The flavour rating in this book is off the charts; you've done an awesome job of evoking that legendary-Samurai-story feel. I'm interested in the application of the Bluebeard's Bride-style players-fighting-for-control-of-one-character system to Havoc, and I would lean in to it even more; give the aspects competing agendas to provide a reason to vie for that top initiative slot. The initiative system is cool but I'm not quite getting how players decide how many dice to roll for initiative or what costs there might be to trying for high initiative. I like that burdens don't kill the PC, just set back progress. It wasn't immediately apparent to me how many burdens a PC can take (I assume 3 of each since there are 3 spaces on the circle above?) and if there was any further effect for taking more than one of the same burden. (I would venture to suggest, since I've seen it used to good effect in several other entries, that some form of positive benefit for higher burden levels could work well here.) The way the retribution pool works builds well on the Havoc Pool system with more of a strategic, give-and-take aspect showing up. I'd also note that the Blade doesn't seem to have a Special ability; I'm not sure if that was a deliberate choice, but I always feel like each PC needs at least one. I love the concept here, I think it's well realized, and I definitely would be interested in trying it out once the campaign is filled out a bit more.
