I'm almost done reading the first Light Novel, and I've come to realize that it leaves out a few details. Rio's encounter with Izaya, and how Kyohei rescues Kaztano. Saburo Togusa is also mysteriously absent, even though he was throughout the entire first season of the anime. There are probably even more of these instances in the light novels I have yet to read.

Are the events that happened in the anime canon?
