Reiko has a lot of grudges. The lord who enslaved her village. The warriors who enforced his will. The Kimura clan that accepted his pay. And, you know, everyone else on the planet.

It really speaks to who she is, that she's got all these grudges, and she's a professional killer, and she's neutral.

Ah, you loved me as a loser, but now you're worried that I just might win
You know the way to stop me, but you don't have the discipline
How many nights I prayed for this, to let my work begin
First we take Manhattan, then we take Berlin
- "First We Take Manhattan," Leonard Cohen.
