So we completed the game. I can hand you the full character sheets if you want either here or in DMs.
Impressions of the game:
Overall I like the structure it encouraged me to lean into and I think it accomplished the story it was trying to tell. Solid One shot option at least for the group I have. I try to run things as close to the intention as possible it seems like it wasn't trying to define much more then structure of cursed blades grappling with strength of redemption over revenge. Maybe I am totally off base on that though.
a minor editing note: It says they start with 6 Penitence and if you accumulate 4 more you "lose your desire for vengeance and embrace the light of Amaterasu, ascending to Yomi, the celestial realm." is that supposed to happen immediately? And the character sheet only has the 4 marks so the initial 6s significance seems meaningless unless I am missing something or they should detail that. (Yes I am once again asking for more detail then the game needs)
Brief Summary of the specific of our game if its useful for you from the GMs perspective:
We started with some a lot of failed rolls and that lead to them starting on some virtuous impressions that influenced later decisions. It also meant they spent most of their time in Chapter 1. As a sidenote I do not think I prompted them to give me enough backstory on their hosts because they started with clear impressions and intentions of what to do before those went sideways.
They all ended up going into chapter 2 as some form of low class criminal who still taught them some odd virtue, so when they arrived at the estate and found the family sick they were primed to be more worried about helping with that then getting revenge on hurt induvial, even if the redemption started as: "Its not a victory to strike down the sick" they collective decided they were close enough that the process of tending would have pushed them over to leaving revenge alone at least for the most part.
