Have to say the bit about pain made surprisingly sense.
I didnt read the novels or watched the animes and movies but i really think that Guillotine Cutter having a more active role in fighting makes a little more sense, at least in Oh Great style it would be strange that if he stayed in the back. Just a opinion.
It's been some time, like 10 years, since I last read Kizu, so I might just remember things wrong, but I did not remember Hanekawa having any interaction with those two, so that's new!
@volodyuka Yes, this interaction with Hanekawa is original in the manga. Both in novel and movie are entirely focus in monologue from Araragi (rather than monologue, it most likely entirely focus on Araragi's action). But in the manga, they not just focus on Araragi, but also other characters.
