fighting.  Since this is a fighting movie, his character implies that he cannot do much.  So the action goes to the subplots.  This creates the problem that this movie lacked focus.
