Here's another little tease about events that will be revealed in Bushido. I had wanted to create a parallel between Shiri's story and the swordsman's own traumatic past. Especially since he identifies with her so closely.
From the Hagakure:
"When I was young, I kept a 'Diary of Regret' and tried to record my mistakes day by day, but there was never a day when I didn't have twenty of thirty entries. As there was no end to it, I gave up. Even today, when I think about the day's affairs after going to bed, there is never a day when I do not make some blunder in speaking or in some activity. Living without mistakes is truly impossible. But this is something that people who live by cleverness have no inclination to think about."
