Samura ties closely with the Hogosha and AFA - both are organizations which hate foreigners with the heat of a thousand suns, and Samura gets it's racist/nationalist attitude from that.
Kishiro has always been more closely involved with the GMG and Blood Dragons, who are more embracing of foreign nations and non-kusari individuals, so long as such embrance furthers their goals (and the goals of Kusari as a whole).
I think that due to your past as a corsair, and taking hints from your allies in the hogosha and AFA, you're trying to make this new Kishiro faction too much like them - and in turn too much like Samura. It doesnt fit, IMO - and I dont think you should stick to that point of view with a Kishiro faction.
Samura is the corporation based purely on greed and power, Kishiro was always the faction that chose the path of honor and proper business (at least, as I see it, and as the rumors/infocards in-game hint towards).
EDIT:
Also this:
Quote:Samura has free access to our products. No restrictions there. Balance and profit for entire Kusari nation.
Kishiro hates samura, and samura hates kishiro in turn. Samura is a monster, it's the largest corporation in Kusari and has a firm grasp on all the major trade in Kusari - Kishiro has had to specialize in high-tech trade in order to keep their company alive, and suffered because of that. Kishiro is far smaller than Samura, and is always trying to wrestle control of various commodities and tasks away from the opposition.
If anything, Kishiro should be trying to sabotage Samura in the back alleys, careful not to be detected but doing whatever they can to disrupt the corporation. The blood dragons have been used in the past to handle this, since they hate Samura just as much.
