I made my own Daemon Pair
They're based on a Nukekubi, a youkai that looks like a woman who's able to detatch her head and body
Honaka (Head), is the calm half of the pair, she's the planner and the voice of reason, keeping Kokoro calm and keeping them out of trouble when needed. Honaka has also some level of manipulation of her hair, enough so she can pick up certain small or lightweight objects and hold them if Kokoro is unavailable
Kokoro (Body), is the more reckless half of the pair, she's rather impulsive and playful, sometimes rushing into trouble without thinking. For a being without a head, she's very expressive, flapping her arms and hands around to display how she's feeling and she appears to be able to see and hear. Kokoro's completely incapable of verbal speech, but she is able to write and use sign-language to communicate if she desires, usually she has Honaka act as her voice, as the only one who can "hear" her
