CK looks like she has a split-personality. She'll be sweet and docile on one spectrum and than show a sociopathic side if you push her buttons, or some sort of event triggers her to change. She would be like a double-edged sword.

Kin-Akari is a lone wanderer who prefers to be by herself and only accomplish what is needed like doing justice or finishing a task to get an award for herself. She'd also be more of the serious type.

Antagonist is strange candidate. Just find him mozying down the road or I guess in some winter tundra. You wouldn't be able to read him well and seeing how he carries a sword in the open, you wouldn't know what his intentions would be. He'd probably be a solitude type of guy.

I think, I'd choose Kin. We both have something over our faces, and she wouldn't judge me seeing how she has something over her eyes. I wouldn't be questioned why I have a creepy, beaked mask on.
