Oh man, if you think that's bad, then don't read the manga. Towards the end, there's a serious Dragonball Z moment where it takes Shuya nearly five chapters between when he decides he needs to attack Kiriyama and when he actually starts the fight thanks to a lot of flashbacks and inner monologues. I like a lot of what the manga did in terms of fleshing out characters even more than the book had time for, but sometimes it veers too hard in the "this is manga, and we need to make sure our readers know it is manga!" direction for its own good. :)
