I can confirm this bug on multiple Kirikiri2 games, on the latest 2.14 version of WINE. It occurs with and without staging patches. (I'd include the requested log output, but it's pretty much identical to what has been provided, minus version numbers and directory names)
EDIT: Forgot to clarify: I'm using a full, purchased version of the game.
EDIT2: Wow, really bad at this. I've confirmed with Osananajimi wa Daitouryou (My girlfriend is the President)'s full version and trial version, which are the ones I'm referring to here. This issue affects other novels, but I'd rather not admit to my ownership of those...
