Who is Araragi supposed to look like in this scene? I'm watching one of the Monogatari episodes - Mayoi Jiangshi 2 (Second Season episode 8).



In this scene the style Araragi is drawn with changes radically, as does his hairstyle. 

The fact that the bloody eyes and seemingly explosive hair look so distinctive makes me feel like I'm missing a reference here.
This could possibly be a reference to the very obscure series The Soul Taker. The main character, Kyousuke Date, cried blood in few episodes. Here's a picture of him:



It's not an exact match, but Akiyuki Shinbo, the director of The Soul Taker, also worked on the Monogatari series, which made me think of this. (Source.)
