I'm majorly sadistic, but I have a bachelors in manipulation.
I would change my pic to Azumi to suit this, if not for;
1. She is a woman, and I a man.
2. She is subservient to Hideo Kuki.
3. She switches masters and becomes somewhat subservient to Yamato in A-1.
For reference, I would prefer Hideo as a master to Yamato, as Yamato is the manipulative type where as Hideo is more heads on. I could manipulate Hideo, but I would have trouble with Yamato.
