Wait - you should rebalance this.
Pool-neutral, you can either spend 40 points on your Influence and 10 points on your Charisma, or 30 on Influence and 20 on Charisma. Don't make him emotionless;
everyone has emotions, even cyberzombies. (It's just more remote for them.) If this is Gentleman Ronin, then he's not emotionless, he's simply very, very
controlled. Willpower 5 is fine, but bump the Charisma to 3, drop Influence by 1. Switch 'First Impression' for 'Code of Bushido' as Novocrane said.
Change Escrima to Kendo, Kenjutsu, or something more Japanese, and assemble for your GM four weapon-based bonuses for you to select from; try not to double up (i.e. +2 DV to Blades) if you can help it. Balance your Pistols and your Blades out, both at 5.
Remove SINner; get a good (level 4) false ID for your 'stuffer shack employee' self. Drop Vindictive, because ... it's just annoying, and I have a knee-jerk reaction to 'Vindictive' due to the original phrasing of it. Not even standard Samurai were 'you took the last piece of candy! Off with your head!'.
In exchange, pick up Vendetta - that is, if you're a
real Ronin, whose Lord (however you frame the term) was killed. (Call that 'kill the bastard what killed my Lord.') You also have to pick up Enemy, so that takes care of a big chunk of NegQual
there as well. After all, he's someone who wants you whacked because you're the last hanging thread - and you are, after all, out to kill him, right?? Make him someone serious, and then you'll be set.
