Kara no Kyoukai 7 really goes above and beyond in adding lots of original scenes that weren't in the novel. However, 1 piece of info you kinda miss out on is more background for Shiki's grandfather.
This guy is basically proto-Makihisa Tohno.
Unlike Shiki's dad and older brother, he did inherit the Ryougi's double personality trait, but he had no control or a good relationship with his murderous, insane 2nd personality. He killed lots of people, became a danger to his own family, and spent 20 years locked in an asylum.
