Sorry to resurrect this, but I've encountered a weird problem. On Ichirin's ending, the text for the fourth part (just after "For some reason my memories of the past few days are all fuzzy") does not appear. Then if you try to advance the text, the screen goes black.
I've not had any problems with Marisa and Kasen's endings, haven't been able to try anyone else's to see if they have issues like this.
