Martlet is arguably the most racist in the group, but in a way that's more subtle.
Ceroba is racist towards humans because she thinks it's necessary: "It has to be done." Her heart's not really in it.
Martlet's racism is completely nonchalant in how it transcends the idea that she's "just following orders". She looks forward to her job. Humans are simply "others" to her. As shown when she has no immediate problem killing a human child, because it's just another day being a royal guard.
And Axis is simply programmed to be a human exterminator, because he's a robot.
