Touko-san uses self-destructing messages (possibly a callback to the self-destructing briefing cassette tapes from Impossible Mission). I have had fun using things such as wetransfer, gigafile, etc. to do something similar when sharing content online.

On track three of this section Fujimura recounts breaking a door by pulling a randoseru backpack through it. Those are designed to last for many years of a child's education. I like to use one as my camera backpack, and it has enough space in the main section for the camera body and two lenses. Other things (charging cables, UV filters, etc.) can be kept in the main pocket on the front.

Kokutou Azaka is one of my favorite characters from Kara no Kyoukai. I would like to know what happened to her after the story concluded.

In track two of this they discuss how "what they're saying might be [. . .]rather obvious, but it's full of difficult vocabulary [. . .] The opening has an unusual point of view - something obvious explained with a unique opinion. " Due to the novel's difficult vocabulary and complicated grammar, I think it can be good additional study material for high-level Japanese proficiency exams. It's certainly more interesting than boring textbooks because Kara no Kyoukai has ghosts, sorcerers, graphic descriptions of bloody murders, cannibalism, etc.
